AB  - The main aim of this research was to study the effect of two sowing times (early and late) on Fusarium and fumonisin contamination and some yield component traits of two maize hybrids from the FAO maturity groups 500 (ZP 560) and 600 (ZP 666) within a two-year growing season (2016–2017). F. verticillioides and F. subglutinans have been identified as Fusarium ear rot (FER) pathogens and potential producers of B-type fumonisins (FBs), with F. verticillioides as the predominant Fusarium species in both years. The incidence of F. verticillioides and FB levels were affected by sowing time and maize hybridity. With early sowing and the mid-maturity hybrid ZP 560, F. verticillioides and FB contamination were lower than with late sowing and the late-maturity hybrid ZP 666. Yield parameters also differed significantly between sowing time and maize hybrid treatments. Early sowing increased ear length (EL), number of grains per ear (NGE), grain weight per ear (GWE), and grain yield per hectare (GY). The late-maturity hybrid ZP 666 had higher yield component traits and GY than the mid-maturity hybrid ZP 560. EL, GWE, thousand-grain weight (TGW), and GY were affected by year. Interactions between sowing times and maize hybrids were highly significant (p ≤ 0.01) for FB level, GWE, and GY. The obtained results indicate the importance of applying early sowing to achieve high maize grain yields with lower contamination by F. verticillioides and FBs. Although mid-maturity hybrid ZP 560 and late-maturity hybrid ZP 666 showed significant differences in terms of levels of F. verticillioides and FB contamination, both were susceptible to F. verticillioides, with high FB levels. These results should be useful to breeders of maize hybrids to create genotypes more resistant to these fungal contaminants.

AB  - Fusarium head blight (FHB) is economically the most important wheat disease, 
causing yield and quality losses. Fungal species from the genus Fusarium are the 
main causative agents of FHB, with Fusarium graminearum as the predominant 
species. F. graminearum synthesizes more different secondary metabolites 
(mycotoxins). In wheat, the most studied mycotoxins are trichothecenes and 
zearalenone produced by F. graminearum. Trichothecene deoxynivalenol (DON) 
and its acetylated forms 3-acetyl-deoxynivalenol (3-ADON) and 15-acetyl deoxynivalenol (15-ADON) are the most detected in wheat grains. Strategies for 
controlling FHB and DON in wheat includе different preharvest and postharvest 
measures, emphasizing integrated approaches. The main aim of this review was 
to present some preharvest and postharvest strategies for integrated FHB 
management in wheat production.

AB  - The objective of this study was to evaluate the effect of applying lactic acid bacteria (LAB) and 
enzymes mixture inoculants (Sil-All and Silaprilis) on the chemical composition and 
fermentation of high-moisture grain silage of two maize hybrids Zenit and ZP 735. Maize 
hybrids were harvested at 68-72% of dry matter. Commercial inoculants were prepared and 
sprayed following the manufacturer's specifications. Silages were stored in glass jars with a 
special valve filled with water in the middle of the lid. Significant differences between hybrids 
were found for ash, crude protein, pH, and acetic acid. The hybrid Zenit had significantly higher 
ash (14.9 g kg-1
dry matter (DM)), pH (4.03), and acetic acid (6.3 g kg-1 DM), and significantly 
lower crude protein (89.0 g kg-1 DM) than hybrid ZP 735 (12.5 g kg-1 DM, 3.98, 5.1 g kg-1 DM 
and 101.2 g kg-1 DM, respectively). Compared to control, LAB+enzymes mixture inoculants 
stimulated ensiling of high-moisture maize grain. Inoculants decreased the contents of ammonia 
nitrogen and acetic acid, and pH value, and increased the contents of dry matter, ash, crude 
protein, crude fat, and lactic acid during silage fermentation than control. Accordingly, the 
application of LAB+enzymes mixture inoculants is justified and they can be recommended for 
high-quality silage production in feeding livestock.

ZP DSP 66, and one international durum line Cimmyt 7817) during two harvest seasons 
(2015–2016) has been studied. The four Fusarium species, F. graminearum, F. proliferatum, 
F. sporotrichioides, and F. verticillioides, were identified in 2015. A different structure of 
the Fusarium population, which in addition to F. graminearum, F. sporotrichioides and F. 
verticillioides, also comprised F. poae, F. semitectum, and F. subglutinans, was identified 
in 2016. F. graminearum was the predominant species in the durum wheat lines kernels and 
the potential producer of DON. The other Fusarium spp. were isolated sporadically and with 
a low incidence in the kernels. The incidence of F. graminearum and DON levels were 
significantly affected by the wheat genotypes and studied years and these parameters were 
negatively correlated. The incidence of F. graminearum was significantly higher in 2015 
(75.86%) than in 2016 (63.43%), while the level of DON was significantly higher in 2016 
(3.636 mg kg-1) compared to 2015 (1.126 mg kg-1). Statistically, there was a significantly 
higher incidence of F. graminearum in ZP DSP 66 (73.00%) and ZP 120 (72.75%) durum 
wheat lines than in the other durum genotypes. DON level was the highest in durum wheat 
line ZP 120 (3.854 mg kg-1). Considering all treatments tested, the mean DON level was 
2.381 mg kg-1, while the mean incidence of F. graminearum was 69.64%. Тested durum 
wheat lines showed susceptibility to F. graminearum, resulting in high DON levels in kernels. 
The results obtained suggest the importance of using the lines with improved resistance to 
Fusarium head blight in the breeding programs for new durum wheat cultivars.

Fusarium spp., while the Enzyme-Linked Immunosorbent Assay (ELISA) was used to 
quantify the total level of DON. Analysis of data was done by statistical method ANOVA 
(analysis of variance). Tukey’s test was used to compare means at a significance level of 5%. 
Correlation analyses were performed by Pearson’s test.
Based on morphological characteristics, four Fusarium species, F. graminearum, F. 
proliferatum, F. sporotrichioides, and F. verticillioides, were identified in 2015. A different 
structure of the Fusarium population, which in addition to F. graminearum, F. 
sporotrichioides and F. verticillioides, also consisted of F. poae, F. semitectum, and F. 
subglutinans, was identified in 2016. F. graminearum was the predominant species and the 
most common cause of Fusarium head blight (FHB) and the primary producer of DON. Other 
Fusarium spp. Were isolated sporadically and in a low incidence in the kernels. Fungal 
species from the genera Alternaria, Aspergillus, Chaetomium, Epicoccum, Nigrospora, and 
Penicillium have also been isolated.
The incidence of F. graminearum and level of DON were significantly affected by the wheat 
genotypes and investigated years. However, obtained results for these parameters were 
negatively correlated. Thus, in 2015, the incidence of F. graminearum was significantly 
higher (75.86%) than in 2016 (63.43%), while the level of DON was significantly higher in 
2016 (3.636 mg/kg) compared to 2015 (1.126 mg/kg). The highest and the lowest incidence 
of F. graminearum was on the kernels of line ZP DSP 66 (73%) and line ZP 34 (64.50%), 
respectively. The highest DON level was 3.854 mg/kg (line ZP 120), and the lowest was 
1.658 mg/kg (line ZP 41). The mean DON level was 2.381 mg/kg for all tested treatments 
and was above the maximum limit of 1.750 mg/kg prescribed by the European Regulation 
1881/2006/EC for unprocessed durum wheat, while the mean incidence of F. graminearum
was 69.64%.
Based on obtained results, tested durum wheat lines showed susceptibility to F. graminearum
and as a consequence higher accumulation of mycotoxin DON. These results indicate the 
importance of using less susceptible or tolerant lines to the pathogens of FHB and DON 
accumulation in the selection programs of new durum wheat varieties.

AB  - Pirot breed is a highly endangered autochthonous population of
sheep in Serbia, from which several important national brands originate: Pirot
lamb, Pirot carpet and Pirot hard cheese. In the available literature, there are no
data on hematological and biochemical parameters of the blood of this population.
The aim of this paper, which represents the beginning of the research, is to
determine the above indicators in the blood of Pirot Pramenka, which will
contribute to the preservation of this population. Since the breed affects the value
of blood parameters, the obtained results will be used to define reference intervals
for this population and compare with others. The study included 30 clinically
healthy sheep, 2-3 years old, from the area of Stara Planina. Blood samples were
taken by puncture to c. jugularis from which, after coagulation and centrifugation,
blood serum was extracted. Haematological analyzes were performed in the next
24 hours on a Siemens Advia 120 analyzer. The following parameters were
determined: total number of leukocytes, erythrocytes, platelets, hemoglobin
content, hematocrit value, MCV, MCH, PLT and MPV. Biochemical blood tests
were performed using Olympus AU 400 analyzers.The following parameters were
determined: total protein, albumin, globulin, urea, creatinine, glucose, total
bilirubin, cholesterol. Also, the following minerals were determined - calcium,
phosphate and magnesium, and following enzymes: AST, GGT and CK.
Descriptive statistical analysis was performed using the statistical package
STATISTICA (Version 8). Hematological indicators of Pirot pramenka are in
reference intervals for sheep, which indicates good animal health status.
Biochemical parameters of Pirot pramenka blood were within defined
physiological limits, except for creatinine and phosphorus levels, which were
below the lower limit, which is a consequence of dehydration and reduced
alimentary intake. In accordance with the obtained results, it is necessary to correct
the diet.

animal nutrition, and industrial processing. The standard agrotechnical measures
are used in its production. However, the utilization of bacterial inoculants is
becoming more popular due to their effect on increased soil quality, plant
performance, and yield while preserving and enhancing the agroecosystem. In
addition, bacterial inoculants can be applied together with pesticides used in seed
treatments. Our earlier results showed that the inoculation of maize seed with
plant-growth-promoting rhizobacteria (PGPR) increased the number of diazotrophs

AB  - The aim of this investigation was to estimate the influence of four nitrogen (N) rates (0, 60, 120 and 180 kg ha−1) and two ear inoculation treatments (inoculated with F. verticillioides and control) of two Serbian maize hybrids NS 6030 and ZP 666 (FAO 600 maturity groups) on some productive and quality parameters. The experiments were conducted in the two growing seasons (2013–2014). 

Nitrogen rates demonstrated a highly significant (P ≤ 0.01) influence on the number of kernels per ear (NKE), thousand kernel weight (TKW), the incidence of Fusarium spp. (F. proliferatum, F. subglutinans, and F. verticillioides) and level of total fumonisins B1, B2, and B3 (FBs). The ear treatment showed a highly significant (P ≤ 0.01) effect on maize quality parameters (NIK, the incidence of Fusarium spp. and FBs level) and significant (P ≤ 0.05) for TKW. 

Among identified Fusarium spp., F. verticillioides was predominant, with the highest presence found at 120 (62.41%) and 180 kg N ha−1 (61.81%). The occurrence of F. proliferatum was not significant at 0, 60, and 120 kg N ha−1, with the highest value recorded at 120 kg N ha− 1 (0.69%). The highest incidence of F. subglutinans was at 60 kg N ha−1 (4.94%). The higher presence of F. verticillioides was obtained in the inoculated (84.55%) compared to control ear treatments (36.59%), while it was vice versa for the incidence of F. proliferatum and F. subglutinans. The level of FBs was the highest at 120 kg N ha−1 (21.72 mg kg−1), especially in inoculated ear treatments (32.84 mg kg−1). A positive and significant relationship was found for NIK, with F. verticillioides and FBs level.

Investigated years significantly influenced the incidence of Fusarium spp. In addition, there was a significant effect of hybrids on NIK, the incidence of Fusarium spp., and FBs levels. A higher incidence of F. proliferatum and F. verticillioides and increased FBs level were recorded in NS 6030 hybrid compare to ZP 666. The mean FBs level in all the treatments was above a maximum limit (4 mg kg−1) adopted by EU regulation for unprocessed maize. The N rates did not have a consistent effect on the incidence of Fusarium spp. and FBs level. However, a hybrid effect was more consistent on the maize quality parameters, whereby the hybrid NS 6030 was more sensitive to fungal fumonisin producers and FBs contamination than ZP 666. In addition, the effect of the years significantly influenced the incidence of Fusarium spp., but did not affect on FBs level. 

These results indicate the importance of studying relationships between different factors affecting the occurrence of fungal contamination, therefore, improving preventative measures of maize protection would reduce the risks on animal and human health.

special focus on Fusarium spp. and deoxynivalenol (DON) presence, as a 
participant in Fusarium head blight (FHB) pathogenesis in two cultivars of Italian 
ryegrass K-13 and K-29. A total of 24 seed samples were collected during harvest 
in 2019.
By mycological analyses, Acremonium spp., Alternaria spp., Fusarium
spp. and non-sporulating species (Mycelia sterilia) were isolated on the seeds of 
both cultivars of Italian ryegrass. Among Fusarium spp., four species, F. 
graminearum, F. poae, F. proliferatum and F. subglutinans were identified in 
cultivar K-13 and three species, F. graminearum, F. poae and F. subglutinans, in 
cultivar K-29. F. graminearum and F. poae were identified as FHB pathogens, of 
which F. graminearum was dominant in both cultivars with 20.5% (cultivar K-13) 
and 32% (cultivar K-29) compared to F. poae which was present in both cultivars 
with a frequency of 0.5%. The frequency of DON positive samples was 100%. A 
statistically significant difference in DON level was found between the two tested 
cultivars, with a higher DON level in cultivar K-29 (5334.33 μg kg–1
) compared to 
cultivar K-13 (4738.58 μg kg–1
).
The obtained results indicate that two Fusarium species, F. graminearum
and F. poae, were FHB pathogens, with F. graminearum as the predominant 
species in both cultivars of Italian ryegrass. High DON levels (>3000 μg kg–1
) in 
the tested seed of Italian ryegrass indicate on potentially significant participation of 
DON in FHB pathogenesis, as well as a potential risk for the quality seed 
production, feed safety and the food chain in general. In Serbia, this is the first 
report about Fusarium infection and DON presence in ryegrass seed.

AB  - The aim of this study was to establish the total fungal (mould)
count in 79 commercial pig farm feed samples (42 samples for piglets, 29 samples 
for fattening pigs and 8 samples for sows) collected from the Serbian feed 
producers during the three-year period (2017–2019), as well as to evaluate the
percentage of contamination samples by fungi, especially species from Aspergillus,
Fusarium and Penicillium genera. Using standard mycological methods, the total 
count and identification of fungi were determined. Total fungal count was ranging 
from 1 × 102 to 1.41 × 105 cfu g–1 in the feed samples for piglets. Furthermore, in 
the feed samplesfor fattening pigs it ranged from 1 × 102 to 2.54 × 105 cfu g–1
, and 
from 1 × 102 to 1.93 × 105 cfu g–1 in the feed samples for sows. It has established 
the impermissible limit of total fungal count in 3.45% and 4.76% of a feed for 
fattening pigs and feed for piglets, respectively. Statistical analysis of the total 
number of fungi did not establish significant differences between the examined 
feed groups. Fusarium species were present in the most feed samples for fattening 
pigs (65.52%), followed by the feed for sows (62.50%) and piglets (47.62%). 
Aspergillus species were determined in 59.52, 58.62 and 37.50% feed samples for 
piglets, fattening pigs and sows, respectively. Penicillium species contaminated the 
lowest percentage of feed samples for fattening pigs (27.59%) and the highest 
percentage of feed samples for sows (37.50%). In a small number of samples 
Alternaria, Mucor, and Rhizopus species were identified. Based on these results, it 
can be concluded that the investigation of fungal contamination is an important 
indicator of a hygienic condition of feed intended for the nutrition of farm pigs. In 
addition, the percentage of fungal contamination of the examined samples indicates 
a potentially high risk to animal health. Due to that, a regular mycological 
evaluation is necessary to assess nutritional quality as one of the fundamental 
criteria for feed safety.

AB  - Maize silage is source of palatable and high-energy forage for ruminants. Therefore, production of high quality forage
maize represents an essential strategy for stable production of milk and meat on livestock farms. This study examined the
effect of harvest date (early dent, at half milk line, at three quarters milk line and black layer) on the quantitative and
qualitative parameters of whole maize plant under contrasting climatic conditions in the Srem - Serbia. A 2 × 4 factorial
(two years and the four cutting times) randomized blocks design was used, with three replications. The plant height, stem
diameter, number of leaves per plant, forage yield, dry matter yield and dry matter content were higher in 2014 probably
due to favorable weather conditions. With the delay of the harvest the forage yield, crude protein content, acid detergent
fiber (ADF) and neutral detergent fiber (NDF) decreased, and dry matter yield, dry matter content and ear percentage
increased. Sufficiently high dry matter content and ear percentage were achieved at the third harvest. However, the delay
of harvested time reduces the quality parameters of the biomass, but this loss in the entire plant is moderated by grain
filling.

AB  - In addition to nutritional value, a very important criterion for the selection of meat, for the modern consumer is the health aspect, i.e. the content of fat and the profile of fatty acids in meat. The content of fat and fatty acids, among other things, is conditioned by the feeding system and the rearing method. Lambs fed on pasture have a lower share of fat in the carcass than animals fed with a concentrated mixture, in a closed system. The recommended value for the ratio of polyunsaturated to saturated fatty acids is up to 0.45, and below 4.0 for the n-6 and n-3 fatty acids ratio. Taking into account that the influence of lamb nutrition on these relationships is significant, modelling of fatty acid composition should be directed to the lamb nutrition system which leads to a decrease in the content of saturated and an increase in the concentration of polyunsaturated (PUFA) fatty acids in meat. A feeding strategy involving a grazing feeding system of lambs results in a higher content of n-3 PUFA, CLA and a more favourable n-6/n-3 ratio of fatty acids, while the lamb meat originating from animals fed concentrated diets has a higher proportion of n-6 PUFA and a higher n-6 ratio/n-3 fatty acids, which exceeds the recommended value of 4.0. Conjugated linoleic acid (CLA) is of great importance since it has an anticancer, antidiabetic effect as well as an effect on the immune system, suggesting a direction for future research on lamb meat.

AB  - Given that Serbia (without Kosovo) has large areas under grassland, the aim of this study was
to analyze the variation and trend of the areas, total production and yields over 71 years
(1948-2018) and prognosis of yield in the next 30 years. The results indicated that the area of
grasslands in Serbia declined over the last decade. Most grasslands in hilly-mountain region
were degraded and without application of agrotechnical - remedial measures so that large
areas were lost. In Autonomous Province of Vojvodina, areas of grasslands have been
declining because have been converted into arable land. Total production of meadows
increased while total production of pastures decreased during the observed period. The
grasslands areas in Serbia showed low yields. In the Vojvodina region, meadows showed
decrease in forage productivity, while pastures showed increase in forage productivity. Areas
under meadows and pastures should be recultivated and brought into production in
accordance with the needs of livestock development. This will result in higher quantity and
higher quality production of green mass and hay. Unfortunately, depopulation and underrepresentation
of animals per unit area represented a limiting factor for grassland exploitation.
On the other hand, in the future yield growth rates of grasslands in Serbia and Central Serbia
and pastures in Vojvodina will very low increase. Contrary, yields growth rates of meadows
in Vojvodina will decrease by 2050.

AB  - The successful production of soybeans is largely dependent on the sowing time, because
every sowing outside the optimal time contributes significantly to yield losses. This field study
aimed to evaluate the e ects of sowing time (optimal—April 5; late—April 27) on the quantitative
and quality traits of three soybean genotypes (Galina—0 maturity group; Sava—I maturity group;
and Rubin—II maturity group) under dryland conditions in Vojvodina Province (Serbia) during
2017 and 2018. The genotype Sava had higher yield in climatic-unfavorable 2017, while Rubin had a
higher yield in climatic-favorable 2018. The yields significantly decreased when the soybeans were
sown in late April due to reductions in the number of pods per plant, seed weight per plant, and
1000-seed weight. The reduction in yield components was likely due to the accelerated senescence of
plants and the negative e ect of high temperature and low precipitation during the seed filling stage.
Accordingly, the various sowing times and properly chosen genotypes provide a better utilization of
soil and water resources. A proper genotype selection and sowing time can contribute to a high yield.
At the same time, the protein and oil contents can be altered by the sowing time, especially under
water stress during the reproductive stage.

AB  - The main nitrogen (N) sources in soybean production originate from soil fixing bacteria Bradyrhizobium spp. and from mineralization of soil organic N. These sources of N are often not sufficient to cover the N needs of the soybean. The present two-year field study aimed to evaluate the effects of soybean genotypes (Valjevka and Galina) and rates of starter fertilizer N (0, 30, 60, and 90 kg ha−1) on quantitative and qualitative parameters and on rain use efficiency (RUE) under contrasting weather conditions in the Pannonian region of Serbia. A field study conducted during two different growing seasons: first year with unfavorable weather conditions and second year with favorable weather conditions. As expected, the quantitative parameters, oil content, and RUE were higher in the year with favorable growing season, the second one. According to measured parameters, the genotype Valjevka performed higher yield potential as compared to the genotype Galina. The highest values of quantitative parameters and RUE were recorded at 60 kg N ha−1, protein content at 90 kg N ha−1 and oil content 0 kg N ha−1 (control). This study suggests that proper genotype selection and application of 60 kg N ha−1 as a starter dose with rhizobial inoculation could contribute to the high yield, while protein could be altered by N amount, independently on genotype.

AB  - Managing N, P and K inputs in semi-natural meadow production systems is important for achieving maximum yields in livestock farming. The objective of the present study was to estimate the effect of different NPK levels (N0P0K0, N50P50K50, N100P50K50, N100P100K100, N150P100K100 and N200P150K150 kg ha-1 yr-1) on the yield, quality and nitrogen nutrition index (NNI) in a grassland community of Agrostietum capillaris (semi-natural meadow) in western Serbia. The study was conducted during the seasons of 2005-2008. The values of the investigated parameters, except for the unit N uptake, were the highest in 2004/2005 due to favorable climate conditions. The levels of nitrogen significantly increased all of the studied parameters compared to the control treatment, except for unit N uptake. Mineral fertilizers at N200P150K150 provided the highest green forage yield (25.12 t ha-1), dry matter yield (8.12 t ha-1), crude protein yield (876.3 kg ha-1), nitrogen uptake (140.2 kg ha-1) and nitrogen nutrition index (70.2%), and the lowest unit N uptake (0.0022 kg N kg DMY-1). The use of mineral fertilizers increased green forage yield, dry matter yield and crude protein yield, increasing fertilizer from lowest to highest rate increased fresh and dry matter yield, as well as protein yield. Based on the results of the study, monitoring of nutrition indices would be necessary in order to increase productivity and economic benefits.

Studija je sprovedena tokom perioda 2005-2008. Vrednosti ispitivanih parametara, izuzev usvajanja azota po jedinici mase, bile su najviše u 2004/2005 zbog povoljnih klimatskih uslova. Nivoi azota su značajno povećali sve ispitivane parametre u poređenju sa kontrolnim tretmanom, osim usvajanja azota po jedinici mase. Đubrenje sa N200P150K150 obezbedilo je najveći prinos zelene krme (25.12 t ha-1), prinos suve materije (8.12 t ha-1), prinos sirovih proteina (876.3 kg ha-1), usvajanje azota (140,2 kg ha-1) i indeks ishrane azotom (70,2%), kao i najmanji unos azota (0,0022 kg N kg PSM-1). Upotreba mineralnih đubriva povećala je prinos zelene krme, prinos suve materije i prinos sirovih proteina, povećavanjem đubriva od najmanje do najveće količine je povećalo prinos sveže i suve mase, kao i prinos proteina. Na osnovu rezultata studije, praćenje indeksa ishrane azotom bi bilo neophodna mera u cilju porasta produktivnosti i ekonomske efikasnosti.

21 April - second date of sowing) and four nitrogen rates (0, 60, 120 and 180 kg ha-1) on the productivity of maize
hybrid ‘ZP 434’ in the Pannonian region of Serbia during 2016 and 2017 seasons. The dry period during late
vegetative development and grain filling stage in 2017 decreased ear traits, grain yield, starch and oil contents,
nitrogen agronomic (NAE) and nitrogen use efficiency (NUE). The highest number of grains per ear, starch and oil
contents, starch and oil yields and lower rainfall use efficiency (RUE) and protein content were obtained from the
early sowing date. The ear traits, grain yield, RUE, protein content, oil content and yield of starch, protein and oil
significantly increased while NAE, NUE and starch content significantly decreased with increasing nitrogen rate.
The results indicated a significant inverse correlation between starch and protein contents, which prevents the
improvement of these two parameters simultaneously. Thus, timely sowing and nitrogen input should be used as
long term management strategies for increasing maize yield and grain quality.

AB  - The objective of the present study was to investigate the susceptibility of maize hybrids to the natural occurrence of toxigenic fungal species, in particular toxigenic Aspergillus and Fusarium species, and mycotoxins (aflatoxin B1 (AFB1), deoxynivalenol (DON) and total fumonisins B1, B2 and B3 (FBs)). Grain samples of six commercial maize hybrids (MAS 34.B – FAO 300, MAS 40.F, MAS 48.L, KWS Konfites and ZP 427 – FAO 400, and MAS 56.A – FAO 500) were collected at harvest in 2018. A total of seven fungal genera, Acremonium, Alternaria, Epicoccum, Fusarium, Nigrospora, Penicillium and Rhizopus, were identified of which only species from the genus Fusarium were present on maize grains of all hybrids tested. The incidence of Fusarium spp. was higher in the hybrids MAS 48.L (54.6%), and MAS 56.A (53.3%), compared to MAS 40.F (37.3%), KWS Konfites (28%), MAS 34.B (22.6%) and ZP 427 (12%) hybrids. Among the identified Fusarium species (F. graminearum, F. proliferatum, F. subglutinans and F. verticillioides), F. proliferatum was present in all hybrids, ranging from 9.3% (ZP 427) to 30.7% (MAS 48.L ), whereas F. subglutinans was present in two hybrids, MAS 40.F (16%) and MAS 56.A (9.3%). The incidence of F. graminearum ranged from 0% (KWS Konfites) to 9.3% (MAS 34.B), while the incidence of F. verticillioides ranged from 0% (MAS 34.B and ZP 427) to 21.3% (MAS 48.L). In the samples, Aspergillus species were not identified. The effect of maize hybrids was significant on the level of mycotoxins. MAS 34.B hybrid had a statistically significantly higher levels of AFB1 and DON than other hybrids. The FBs level was the highest in the hybrid MAS 34.B (1202 μg kg-1) and the lowest in the hybrid KWS Konfites (88.33 μg kg-1). However, the FBs level did not differ between hybrids MAS 34.B, MAS 40.F, and MAS 56.L, MAS 40.F, MAS 48.L, and MAS 56.A, and KWS Konfites and ZP 427. In all hybrids, AFB1, DON, and FBs levels were below the maximum permissible levels stipulated by the legislation of the European Union and the Republic of Serbia in unprocessed maize.
The agro-ecological conditions in 2018 favored the development of Fusarium species on maize grains of the hybrids tested, especially fumonisin producing species.

AB  - Tanini predstavljaju heterogenu grupu polifenolnih jedinjenja koji se odlikuju sposobnošću taloženja proteina, polisaharida i minerala. To su fenolna sekundarna jedinjenja biljaka koja se većinom (preko 80%)  nalaze u drvenastim višegodišnjim dikotiledonim biljkama i manjim delom (oko 15%) u jednogodišnjim i zeljastim višegodišnjim dikotiledonim biljkama, ali su prisutni i u hranivima, ljudskoj hrani i nekim pićima (vinu na primer) i predstavljaju četvrtu najbrojniju grupu jedinjenja u vezikularnom tkivu, posle celuloze, hemiceluloze i lignina.  Tanini se sastoje od 12 do 16 fenolnih grupa i 5-7 aromatičnih prstenova. Nalaze se u gotovo svim delovima biljke: u semenu, plodu, listu, stablu, kori i korenu, i njihova primarna funkcija je zaštita biljke protiv patogena, insekata, štetočina i biljojeda. Iako postoji nekoliko klasifikacija, glavna podela tanina je na kondenzovane i tanine podložne hidrolizi. Tanini se odlikuju astrigentnošću, oporim ukusom i dugo su smatrani isključivo antinutritivnim materijama koje dovode do brojnih smetnji i zdravstvenih problema životinja. Od 80ih godina XX veka počinje da se ispituje njihov pozitivan uticaj na životinje. Biljke mogu da sadrže i do 20% tanina u suvoj materiji. Sadržaj tanina zavisi od biljne vrste, fenofaze, a menja se i u skladu sa uslovima okoline. Najčešće ispitivane krmne kulture koje sadrže tanine su: žuti zvezdan (Lotus corniculatus) sa sadržajem tanina 20-40 g/kg suve materije, zatim esparzeta (Onobrichis vicifolia) sa 5-22 mg/g zelenog lista, hmelj (Humulus sp.), cikorija (Chicorium intybus), ajčica (Coronilla varia), čič (Astragalus cicer), sula (Hedysarum coronarium),  karob (Ceratonia siliqua) i druge. Zadnjih godina sve više se u ishrani preživara koriste ekstrakti tanina dobijeni od drvenastih vrsta, pre svega hrasta (Quercus sp) i kestena (Castanea sp) koji u zavisnosti od proizvođača sadrže oko 70% tanina. Proteini su najskuplja komponenta hrane za životinje i teži se njihovom boljem iskorišćavanju. U ishrani preživara, usled buražne fermentacije dolazi do određenih gubitaka proteina. Iz tog razloga se teži povećanju sadržaja proteina u hrani za preživare koji izbegavaju buražnu fermentaciju (tzv. „by-pass“ proteini). Tanini sa proteinima u uslovima neutralne sredine (kakva je u buragu) stvaraju nerastvorljive komplekse, dok u kiseloj sredini (kakva je u tankim crevima) dolazi do razgradnje ovih kompleksa. Zahvaljujući ovim osobinama tanina, može se uticati na povećanje sadržaja „by-pass“ proteina u ishrani preživara i time optimalnije normirati obroci. Reaktivnost tanina zavisi od njihovog izvora, oblika, koncentracije,  pH vrednosti sredine, vrste proteina sa kojima reaguju i drugih faktora. Usled korišćenja tanina može doći do optimalnijeg iskorišćavanja proteina što dalje može da vodi ka poboljšanoj produktivnosti životinja (veći prirasti, povoljnija konverzija hrane, veći prinosi) kao i do promena masnokiselinskog sastava mesa i mleka usled izmenjene buražne fermentacije. Takođe, primećeno je da tanini povećavaju otpornost preživara na crevne parazite, poboljšavaju antioksidativna svojstva i doprinose boljem zdravstvenom stanju životinja. S druge strane, ukoliko su koncentracije tanina u hrani za životinje previsoke, mogu se ispoljiti negativni efekti, od kojih su neki: niska konzumacija hrane usled neprijatnog (oporog) ukusa, smanjena svarljivost vlakana i šećera, niži prirasti, različiti oblici intoksikacija životinja i drugo. Takođe, tanini pored proteina mogu reagovati i sa enzimima, kao i sa neproteinskim organskim azotnim jedinjenjima. Upotreba tanina u ishrani preživara je veoma aktuelna. Ipak, potrebno je obaviti još istraživanja kako bi se odredile optimalne koncentracije različitih vrsta tanina iz različitih izvora i u potpunosti razumela njihova uloga, svarljivost i reaktivnost u organizmu životinja.
AB  - Tannins represent a heterogeneous group of polyphenolic compounds that are characterized by the ability to precipitate proteins, polysaccharides and minerals. These are phenolic secondary compounds of plants that are mostly (over 80%) found in woody perennial dichotyledonous plants and a smaller part (around 15%) in annual and perennial dicotyledon plants, but also present in nutrients, human food and some drinks (wine on example) and represent the fourth largest group of compounds in the vesicular tissue, after cellulose, hemicellulose and lignin. Tannins consist of 12 to 16 phenolic groups and 5-7 aromatic rings. They are found in almost all parts of the plant: in the seeds, fruits, leaves, trees, roots and roots, and their primary function is to protect the plant against pathogens, insects, pests and herbivores. Although there are several classifications, the main division of tannin is on condensed and hydrolisable tannins. Tannins are characterized by astringency, resistance to taste and have long been considered only antinutritive substances that lead to numerous disorders and animal health problems. From the 80s of the 20th century, their positive impact on animals is examined. Plants can contain up to 20% tannin in dry matter. The content of tannin depends on the plant species, phenophase, and changes in accordance with environmental conditions. The most commonly studied fodder cultures containing tannins are: Birdsfoot trefoil (Lotus corniculatus) with tannin content of 20-40 g / kg of dry matter, then Sainfoin (Onobrichis vicifolia) with 5-22 mg / g green leaf, hops (Humulus sp.), chicory (Chicorium intybus),  Coronilla varia,  Astragalus cicer, sulla (Hedysarum coronarium), Ceratonia siliqua and others. In recent years, tannin extracts of woody species, primarily oak (Quercus sp) and chestnuts (Castanea sp), are used in ruminant nutrition, which, depending on the producer, contain about 70% tannin. Proteins are the most expensive component of animal feed and are striving for better use. In the feed of ruminants, due to sterile fermentation, certain protein losses occur. For this reason, it seeks to increase the content of proteins in food for the ruminants that avoids fermentation (the so-called "by-pass" protein). Tannins with proteins in the conditions of a neutral environment (such as in the rumen) create insoluble complexes, while in the acidic environment (such as in the small intestine) there is a degradation of these complexes. Thanks to these tannin properties, it may be possible to increase the content of by-pass proteins in ruminant nutrition and thus to better normalize the meals. Reactivity of tannin depends on their source, shape, concentration, pH of the environment, the types of proteins with which they react and other factors. Due to the use of tannins, optimum protein utilization can be achieved, which can lead to improved animal productivity (higher growth, better food conversion, higher yields), and changes in the fatty acid composition of meat and milk due to modified fermentation. It has also been observed that tannins increase the resistance of ruminants to intestinal parasites, improve antioxidant properties and contribute to a better health condition of animals. On the other hand, if tannin concentrations in animal feed are too high, negative effects can be observed, some of which are: low consumption of food due to unpleasant taste, reduced digestibility of fibers and sugar, lower growth, different forms of animal intoxication and other . Also, tannins besides protein can also react with enzymes, as well as with non-protein organic nitrogen compounds. The use of tannin in ruminant nutrition is very actual. However, more research is needed to determine the optimum concentrations of various tannins from different sources and fully understand their role, digestibility and reactivity in the animal's organism.

AB  - The area of central Serbia is very suitable for sheep production, because of it’s hilly and mountainous configuration. Such area is rich in pastures for ruminants. In the territory of central Serbia, representative of autochthonous (indigenous) sheep breeds is pramenka (zackel) with its differentiated strains: Sjenica strain, Svrljig strain, Krivovir strain, Karakachan strain, Pirot strain, Lipa strain and Bardoka (White Metohian strain). Aim of this study was to investigate Krivovir strain: number of controlled heads and their part in total sheep population, their productivity parameters and milk parameters. In this study, total of 789 adult animals were observed. Average observed body weight (BW) of lambs were: BW on birth 3.22 kg, BW after 30 days 10.55 kg and BW on weaning 24.99 kg, while BW of adult sheep was 50.52 kg. Fertility index was 1.17 and average wool production was 2.88 kg. Average lactation after weaning lasted for 100 days, with milk production 65.16 kg, 3.91% protein and 6.72% milk fat. Krivovir strain is participating with 0.4% of total number of controlled sheep in central Serbia. Although in small number, this strain is irreplaceable in sustainable systems because they are evolutionary adapted to the conditions in which they are reared and because of their contribution to gene pool and agro-biodiversity.

AB  - The high price of protein nutrients as well as import orientation
have triggered the demand for alternative protein sources in the feeding of lambs.
In addition, it is necessary to take into account the degree of degradability of
proteins. In order to ensure optimal amino acid pool for high genetic capacity of
lamb growth, it is important to provide a protein fraction that avoids degradation in
the rumen. An excellent source of protein that slowly degrades in the rumen is fish
meal. However, given the recommendation of its non-use, the effects of the use of
Eko fish meal, as a fishmeal substitute in diet of lambs of average body weight of
about 14 kg and age of 30 days, were examined. The source of protein did not
significantly affect the growth rate and the efficiency of food utilization in the
lambs of MIS population in fattening (P>0.05), suggesting that fish meal can be
successfully replaced by Eco Fish Meal. As an alternative to soybeans, in diet for
lambs in fattening, the following were used: sunflower meal with the addition of
fibrolithic enzyme, lupine, fodder peas, fodder beans were used, while in the more
exotic areas the following were used: castor cake, pomegranate peel, product
obtained after rice fermentation without any harmful effect on the biological
efficiency of growth and food conversion.

AB  - The area of central Serbia is very suitable area for small ruminant production, due to it’s hilly-mountainous region, rich in pastures, and free from heavy use of pesticides, which make it great for organic production. In the territory of central Serbia, representative of autochthonous (indigenous) sheep breeds is pramenka (zackel) with its differentiated strains: Sjenica strain, Svrljig strain, Krivovir strain, Karakachan strain, Pirot strain, Lipa strain and Bardoka (White Metohian strain). Aim of this study was to investigate Lipa strain: number of controlled heads, their productivity parameters and milk parameters. Observed data were processed using the statistical package Statistica for Windows (Stat. Soft Inc.), whereby the basic parameters of descriptive statistics (arithmetic mean, variation coefficient, standard deviation and standard error) were calculated. In this study, total of 840 adult animals were observed. Average observed body weight (BW) of lambs were: BW on birth 3.56 kg, BW after 30 days 12.72 kg and BW on weaning 27.14 kg, while BW of adult sheep was 66.18 kg. Fertility index was 1.31 and average wool production was 3.24 kg. Average lactation lasted for 125 days, with milk production of 102.16 kg, 5.74% protein and 7.12% milk fat. Indigenous breeds are irreplaceable in sustainable systems because they are evolutionary adapted to the conditions in which they are reared. Lipa strain is one of them and due to it’s productions in humble conditions it is one of the key for sustainable sheep production.

AB  - Forage grass-legume mixture are highly productive ambience of
different plant species intended for animal nutrition. The competitiveness of
species in the mixtures is one of the important traits that significantly affect
grassland management. The goal of the study was to evaluate nitrogen nutrition
index of pure lucerne and their mixtures with grasses and sainfoin subjected to four
different levels of nitrogen in three years duration. The experiment had a
randomised block design with four replicates and eight treatments. Examined
treatments were pure lucerne crop and mixtures of lucerne, orchard grass, tall
fescue and sainfoin in the same proportion and four nitrogen fertilization rates (0,
70, 140, 210 kg ha-1). Pure lucerne achieved higher yield by 12.8% than their
mixtures. Forage production was the highest at 210 kgN ha-1 which was 14.6%
more than treatments without nitrogen. Nitrogen uptake by the plant that were
fertilized with N was significantly higher than the plants that were not fertilized. In
all three experimental years control nitrogen treatment had satisfactory value of
nitrogen nutrition index while other N treatments showed luxury consumption. Soil
N reserves and nitrogen fixation in the treatment where N was not applied, were
sufficient to ensure enough biomass production.
