AB  - This study provides an overview of food prices in the Republic of Serbia from 2016 to 2023 amidst the challenges faced by the meat processing industry. Household spending trends reveal a notable shift, marking an increase since 2016. The study explores meat products' affordability and nutrient density, challenging conventional assumptions. Mortadella emerges as the most nutrient-dense despite its lower calorie content due to high protein content, while pâté commands a higher market price despite its lower nutrient quality.

AB  - Milk fat content stands out as a crucial production trait in cows, and this study delves into its variability based on various factors. The
research investigated how the housing method (large farm or individual producers), origin (domestic-rearing or imported cows), and
calving season collectively impact this trait. Cows reared on the farm exhibited a higher milk fat content compared to those raised by
individual producers. Additionally, primiparous cows from domestic rearing displayed lower milk fat content than their counterparts
of imported origin. Among primiparous cows on the farm, those calving in the summer and autumn produced the highest milk fat
content. Conversely, primiparous cows calving in the spring season and raised by individual producers recorded the lowest milk fat
content. The statistical analysis revealed a highly significant influence of calving season, with a noteworthy interaction among housing
method and origin on the observed trait. The significance ranged from statistically highly significant (P ≤ 0.01) to statistically very
highly significant (P ≤ 0.001).

AB  - The greenhouse effect has led to a changed precipitation regime, an
increase in the average temperature, the occurrence of extreme meteorological
events (droughts and floods) and the like. All this harms the yield and quality of
feed, the incidence of mycotoxins in food, reduced productivity of animals, the
incidence of new and non-specific pathogens, the development of diseases, etc.
According to the FAO and the World Bank, the countries most affected by climate
change are the countries of Central Europe and the Mediterranean. The population
of people living in rural areas and engaged in agriculture will be particularly at
risk. With difficult working and living conditions and reduced incomes, there will
be an increased migration of the population to the cities. The simultaneous decline
in agricultural production and increased food demand will lead to a food supply
crisis (FAO predicts that by 2050 the global population will increase to 9.6 billion
people, resulting in a demand for 70% more food than in 2013).Cattle production is
affected by the climate in different ways, directly and indirectly. Livestock
condition, production level, reproductive performance, morbidity and mortality are
correlated with climatic conditions. The most pronounced negative impact on the
health and welfare of animals is a phenomenon called heat stress. Exposure to
microclimatic conditions characterized by a combination of high temperature and
air humidity overcomes the ability of animals to maintain normal thermoregulation
and constant body temperature, leading to an increase in body temperature that
exceeds physiological limits. In addition to the direct effects of heat stress on the
productivity, reproduction and health status of animals, global warming also affects
animals indirectly through reduced soil fertility, water availability, crop yields,
quality of plant nutrients and the circulation of pathogenic agents. Finding a
solution to mitigate and prevent the consequences of unfavourable climatic and
microclimatic conditions is a challenge for the entire scientific and professional
community, but also for every cattle breeder. Solutions can be biological and
technological. Biological ones refer to the animals themselves (breed selection,
selection for functional traits, selection for adaptability to heat stress, use of
genomic selection, artificial insemination programs, herd size). Technological
solutions relate to how animals are kept (free system, in outlets with canopies, use
of grazing), facilities (new materials and technical solutions in the construction of
facilities, use of insulating materials, regulation of microclimate conditions in
facilities - ventilation and air humidity), nutrition and feeding (feeding method,
feeding time, use of new types of feed, continuous water supply, etc.).The goal of
agricultural production is to ensure food security in the face of climate change, and
it is one of the most demanding tasks facing humanity

AB  - The term heat stress in mammals implies the sum of environmental influences that cause an increase in the body temperature of the organism. In dairy cow breeds, heat stress primarily reduces milk yield and milk quality, and then impairs fertility, welfare and causes changes in behaviour. This has especially come into the focus in recent years with the increasingly pronounced consequences of climate change. The aim of the research was to determine the effects of various fixed factors on milk yield performance traits of cows: MY – daily milk yield (kg/day), MF - milk fat content (%) and MP - milk protein content (%). The total data set contained test-day information for the analyzed traits during the summer period, and the effects of breed, breeding location, order and stage of lactation, year and season of calving, as well as the month of control were investigated. From the total set, selected data were used that correspond to the values of the daily temperature-humidity index of at least 72 (THI≥72), as an indicator of the occurrence of heat stress. Manifestation and variability of the studied traits, as well as the influence of individual factors on the studied traits, was determined using appropriate procedures within the SAS statistical program. High
statistical significance of all factors included in the model was established (p<0.001). Cows achieved the highest daily milk yield if they calved during the spring season, in their third lactation and in the interval of the second stage (61-120 days) of lactation. Milk yield decreased during the summer months from June to September. The fat content was the lowest in cows which calved in the spring season, during the first
lactation and the first stage of lactation (<60 days), it was lower during July, August and September compared to the month of June. During the summer, the protein content decreased from June to August,
while it increased in the subsequent stages of lactation. The stressogenic impact of the summer period on
milk production in cows is present every year to a greater or lesser extent, depending on a combination of several factors. Research confirms that the risk of heat stress, in addition to the summer period, is often
present from April until October.

AB  - The research was conducted on 175 cows of the Holstein-Friesian breed
that were selected as bull dams and achieved 400 lactations.
Animals are reared on 5 farms of the "Belgrade" Agricultural Corporation. Bull
dams are the offspring of 32 bulls calved between 2007 and 2014. The research
included the following characteristics of milk yield in standard lactation (305
days): milk yield (kg), milk fat yield (kg), milk fat content (%), protein yield (kg),
protein content (%). The variability of traits and the influence of factors (farm,
lactation in order, season and year of calving, bull-sire) were evaluated by the
method of least squares using the GLM (General Linear Model) procedure in the
SAS software package. The average milk yield of bull dams is 9617.11 kg, with
3.44% milk fat and 3.21% protein. The average yield of milk fat and protein is
329.56 kg and 308.65 kg, respectively. The largest positive deviation of milk yield
from the general average is 363.64 kg, while the largest negative deviation is -
1021.36. The largest negative deviation of milk fat yield and protein yield is -21.74
kg and -36.09 kg, respectively. The largest positive deviation of milk fat yield is
18.35 kg and protein yield is 9.46 kg. The influence of the farm is present in the
variability of all the observed traits of milk production except milk yield. Lactation
in turn had a statistical effect (p<0.05) on all traits included in the research, except
for protein content. The influence of the calving season is present in the variability
of milk yield and protein yield, while it had no effect on the other traits included in
the research. Calving year statistically (p<0.05) had a significant effect on the
variability of all observed milk yield traits. The sire bull influenced the phenotypic
expression of milk yield traits, while his influence on the variability of milk fat and
protein content was not significant.The results of the research indicate that the
established variability of milk yield traits in the population of the Holstein-Friesian
breed provides enough room for their further improvement through selection.

which were not published in journals and symposiums proceedings that consider
indicators of welfare and stress of the animals on cattle and pig farms intending to
improve their health and productivity. These indicators were created mainly as
results of research in numerous national and international projects. Mentioned
projects consider key indicators and prescribe on-farm assessments of animal
welfare and stress in cattle and pig farms. In the assessments of the welfare and
stress of the animals in different systems of keeping and accommodation, the need
to determine new welfare and stress indicators on cattle and pig farms was
observed. The publications about plans and programs, instructions,

AB  - In recent times, there has been a revived interest in utilizing medicinal
and aromatic plants (MAPs) for the treatment of diseases and enhancing the
productivity of farm animals. Thanks to their bioactive compounds, MAPs can
enhance the immune system, reduce the risk of disease and improve overall health
and welfare. This is especially important in the post-antibiotic era, where the search
for alternative options is becoming increasingly urgent. Although the mode of their
action is still unclear, today it is known that MAPs can modulate the microbiota
and promote gut health, leading to improved digestion and nutrient absorption.
Some components of MAPs act against viruses, bacteria and parasites. Additionaly,
the use of MAPs in livestock farming can also have environmental benefits.
Livestock methane emissions are a significant contributor to greenhouse gas levels.
Recent studies have shown that certain bioactive compounds found in MAPs could
inhibit methanogenesis and reduce the number of methanogenic microbes in animal
gastrointestinal tracts. As a result, researchers are exploring the potential of MAPs
in methane reduction strategies. Plants could also play a prominent role in
obtaining functional and enriched foods to contribute to animal product quality and
human health in general. This review highlights the importance and potential of
using medicinal plants in farm animal breeding, particularly in the context of the
One Health concept, which acknowledges the interconnectedness of human,
animal, and environmental health.

AB  - The study aimed to determine the effect of different fixed factors (breed, region, calving year,
calving season, parity and lactation stage) on daily milk production (yield and content) of four
dairy cattle breeds under the heat stress conditions (THI≥72). The research was conducted
on a set of test-day records of four dairy cattle breeds (Simmental, Holstein-Friesian, Red
Holstein and Brown Swiss) reared in the Republic of Serbia (Region of Mačva, Podunavlje and
Šumadija). The statistical analysis included test-day records collected in the period from the
beginning of the year 2012 to the end of the year 2019. Based on the performed analysis, it
could be demonstrated that all the effects included in the statistical model (breed, region,
calving year, calving season, parity and lactation stage) statistically highly significant (p<0.001)
affected daily milk production (yield and content) of cows reared in the terms of the heat stress
conditions. The highest daily milk production was determined in the region of Podunavlje, and
by the Holstein-Friesian breed. Furthermore, dairy cows calved during the spring season, in the
third lactation and from the 61st to the 120th day of lactation, had the highest milk production
during the summer period in an environment characterised by heat stress. Also, daily milk yield
of cows in a heat stress environment decreased in the period from June to September. The
results obtained indicate different animals’ responses to heat stress concerning the animal’s
breed, rearing region, calving year, calving season, parity and lactation stage.

AB  - Contact with a breeder is extremely important for the welfare of calves in the first month of life. 
In the intensive way of raising cattle, it is increasingly difficult to establish a good relationship
between breeders and animals. The authors defined 12 criteria for assessing animal welfare, 
which they classify into four groups, one of which is good behaviour in terms of social and other 
forms of behaviour and a good human-animal relationship. This implies the absence of fear 
because fear is an important animal welfare problem. The attitude of farmers towards calves in 
the first month of life was examined on two farms with an intensive production system. The 
relationship of humanstocalves was assessed using the test of approach and touch. Farmers 
competence assessments on the surveyed farms were satisfactory. It is characteristic of both 
farms that breeders who handle calves do not have a formal education in the field in which they 
work. Accordingly, their knowledge and skills are based on many years of work experience.The 
approach and touch test indicated a positive relationship between breeders and calves. The 
largest number of calves allowed approaching 1 or 2 steps, and a significant number also allowed 
touch, while a negligible number of calves avoided eye contact, as the most unfavourable type of 
contact.

AB  - Calcium and phosphorus represent very important nutrients
when it comes to poultry diet formulations. In this paper, we will briefly discuss
the relevance and nutritional requirements of these minerals in poultry feedstuffs as
well as the average amounts in poultry feed commercially sold in the Serbian
market. A total of 1,058 samples of standard complete feed mixtures for broilers
and laying hens were collected from the Serbian market, produced by the four
major Serbian manufacturers (I-IV) of animal feed over a period of five years
(2017-2021). The samples were classified into five groups: broiler starter feed (n =
198) - SF, grower feed (n = 239) - GF, and finisher feed (n = 204) – FF; layers feed
1 (n = 204) – LF1, and layers feed 2 (n = 213) – LF2. This research suggests that
the mineral composition of poultry feed is highly variable among manufacturers,
but also among the batches of the same manufacturers. All manufacturers for the
analyte in focus had values for certain batches that were outside the limits set by
the Rulebook. In general, the results of our research indicate that the average
content of total phosphorus in feed for broilers and laying hens in Serbia was
mostly close to the minimum-to-mid value of the defined (and declared) range of
permitted concentrations by the Rulebook, while the calcium content was
predominantly close to the maximum-to-middle value. Based on the results of this
study, it is recommended that feed manufacturers more frequently conduct an
external analysis of samples of feed components and poultry feed products for the
composition of these nutrients. Quality control of animal feed could be advised for
poultry farms as well in order to make sure that the feed is actually within the
parameters given by the manufacturers’ declaration.

AB  - The objective of this research was to study phenotypic expression and factors that can affect 
milk yield traits in the population of Simmental cattle breed in the Republic of Serbia. The 
research was conducted on a set of data that included records on the production and origin of 
Simmental breed cows displayed both in regional and municipal exhibitions in the territory of 
the Republic of Serbia in the period from 2004 to 2017. A final data set included records on 
production and origin of 1176 Simmental breed cows. The animals were raised in the area 
covering 9 regions of the Republic of Serbia. The research included most important milk 
yield traits in standard lactation: milk yield, milk fat content, milk fat yield, yield of 4% fat corrected milk (4%FCM). An average milk yield in studied population accounted for 
5.520±919 kg, milk fat content 3.94±0.11%, milk fat yield 218±38 kg, while the yield of 4% 
fat-corrected milk accounted for 5.474±933 kg. It was determined that region, age and 
lactation had a very high statistically significant effect on studied traits while the age of cows 
had no statistical effect.

AB  - In the last decades, there has been a trend present in the world to increase the size of dairy herds while increasing the yield of milk per head. In addition to environmental and economic benefits, this trend carries certain risks for the welfare of cows because in conditions of increased agglomeration of cattle the possibility of spreading of pathogens is also increased, there are less opportunities for adequate control and cows are exposed to greater selection and production stress. Research of the relationship between herd size and welfare quality parameters is still not sufficient to make relevant conclusions. Starting from that, the aim of this study, conducted in Serbia, is to examine the influence of herd size on parameters related to providing good feeding and housing conditions as important segments of the overall welfare of dairy cows. The assessment of given welfare parameters was done by Welfare Quality® Assessment Protocol for Cattle (2009) on 16 dairy farms of different herd sizes (large, medium and small) and housing management. The results indicate that there are significant variations in welfare indicators in each of the observed groups, which is why the size of the herd cannot be taken as a parameter that explicitly determines the quality of welfare. However, individual observation and comparison of welfare parameters between groups indicate that small herds in our production conditions could be identified as the greatest risks to the welfare of cows. In small herds, the highest share of cows of poor (4.62%) and fattened condition (8.76%) was found, as well as the lowest freedom of movement because cows on small farms are mostly reared in a tied system. Average values of indicators: lying down time (6.24s), frequency of collisions with equipment (13.25%) and high dirt contamination of cows (65.6-89.8%) further emphasize the issue of providing comfort in small herds.

AB  - The quality of farm animal welfare largely depends on a number
of measures and procedures carried out on farms, which are defined by one name
as biosecurity. The application of certain management practices differs from farm
to farm, and accordingly their impact on the quality of animal welfare differs. The
quality of biosecurity, welfare and the presence of factors that threaten them
depend on the technology of production on the farm, animal husbandry systems,
microclimatic and hygienic conditions, management, procedures performed on
animals and the way they are performed, the attitude of employees towards
animals, their training and competence, etc.The aim of this study was to determine
the impact of intensive calf rearing on differences in biosecurity and welfare
quality assessment on two dairy farms. The technological process of production on
both farms is similar, since both farms operate within the same production system.
On both farms, there is a nursery in a separate facility, but without individual
calving boxes. Calves are separated from their mothers immediately after birth.
One of the significant differences between the farms was the way the calves were
kept in the first 7 days of life. On one of the farms (A) the calves were kept tied in
the nursery, while on the other farm (B) they were housed in individual boxes, also
located within the nursery. At 8 days of age, calves were placed in group boxes, in
a special facility, rearing stable.
The greatest weaknesses and threats to biosecurity and welfare on both farms were
manifested at the earliest age of calves, and they relate to the accommodation and
feeding of newborn calves with colostrum. Determined that newborn calves were
kept tie-stall housing system or in dimly lit individual boxes of inadequate size and
design, housed in the nursery together with the cows. This increased the calf's
exposure to a number of pathogens. The risk to biosecurity and welfare is higher
when inadequate colostrum consumption is taken into account in terms of quantity,
manner and time of feeding. When it comes to calves of older categories, the
situation was significantly more favourable in terms of nutrition and housing
conditions, as well as health surveillance and provided great opportunities in terms
of further improvement.

AB  - The paper describes the effects of different rearing conditions as 
possible stressors on health, reproduction, growth, milk yield and quality of meat
and milk. It was pointed out that numerous internal and external factors of cattle
affect the physiological processes, health, reproduction, growth, milk yield and
quality of milk and meat as very strong stressors. They are especially important
when acting immediately after parturition, i.e. in the puerperium in cows and
immediately after birth in calves. In intensive cattle production, the most important
complex stressors regardless of origin, and physiological conditions in which these 
animals are more susceptible to distress are parturition, calf birth, puerperium,
intensive lactation, machine milking, oestrus, high pregnancy, dry period, 
grouping of animals, disturbed social relations, dehorning, castration, hoof
trimming, transport, sudden changes in microclimatic conditions and feed quality,
etc. Excessive disturbances before slaughtering cattle also cause a strong stress
reaction. In modern housing systems, animal disturbance, immobilization of
animals, restriction of movement, significant reduction of living space, strong
painful stimuli, dystocia, pain during uterine prolapse, castration and acute
inflammatory processes in the udder and uterus are also strong stressors.
Unfavourable social relations between animals in the group are usually very strong
stressors that lead to disturbances of their behavioural patterns. As a consequence 
of the action of numerous stressors, behavioural disorders, reduction of growth and 
milk production, the occurrence of metabolic and reproductive disorders, the 
occurrence of infectious diseases, reduction of meat and milk quality most often 
occur.

AB  - The experiment was set up to examine the effect of adding flax seeds to the cattle diet on the quality of meat, in the final phase of fattening. Thirty Simmental young bulls of uniform initial body weight were selected for the experiment and divided into 2 groups (CON (control) and LS (experimental)). The control group did not consume flaxseed as a dietary supplement. Flaxseed was added to the experimental group in the amount of 3.75% (300 g per day) of the concentrated part of the meal in the final 90 days of fattening. The research included the examination of certain traits of beef meat quality. The results of the study show that the addition of flaxseed in the diet did not have a statistically significant effect on pH, water binding capacity (WBC), weight loss during cooking and meat tenderness. The chemical composition of the selected muscles, as well as the content of total pigments did not change significantly in the experimental animals compared to the control group. It was found that the addition of flax seeds to the diet during the final phase of fattening had an effect on the colour change of the meat reflected in the brightness L* of the muscles of M. longissimus dorsi and M. semitendinosus.

AB  - Sodium chloride (NaCl) is one of the most important food additives and it has a significant impact on the sensory and microbiological properties of meat products. According to the Regulation on the quality of ground meat, meat preparations and meat products (Official Gazette of RS 50/2019), the salt content in meat products is not defined. The average NaCl values in these products can be concluded by comparison with available experimental and literature data. The aim of this study was to examine the content of sodium chloride in different meat products from 3 different production batches locally produced. A total of 42 samples were tested: Kulen and Čajna sausage (fermented sausages), dry tenderloin (cured meat products), smoked tenderloin (smoked products), hot dog (finely chopped boiled sausage), Serbian sausage (coarsely chopped boiled sausage) and pancetta (bacon). The highest average sodium chloride content was found in dry tenderloin (4.49g/100 g) while the lowest content was measured in hot dogs (1.88g/100 g). Comparing the obtained values of sodium chloride content with the values obtained by other authors for fermented products (Kulen and Čajna sausage), the tested products had significantly higher values of salt content, while the lowest average content of sodium chloride was found in smoked tenderloin samples. For other products, the content of the tested parameter was similar to the values reported in the literature. After the analysis of available samples, it was determined that the manufacturer adhered to the prescribed amounts of NaCl, according to the recipe, in every product. There weren't any notable deviations in the preparation of monitored meat products.

AB  - Cattle comprise a species of a domestic animal that is primarily bred for milk
production. The birth of a calf is the initiator for the lactation period and the sex of the calf can affect
milk yield. Additionally, a calf from a new pregnancy can affect the lactation from the previous
calving, since the mother gets pregnant and remains pregnant during most of the lactation, usually at
lactation peak. Therefore, the aim of this paper was to further investigate the possibilities of sexually
biased milk production of Holstein and Holstein crossbreed cows using data from the Republic of
Serbia. We also wanted to test the Trivers–Willard (TW) hypothesis that natural selection favors
unequal parental investment between daughters and sons under certain maternal conditions. At the
same time, this hypothesis assumes that mothers in good health and condition invest more in sons,
while mothers in a poor condition invest more in daughters. The obtained results deviate from the
view of the TW hypothesis because it was found that milk and fat yields in the first two lactations
were the highest in cows that had a female calf and were then pregnant with a second female calf
while the lactation from the previous calving was still in progress. We were the first in the world to
investigate the effect of the sex of calves at first and second calving on milk yield and fat yield in the
first and second standard lactation, depending on milk production levels on farms.
AB  - In order to examine the biased milk production depending on the sex of calves, data
on calving and milk yield characteristics of 15,181 Holstein type cows in PK Belgrade, Serbia were
analyzed. A total of 30,362 lactations that were realized in the period from 1985 to 2017 were analyzed.
Data were prepared and analyzed using the SAS software package (SAS Institute Inc. Software
License 9.3, 2012). The expression and variability of investigated traits were determined using the
PROC MEANS procedure, while the effect of individual factors on milk yield traits was analyzed
using the PROC GLM procedure. Obtained results deviate from the views of the Trivers–Willard (TW)
hypothesis. The results indicate that mothers invest more in female offspring by producing a higher
milk and fat yield in the first and second lactation compared to male offspring. This is especially
emphasized under better environmental conditions. The highest milk yield (7788 kg) and fat yield
(271 kg) in the second lactation were achieved in the combination with two consecutive female
calves in the group of higher-than-average milk production farms, and lowest in the combination of
two consecutive male calves (6783 kg for the MY and 243 kg for the FY), respectively.

abstract = "Cattle comprise a species of a domestic animal that is primarily bred for milk
production. The birth of a calf is the initiator for the lactation period and the sex of the calf can affect
milk yield. Additionally, a calf from a new pregnancy can affect the lactation from the previous
calving, since the mother gets pregnant and remains pregnant during most of the lactation, usually at
lactation peak. Therefore, the aim of this paper was to further investigate the possibilities of sexually
biased milk production of Holstein and Holstein crossbreed cows using data from the Republic of
Serbia. We also wanted to test the Trivers–Willard (TW) hypothesis that natural selection favors
unequal parental investment between daughters and sons under certain maternal conditions. At the
same time, this hypothesis assumes that mothers in good health and condition invest more in sons,
while mothers in a poor condition invest more in daughters. The obtained results deviate from the
view of the TW hypothesis because it was found that milk and fat yields in the first two lactations
were the highest in cows that had a female calf and were then pregnant with a second female calf
while the lactation from the previous calving was still in progress. We were the first in the world to
investigate the effect of the sex of calves at first and second calving on milk yield and fat yield in the
first and second standard lactation, depending on milk production levels on farms., In order to examine the biased milk production depending on the sex of calves, data
on calving and milk yield characteristics of 15,181 Holstein type cows in PK Belgrade, Serbia were
analyzed. A total of 30,362 lactations that were realized in the period from 1985 to 2017 were analyzed.
Data were prepared and analyzed using the SAS software package (SAS Institute Inc. Software

AB  - This study was carried to determine if dietary tryptophan can be beneficial for piglets in period of weaning. Trial was conducted
on 84 individuals (Landrace×Yorkshire) female and castrated male piglets, at 30 days of age, and of 9.78±0.42 kg. Test subjects
were penned into four groups and allocated to four different diets. This was done opposite to standard farm procedure; all
piglets penned in same group came from different litters. Animals were fed ad libitum for six days. Piglets in trial groups were
fed with basically same mixture with different levels of digestible L-tryptophan (0.1; 0.2; 0.3%). Productive performance (FCR;
ADG; ADFI) was calculated and behavior characteristics (postures, mounting, abnormal and aggressive behavior) were observed
using CCTV cameras. For the purpose of production performance analysis one way ANOVA was used while the Tukey test served
to determine the statistical significance of the differences between individual means values. Considering that there is no normal
distribution for behavioral parameters, we used non parametric Kruskal-Wallis test with multiple comparisons of mean rank
between groups. Productive results showed that control group had significantly better results for average daily gain compared
to all trial groups (p<0.05), other productive parameters didn’t show any significant difference. On the other hand, statistically
significant results occurred for two behavioral characteristics. Fighting differed significantly (p<0.05), during first day of weaning
between control and trial groups, intensive ear biting occurred at day two and three after weaning, and different significantly
on day three (p<0.05). According to our results tryptophan had no positive effects on productive performance (feed intake, daily
weight gain and feed conversion), but had some positive effects on reducing aggressive behavior. Conclusion could be that implementing
small doses of tryptophan on weaning can be beneficial to reducing stress and behavioral anomalies of piglets. Further
more extensive studies should be carried to verify these results.

AB  - Visual assessment and recognition of milk performance traits of cows are preliminary indicators of milk yield, longevity, as well as reproductive abilities of the animal, which is very important from the aspect of economy of milk production. Deficiencies in udder traits lead to poorer production, difficult milking and premature weaning of cows from the herd. The paper examines the frequency of desirable scores for a certain trait in first-calving heifers distinguished by way of keeping (heads reared by individual producers/holdings and heads reared on the farm) and by origin (domestic and imported animals), as well as the influence of these two factors on the observed traits. Five udder traits were analyzed: front udder length, rear udder length, rear udder height, central ligament, and udder depth on a total of 954 first-calving Simmental heifers. Observed by the way of rearing, higher frequency of desirable scores for all udder traits were achieved by cows reared on the farm, while according to the origin of cows, higher frequency of desirable scores for all udder traits was achieved by imported cows compared to domestic cows. The influence of factors of housing/keeping and origin, examined by χ2 test on all examined linear scores (frequency of scores) of udder traits was statistically very highly significant (p≤0.001), while the analysis of variance (F test) showed very high significance (p≤0.001) of interaction of origin and method of rearing on the traits of the central ligament and the udder depth, and significance (p≤0.05) on the height of the rear udder, however, no statistical significance (p>0.05) of this interaction was established on other linear scores of udder traits (length of the front and rear udder).

AB  - The body weight of calves in the earliest period of their life (age
from 0 to 7 days) is under the greatest influence of the farm and the season of birth.
The farm manifests its influence most often through the conditions of nutrition and
housing and the organization of the technological production process, while the
influence of the birth season is manifested through microclimatic and nutritional
conditions, as well. The most common deficiencies related to the nutrition of
newborn calves are related to: inadequate colostrum supply in terms of quality,
quantity and time of colostrum intake, which is closely related to the organization
of the technological production process on the farm. Dietary deficiencies affect the
body weight of calves at birth and at 8 days of age. In a study conducted over a
year (4 seasons), the colostrum diet of newborn calves of the HF breed on two
farms (A and B) with a tied housing system was analyzed. Calves were fed
colostrum on both farms at intervals, usually up to 2 hours, less often up to 4 hours
after birth. The colostrum consumed came from the mother, most often, and less
often from the other cow, while on one of the farms it was also used frozen.
However, the amount of colostrum consumed was deficient, it was 1-2 l on farm A,
and 2.5 to 3 l on farm B. The occurence of a deficient diet or other deficiencies in
the diet of calves was indicated by the average body weight, measured at birth and
at the age of 8 days. On farm A, a lower average body weight of calves (37.95 and
39.68 kg) was recorded than on farm B (40.00 and 41.80 kg) by age categories,
respectively. The average body weight of calves was statistically significantly (p
<0.01) influenced by the farm and the season of birth, as well as their mutual
interaction, but the effect of the farm was more pronounced.

39.68 kg) was recorded than on farm B (40.00 and 41.80 kg) by age categories,
respectively. The average body weight of calves was statistically significantly (p
<0.01) influenced by the farm and the season of birth, as well as their mutual
interaction, but the effect of the farm was more pronounced.",
