AB  - The aim of the research was to determine whether the frequency of certain injuries and diseases of cows as important parameters for ensuring their welfare varies considerably depending on the growing season (summer/winter). The research was conducted by Welfare Quality Assessment Protocol for Dairy Cows (2009) on total of 16 dairy farms (N=4.833 cows), wherein the provision of good health was descriptively categorized as unacceptable, acceptable, enhanced and excellent, according to calculated score (0-100 points).The air temperature of given location was recorded during each farm visit, so the average temperature of conducted assessment for specific season, served as additional indicator of dairy cows’ thermal comfort. The results of the study showed that the effect of the season on the incidence of injuries and illness was not significant (p> 0.05), but certain disorders were more frequent in one of the seasons. In the summer season, mastitis (2.63%), diarrhea (2.31%), discharge from the eye and nose (6.24% and 1.69%) were more frequent, and in the winter season lameness (27.78%) , tachypnoea (0.13%), and vaginal discharge (1.73%). Relying on welfare standards, it can be concluded that the parameters tested do not represent an alarming risk for the welfare of raised animals with the exception of mastitis rates and ocular discharge in the summer period. However, the overall health of dairy cows in both seasons is considered acceptable (in average 40 from 100 points) indicating that only minimal requirements for ensuring well-being are met and that there is a need to improve the health situation. Given that related studies have shown a low level of protection of the comfort of the examined animals as well as its significant influence on the provision of thermal comfort and health of cows, the recommendations are directed primarily at ensuring appropriate conditions of keeping with adequate and continuous health control of the herd

AB  - Assessment of cows' exterior is important because of the assessment of the capability of animals to guarantee, through their overall exterior appearance as well as the appearance of certain parts of the body, not only their good health but also long production life (longevity). The main goal of measuring of domestic animals is to determine the body dimensions, to compare animals of the same or different species, to understand the numerous physiological and biochemical processes that occur in the animal organism. Only by measuring, the accurate and reliable data on the general physical development of the animal and the harmony of its structure are obtained. In the present study, most of the physical measures were taken on total of 954 animals. The average height of the cow of the Simmental breed was 141.95 cm, the length of the pelvis was 51.44 cm, the width of the pelvis was 50.45 cm and the body depth was 78.84 cm. By analyzing the impact of the unified factor of the rearing system and origin, its very significant influence (p <0.001) was determined on all four properties of body development

AB  - There are numerous methods for decontamination of animal feed, and a relatively inexpensive method is the application of inorganic adsorbents. Adsorbents from the group of alumosilicates are particularly important, especially bentonite. Inorganic adsorbents are able to detoxify foods contaminated with mycotoxins by their adsorption power, while minimizing the negative effects on the organism.
The aim of this study was to examine and determine whether the use of natural bentonite has an effect on adsorption of aflatoxins from food. The influence of daily intake of bentonite at different doses (30 and 50 g / head) on the content of aflatoxin M1 (AFM1) in milk of examined cows was examined. By mycotoxicological analysis of the feed it was determined that maize grains were infested with aflatoxin B1 (1.24 μg/kg) and that this was the cause of the AFM1 metabolite in raw milk of cows. Based on the results obtained, it was concluded that the content of AFM1 in milk of cows consuming food with a daily intake of 30 and 50 g bentonite was significantly reduced.

AB  - The data of the Institute for Animal Husbandry, Belgrade-Zemun have been used to investigate the variability of the properties that are observed in the progeny testing of Simmental bulls. The analysis is based on a sample of 7,845 first-calving heifers in the period 2007-2010. The tests included the following milk properties in the standard first lactation (305 days): milk yield (kg), milk fat content (%) and milk fat yield (kg). An analysis of the production traits of the first-calving heifers under control showed that their average milk yield was 4346.49 kg milk with 3.93% milk fat and yield of 171.11 kg of milk fat. Sires, years and calving season exhibited a highly significant impact (p<0.01) on all the milk properties observed in the progeny testing. Based on the BLUP solution, the rank of bulls for each trait was formed, and then the correlation coefficients of the rank, ranging from 0.402 (relationship between the yield of milk and milk fat content) to 0.989 (the relationship between the yield of milk and the yield of milk fat) were established.

AB  - The study, which included 9 Holstein-Friesian bulls from the Livestock Center of the PKB Corporation, analyzed the impact of the ejaculate collection season on certain semen properties (ejaculate volume, sperm concentration, sperm motility in native ejaculate, sperm dilution, number of doses of one ejaculate and mobility of spermatozoa after thawing). For the purposes of this analysis, data for the three-year (2011-2013) and one-year period (2014) were used. In the three-year period, based on 621 ejaculates of three bulls, the average values for examined properties were calculated and the season's impact on these properties analyzed. The results show that the ejaculate collection season had a very significant effect (p<0.001) on the sperm motility in native ejaculate, and a significant effect (p<0.05) on the level of dilution of ejaculate and the mobility of spermatozoa after thawing. In the single-year period, based on 326 ejaculates from 9 bulls, the average values of the studied properties were calculated, and the influence of the season was also analyzed. The ejaculate collecting season showed a very high impact (p<0.001) on the mobility of spermatozoa after thawing, but no significant effect was found on other properties (p> 0.05).

AB  - To test the variability of fertility traits of Holstein-Friesian bulls monitored in progeny test, reproduction data of 342 cows, daughters of 15 bulls were used. Cows have been in production in seven farms of Agricultural Corporation "Belgrade" in the period from 2004 to 2012. The study included the following fertility traits: the average calving age, service period and calving interval. To analyze the influence of genetic and non-genetic sources of variability a mixed model with random effect of bull - sire, the fixed effects of farm, year, season and order of calving was used. The sire is present in variability of all the observed fertility traits (p <0.01), whereas the fixed factors manifested their influence at different levels of statistical significance. The heritability of fertility traits was low: the average calving age – 0.224, service period – 0.087, calving interval – 0.085. Repeatability of mentioned traits was 0.258, 0.111, 0.102, respectively.

Repeatability of mentioned traits was 0.258, 0.111, 0.102, respectively.",

AB  - Busha is small body native breed. It is found where the economic conditions are modest, and agriculture extensive. The intensification of livestock production, and the introduction of more productive, specialized breeds, caused diminished interest in growing Busha. Thus, Busha, as cattle oftriple productive properties, is largely suppressed, so that today we can rarely find examples of the pure breed. To protect specific geno-fund of this breed, the assessment of the level of endangerment of Busha population was carried out, which pointed to the risk status of the population and the necessity of the implementation of conservation programs. The paper analyzes the characteristics of physical development 138 Busha cows in the area of Pirot District, and the influence of non-genetic factors (farm, calving year, calving season) on the variability of traits. The average body weight of Busha cows in the area of Pirot District was 226.07 kg, height at withers 104.33 cm, rump height 104.12 cm,pelvis width 32.52 cm, chest depth 53.97 cm, chest circumference 130.48 cm and body length 119.67 cm. The analysis of the impact of non-genetic factors, showed a highly significant effect (p <0.01) of the farm on all the traits except the width of the pelvis, year of calving exerted a significant effect (p <0.01) on all traits of body development, whereas the calving season exerted no influence (p> 0.05) on any of the seven traits that have been studied.
