Abstract
Results of production traits obtained from first calving cows and evaluation of the breeding value of bull sires of Simmental breed in Serbia. Data was analyzed using the method of least squares and for evaluation of bulls' breeding value mixed model of random sire effect (BLUP method). Based on obtained results it was established in statistical analysis that breeding region had highly significantly affected (P<0.01) the deviation of production traits from the general average. Considerable deviation from the general average was caused by the year and season of calving (P<0.05), and interaction of breeding region and calving season contributed to high variation in yield of milk and milk fat (P<0.01).
Highlights
Cattle of Simmental breed, as the most present in Serbia, are mainly raised in semi intensive conditions of housing, care and nutrition, i.e. on small private farms with only few female heads of cattle
First calving cows raised in breeding region 5 produced by 514.2 kg and 4% FCM more compared to the general average, and even by 655.0 kg more milk compared to heifers which had calved in breeding region 8
Based on research results the following can be concluded: the systematic factors of the environment, breeding region, year and season of calving caused highly significant (P
Summary
Cattle of Simmental breed, as the most present in Serbia, are mainly raised in semi intensive conditions of housing, care and nutrition, i.e. on small private farms with only few female heads of cattle. More farmers – milk producers oriented towards the market have over 20 high quality Simmental cows. In order to be able to compete in milk production on the market it is important to continuously work on new.
