Sažetak
In a field of operation of Veterinary Ambulance Farkaševac farmers are mainly breeding Simmental cattle, followed by the number of Black Holstein and the Red Holstein used for crossing with Simental breed. The selection of bulls for the artificial insemination of cows and heifers in 2014 and 2015 in the field of operation of Veterinary Ambulance Farkaševac shows the interest of the cattle breeders for the bulls that have the best milking index. Such a unilateral selection of bulls for a well-adapted combined Simmental breed points out the shortcomings of selected bulls with a weak index of meat or legs. With such approaches in the second or third generation, the female calves will become good dairy cows, but will have weak legs and reduced longevity. In the case of male calves for fattening, due to poor meat index, such calves will not grow for 15 to 16 months in quality fattening steers, which will ultimately prolong fattening, increase production costs and reduce the quality of meat on slaughter line.
