Influence of keeping technology on the weight gain of the Aberdeen-Angus breed young animals in the colostrum period

In beef cattle breeding, unlike dairy farming, the only product is a calf. Therefore, industry's competitiveness directly depends on annual retention from each cow and heifer calf, preservation of calves, high growth energy young animal throughout rearing period. These indicators are influenced by many factors, one which breeding technology. The colostrum period most critical; newborn calves that do not receive adequate attention at beginning this die within first two days life or have retardation. Given this, it becomes urgent to establish level dependence between animals' technology keeping cows during studies were performed Aberdeen-Angus breed having problems in interaction due weak maternal instinct sucking reflex (problem pairs' cow-calf). rates bull-calves heifers studied: live body weight, average daily gains, absolute multiplicity weight gain. factor new technological element - transfer problem cow-calf into correction sections, period, further was analyzed. Our shown potential difference (P=0.999) bull-calves, transferred together with those for no sections used. advantage age 18 months 27% 28% favor transferred; they prevailed (P>0.999) 29% terms. When compared months, heifers, had been an 26%. gains these greater than transferred.
