IMPROVEMENT OF THE TECHNOLOGICAL SOLUTION OF THE ELEMENT OF HEIFERS GROWING CULTIVATION OF THE CHIPS OF THE COLOSTRIC-PREVENTIVE PERIOD

Abstract

all experimental groups had a greater absolute live weight increase than the heifers in the control groups. A similar pattern was observed for the growth rate of heifers. Thus, the average daily gains of body weight in the experimental heifers, which were kept in cages on deep straw bedding, were: the first series 800 ± 50 g, the second – 900 ± 30 g, the third – 1020 g, the fourth – 1120 g, the fifth – 1220 g, whereas in the control group, respec-tively: 600 ± 55 g, 600 ± 35 g, 680 ± 35 g, 560 ± 35 and 640 ± 35 g (p≤ 0.001 in all cas-es) in favor of the animals of the experimental group.
