WEIGHT GROWTH OF DAIRY CALVES WHEN USING BVMK 60-10%
A rationally organized rearing of calves in the dairy period significantly affects the productivity and income of the economy. The use of feed additives to balance the diet for all nutrients is relevant. For research, 2 groups of heifers of pairs were selected according to the principle of analog pairs of 15 goals per group, taking into account live weight, date of birth, origin, age of mothers. Calves of the 1st group (control) were fed according to the feeding schedule adopted on the farm. BVMK 60-10% was used for group II calves mixed with concentrates, starting from 2 months of age and up to the end of the milk period in an amount of 0.5 kg / day. It was found that the use of BVMK 60-10% in feeding heifers leads to an increase in live weight during cultivation. So, in the heifers of the experimental group, the live weight at the end of the dairy period was 171.5 ± 1.28 kg, which is 14.0 kg or 8.9% more than in the control group. The final indicator for assessing the economic and useful qualities of animals is the profitability of the products. The calculation of the economic efficiency of growing calves in the dairy period showed that despite the fact that the total feed consumption in the groups where the calves were given a protein-vitamin-mineral supplement was slightly higher than in the control group, the cost of 1 centner of growth was lower, and the revenue from them implementations above. Revenue was more by 541.48 rubles. Profitability is higher by 2.0% in the experimental group, compared with the control group per head.
