Zootechnical and economic assessment of Megabust Rumen use in diets of high-producing cows

The effective implementation of the genetic potential of animals is impossible without improving their feeding. The article presents the main zootechnical and economic results of research on the use of the activator of cicatricial digestion «MegaBust Rumen» in the diets of down-calving and dairy cows. The effect of two dosages of the biopreparation (50 and 100 g per head per day) during the transition period and one dosage (100 g per head per day), the same for animals of experimental groups 1 and 2 - from 22 to 150 days of lactation, was studied. During the experiment, an improvement in the edibility of feed mixtures and the digestibility of nutrients was revealed in favor of cows of the experimental groups. Feeding of the tested drug resulted in an increase in daily milk yields by 7.9 and 10.9%, while reducing feed consumption for products and normalizing the reproductive abilities of animals. Taking into account the greatest increase in productivity and increased profitability of milk production, it is advisable to include the biopreparation in the amount of 100 g per head per day for three weeks before calving and five months after it in addition to the basic diet of cows with a milk yield of 9-10 thousand kg.
