Use of feed additives “Valopro” and “Ruprokol” to increase the energy of growth and meat productivity of simmental steers

Abstract

The article assesses the growth, development and meat productivity of Simmental bulls during the growing period when the feed additives “Valopro” and “Ruprokol” are included in the ration. For experience in intensive growing conditions on the basis of the industrial complex LLC Agropark-Razvilnoye, Rostov Region, in September 2019, two groups of 10-month-old calves of Simmental breed were formed. In the experimental group, the calves were fed in feed compound “Valopro” at the rate of 20 grams and “Ruprokol” - 50 grams per head per day. Gobies of control feed additives were not received. In the experimental group, over 80 days of growing, an average of 9.15 kg was consumed, and in the control group, 8.9 kg of dry matter per head per day. The absolute growth of young animals fed a diet with feed additives was 26 kg higher during the accounting period. The use of fodder additives in the feeding of bull calves made it possible at the age of 13 months to obtain a live weight of 439 kg, one kilogram of which contains 403 g of muscle tissue and 429 g of edible carcass elements. The introduction of feed additives helped to reduce feed costs per 1 kg of gain in live weight by 18%, to obtain 1600-1700 g of daily gain and provide additional profit.
