Abstract

Relevance. Rye occupies a special place among cereals as components of compound feeds. Rye, unsuitable for food purposes, but quite suitable for feeding farm animals, can be used for the production of compound feeds.Methods. To solve the problems, 4 groups of gobies were formed for rearing and 4 recipes of compound feed concentrates with different rye input rates were developed (0, 20, 30, 40%). The duration of the experiment was 135 days. To find out the effect of the compound feed composition on feed consumption, daily group feeding accounting was carried out. Experimental animals were weighed every 30 days, that is, monthly. To identify the effect of the tested grain (rye) consumption of the basic balanced diet, records were kept on the account of the feed consumed and their residues the next day. During the entire scientific and economic experience, feedabilitywas recorded.Results. Studies have shown that compound feeds prepared according to the developed recipes allow balancing the feeding of experimental bulls that will be raised to produce beef according to the detailed feeding standards available today, with a relatively low specific gravity of concentrated feeds. The inclusion of 20 to 40% rye in the composition of compound feeds does not reduce the balance of the diet of animals in the experiment. The gross increase in live weight and the increase per day in the experimental bulls of the first three groups did not differ significantly. Animals from group IV, which were fed compound feed with 40% rye, were inferior to control animals by 5.6 kg in total growth, in an average daily increase — by43 g. 5.87–6.03 ECU was spent per unit of live weight gain (1 kg).
