High-protein feed additives in the diets of young chickens

An alternative to scarce animal protein can be proteins of plant origin, in addition, they are considered hypoallergenic, nontoxic and easily digestible. Deep processing of peas allows you to obtain a protein concentrate with a crude protein content of up to 40% and a proportion of essential amino acids of 12.3% of the total protein. The inclusion of pea-based protein in the diet of birds can serve as a replacement for expensive imported soybeans. The experiment studied the effect of feeding feed additives based on extruded soybeans, peas and pea protein concentrate on the physiological state and productive qualities of young chickens. Studies were carried out on chickens (100 heads) of the Dominant breed meat -egg production direction. Control (1) group received commercial compound feed (PC) according to age, 2 group was administered equivalently in protein (up to 5%) pea protein concentrate (MCB) obtained by fermentolysis, 3 group - extruded soybean seeds (ES) and 4 group - extruded pea seeds (EG). Studies showed that young animals of group 2 receiving MCB had the best productivity indicators. Compared to the control, the increase in live weight in this bird on day 40 was 2.7% more (p ≥ 0.05), on day 60 - by 4.7% (p ≥ 0.05), the average absolute and daily increase was 5.4% and 10.2% (p ≥ 0.05). The obtained data are confirmed by the indices of massiveness and shortness, for 2 groups they were the largest and amounted to 5.7 and 53.8, respectively. In this group, the lowest feed consumption per 1 kilogram of live weight gain was noted, and the productivity index was 23 units or 19% higher. Biochemical studies of the blood of birds have established that feed protein additives of plant origin do not have a negative effect on the body of the experimental bird.
