【 摘 要 】

The feeding yeast, produced on a substrate prepared from the green mass of Sakhalin buckwheat, which hasbeen introduced to the Republic of North Ossetia-Alania, contribute to the better development of chickens,increasing their productivity and reducing the cost of production. Experimental studies have been held to determinethe effectiveness of yeast protein usage on broiler chickens. The research took place at a poultry farm in the RussianFederation, the city of Vladikavkaz. The research on Cross broiler chickens Ross 308 had been taking part during 56days. We have determined the effect of yeast protein on the growth and the development of broiler chickens. Wehave also revealed the superiority of live weight and livestock safety of broiler chickens which received yeastprotein in comparison with their control analogues that did not receive feeding yeast protein. The increase of liveweight in a bird that has received feeding yeast from Sakhalin buckwheat is explained by the higher value of theyeast cell protein. It is established that a green mass of perennial is a biologically valuable, environmentally friendlysource of production of a nutrient medium for growing yeast, it is high-yielding and not demanding to the conditionsof plants' cultivation. The authors have found that the muscle mass in the best experimental groups is – the 1-st andthe 2-nd-was 936.7g and 902.2g, compared to 785.4g in the control group, which is by 19.3% and 14.9% more thanin the control group. The ratio of muscle mass to bone mass in the control group was 2.55, compared to 2.73 and2.71 in the best groups (according to their live weight) the 1-st and the 2-nd experimental groups, which is 7.0 and6.3% more than in the control group. It has been found that the replacement of 5% and 3% of vegetable protein bythe yeast protein, produced on the hydrolyzate of the green mass of Sakhalin buckwheat is effective andeconomically feasible to be used in the diets of broiler chickens.
