In recent years, Russia has reached significant heights in scientific substantiation of the use of genetic potential of productivity of farm animals and poultry. For the effective development of industrial areas in the agro-industrial complex, it is necessary to work tirelessly to improve technological processes. Broiler chickens are raised in a short time, when the bird must maximize its genetic potential. The level and quality of protein feeding can have a significant effect on poultry productivity. Each element of feeding becomes an important link in the chain leading to high performance, so careful selection and optimization of rations plays a crucial role in increasing productivity and economic efficiency of poultry industry.
The research work is aimed at assessing changes in the biochemical profile and improving the productive characteristics of broiler chickens, while partially replacing the traditionally used soybean meal in their diet with a new feed component – lupine seeds treated by the barohydrothermal method (BHT). After BHT treatment, white lupine was additionally enriched with Saccharomyces cerevisiae yeast, what made it possible to effectively reduce the effect of anti-nutritional factors that adversely affect digestive processes, and at the same time increase the level of easily assimilated protein in the feed.
As a result of introduction of treated white lupine seeds into the diet of broiler chickens, a positive trend was recorded. In the first experimental group, tgere was an increase in the total protein content in the blood serum by 5.3%, while in the second group – by 3.4%. The average excess body weight of the experimental groups in comparison with the control group reached 12.7%. Substitution of 50% of soybean meal with lupin modified in this way promoted the activation of protein metabolism in the organism of birds, contributing to better expression of their genetic potential and providing higher live weight gain.
Keywords: lupine, barohydrothermal treatment, meat productivity, broiler chickens, feed yeast.
