Side products obtained during processing of many oil crops, have a high feed value and use in rations of animals and birds. The important thing in feeding poultry is protein nutritional value of forages and their biological integrity, expressed in amino acid composition. In this regard, there was a comparative analysis of the chemical and amino acid composition traditionally used in compound feeds for poultry, sunflower cake, and previously unexamined mustard protein-containing feed concentrate called "Gorlinka". During the research, it was found that the studied new feed additive is better comparing to sunflower meal, considering protein content and essential amino acids

This article presents the results of the impact of "Gorlinka" mustard protein-containing feed concentrate in the feeding of broiler chicken of the cross of "Cobb-500" on their performance and nutrient digestibility of the feed. The studies were conducted in the conditions of Krasnodonskaya Poultry farm in the Ilovlinskiy district of the Volgograd region. Full or partial replacement of sunflower meal with "Gorlinka" mustard proteincontaining feed concentrate in the feed mixture for the experimental broiler chickens contributes to the increase of the coefficients of digestibility of nutrients compared to the birds in the control group. The use of "Gorlinka" mustard protein-containing feed concentrate in the composition of feed for broiler chickens has contributed to higher coefficients of digestibility of nutrients: dry matter – 0.51-1,37%, organic matter – 0.6-1,99 %, crude protein by 0.8- 2,24 %, crude fiber – 0,34-1,65 %; crude fat – 0.94- 2,29%, compared to the birds in the control group. Nitrogen balance was positive in all groups; the use of nitrogen from the accepted experimental broiler chickens was higher in the experimental groups than in the control by 2.89-of 7.93 %. The use of nitrogen from digested nitrogen was higher in the experimental groups in comparison with the analogues from the control group by 2.65-of 7.97 %. The use of calcium and phosphorus by poultry was also higher in the experimental groups

This article presents the results of using "Gorlinka" mustard protein-containing feed concentrate, instead of sunflower meal in the feeding of broiler chickens of the cross of "Cobb-500". The studies were conducted in the conditions of Krasnodonskaya Poultry farm of the Ilovlinskiy district of the Volgograd region. Replacing sunflower meal with a product of processing of oilseeds which is "Gorlinka" mustard protein-containing concentrate, in the feed mixture in the experimental broilers had a positive impact on the productivity, physiological state of the birds, product quality and economic performance. The use of this mustard protein-containing feed concentrate in feeding of meat birds contributes to the increase of live weight by 3.46-of 6.65% and slaughter yield by 1.38-1.98% and improvement of quality indicators of the carcasses. Morphological and biochemical parameters in experimental broiler chickens in all the groups were within the physiological norm, which indicates a normally occurring redox processes in the poultry organism. However, adding "Gorlinka" mustard proteincontaining feed concentrate into experimental feed for broiler chickens contributed to the increase in the content of total protein, calcium, phosphorus in blood serum in comparison with analogues from the control group that received sunflower cake. As a result of the research, the economic effect in the experimental groups was up 710,40-1085,53 rubles
