This article presents the studying results of new premixes of domestic production using efficiency based on processed products, in particular - oil cakes. The research was carried out in the conditions of the second-order pedigree reproductor in LLC "Svetly" in the Svetloyarsky district of the Volgograd region in the period from 2015 to 2017. During the scientific and economic experience, the authors revealed the new fodder additives positive influence on the laying hens’ egg productivity, on the eggs morphological and incubation rates and on the got young birds. The use of premixes in layer diet, which included the fodder concentrate from the plant raw material "Sarepta" and Camelina seed oil cake, contributed to the increase in the hens laying capacity, in general, the group received in 249 and 310 pieces more than in the control one. The egg average weight from the chickens of the control group was 60.89 g; from the first experimental it was 61.33 g; from the second experimental it was 61.39 g, which was higher than in the control one, respectively, by 0.44 g and 0.50 g. While the hatching eggs morphological indices analysis, it was revealed that all parameters are within the permissible limits of the physiological norm. Fertilization of eggs in the control group was at the level of 89.33%, which is lower than in the experimental groups. As a whole, the eggs' production in groups was 20.00% in the control, 17.33% in the 1st group, and 16.00% in the 2nd test group

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

Modern commodity sturgeon breeding is one of the profitable and dynamically developing directions of fish farming in the Russian Federation. Only the system of Rosrybhoz has more than 40 enterprises of different ownership forms for the cultivation of sturgeons. In 2012, in agricultural farming of the Russian Federation we had grown more than 2.0 thousand tons of sturgeon. Crucial role to maintain normal functioning of the body of the fish when grown in closed recirculation systems plays complete and balanced nutrition. Proper organization of biologically full feeding of fish helps to maximize expression of their genetic potential. The article presents the results of the researches of the efficiency of using feed concentrate from vegetable raw materials called "Sarepta" in the composition of feed additives for 2-year old Russian sturgeons
