Currently, we are constantly improving the recipes of fish feeds, this reduces the cost of feed per gain, and it overall decreases cost of fish. We search for alternative cheaper sources of nutrients. Leftovers of vegetable oil and oil extraction industry such as oil cakes and meals have been used as high-protein feed additives for a long time. This requires a strict scientific control, precluding the possibility of their harmful effects on animal health. In this regard, there was a comparative analysis of the chemical and amino acid composition traditionally used in compound feeds for sturgeons of sunflower cake and feed concentrate from "Sarepta" vegetable raw materials. During the research it was found that "Sarepta" is better than sunflower meal considering protein and essential amino acids content

This article presents the results of the chickpea effect in feeding young and adult laying hens of "Hajseks brown" cross on their productivity and nutrient digestibility of feed. Studies have been conducted on the JSC "Agro-firm Vostok" in Nikolayevsky district of the Volgograd region. Complete or partial replacement of sunflower oil cake by chickpeas as part of feed for the experimental pullet hens improves nutrient digestibility coefficients compared with the control pullet group. The balance of nitrogen was positive in all groups, the use of nitrogen taken from guinea pullets was higher than in the control group at 0, 27-0,74%. Use of chickpea in the composition of feed for laying hens increases the digestibility coefficients of nutrients: dry matter - to 1,17-3,25%, organic matter - to 1,62-3,37% crude protein - to 0,45-1, 77%, crude fiber - to 0,72-1,05%; crude fat - to 0,35-1,55%, compared with chickens, hens in the control group. The use of nitrogen from the digested was1,37-2,13% higher in the experimental groups compared to analogs of the control group. The use of calcium and phosphorus for the formation of eggs was also higher in the experimental groups

This article presents the results of the chick peas use instead of sunflower cake, in feeding young and adult livestock hens-layers of the cross "Hajseks brown". The researches were carried out in the JSC "Agrofirm Vostok" of the Nikolayevskiy district in the Volgograd region. The sunflower cake replacement with legumes - chickpeas as the part of the experimental animal fodder for young and adult livestock hens-layers had a positive influence on productivity, physiological state of the birds, product quality and economic performance. Chick peas’ use in young hens feeding improves live weight at 1.03-4.68%, egg production in 0.99-4.7%, the average weight in 0.99-3.75% and eggs quality indicators. Morphological and biochemical indices in experimental young hens and laying hens in all the groups were within the physiological range, indicating normally occurring redox processes in the body of a bird. However, the chick peas’ application in fodder for experimental young hens and laying hens contributed to the increase of total protein, calcium, phosphorus content in serum compared with counterparts in the control group that received sunflower cake. As the researches result, the economic effect in the experimental groups was 833.01-3821.87 rubles

This article presents the results of the use of feed concentrate from vegetable raw materials called "Sarepta" in the amount of 5, 7.5% and 10% by weight of the feed, instead of sunflower meal in the feeding of Russian sturgeons. Studies have been conducted among 3 year old Russian sturgeons in the conditions of PRIBOY company in the Bykovsky district of the Volgograd region. The experiment lasted 24 weeks. Replacing sunflower meal with a product of processing of oilseeds - feed concentrate Sarepta, made from vegetable raw materials, in the composition of feed for sturgeons had a positive effect on live weight, absolute, average daily and relative gains and costs of feed. The use of "Sarepta" feed concentrate, made from vegetable raw materials in the feeding of Russian sturgeon contributes to the increase of live weight of 3.1-6.0 per cent, an absolute increase of live weight by 5.07-9.82 percent, and average daily and relative body weight increase. It was also found, that we had a decrease in feed consumption during the period of experience in the experimental groups. Morphological and biochemical parameters in experimental fish in all groups were within the physiological norm, which indicates a normally occurring redox processes in the body
