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

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

Different liquorice’s dosage as additive to main diet influence on chicken-broilers quality and productivity is studied in the article. According to the results, it was established that liquorice addition use in chicken-broilers’ fattening diet during 42 days provided chick-en-broilers gain increase and fodder consumption decrease per 1 kg of the gain increasing, therefore, production economic efficiency

The article presents the data of liquorice fodder addi-tive use in chicken-broilers diet

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
