On the experimental field an experiment was laid to study the productivity of two types of winter vetch: Hungarian vetch (Vicia pannonica Granz) varieties Orlan and Chernomorskaya and downy vetch (Vicia villosa op Roth) varieties Lugovskaya 2 and Glinkovskaya. The vetch was sown in a mixture with winter wheat (Triticum aestivum L.) variety Tanya. Various doses of mineral fertilizers. Phosphorus (superphosphate) and potassium (potassium chloride) were introduced during sowing, nitrogen (calcium nitrate) – as early spring feeding. As a control, we studied the variety of furry vetch Lugovskaya 2, since this is the most popular variety of winter vetch in the Krasnodar Territory. The soils of the experimental plots are represented by leached, low-humus heavy loamy powerful chernozem. Due to the limited feed intake, the diets of high-yielding cows are rich in highly digestible non-structural carbohydrates (ADF), which fermentation leads to the formation of a large amount of propionic acid in the rumen with a strong acidic effect and, conversely, NDF fermentation is slower and on a smaller scale. The variant winter wheat Tanya + winter vetch Lugovskaya 2 - is closer to the optimum in the second cut. The rest of the experimental options of vetchwheat and vetch-triticale grass mixtures also have a negative fiber balance, which is not acceptable for feeding high-producing dairy cattle.

The article provides calculations and recommendations for fisheries development and improvement of fish productivity of reservoirs in the Kuban basin. The taxonomic composition of water biological resources has been studied and the natural bio-production potential of some reservoirs in the South of Russia has been determined. It is proposed for the purpose of pastoral aquaculture to produce directed formation of the ichthyofauna of reservoirs by yearlings Hypophthalmichthys molitrix, Hypophthalmichthys nobilis, Ctenopharyngodon idella, and as anaddition Cyprinus carpio, Mylopharyngodon piceus, Liza haematocheila with an individual mass not less than 25-30 g, which will allow rational use of forage resources of aquatic ecosystems.

Currently there are many known enzyme preparations, which to varying level of efficiency split non-starchy polysaccharides in mixed feeds. The research aims to study the consumer qualities of broiler meat and its dishes when included enzyme preparations Celloviridin G20x and Amilosubtilin G3x into diets based on wheat grain (40% by feed weight), barley (20%) and soybean meal (15%). The results obtained in the course of research were processed by mathematical analysis software package "Microsoft Excel". The best effect on the poultry slaughter qualities had joint supplements of multienzyme compositions Amilosubtilin G3x at a dose of 300 g/t feed and Celloviridin G20х at a dose of 150 g/t feed, which resulted in the superiority of chickens from the third test group over the control counterparts in weight of semi-eviscerated carcass by 14.5%, evisceratedby 15.1%, slaughter yield-0.66%. Chickens, which were fed the mixture of preparations, surpassed their control counterparts in indicators characterizing the ratio of edible parts to inedible by 32.03%. Use of enzyme preparations intensified protein metabolism in the poultry body, which contributed to improve the chemical composition and increase the biological value of meat protein. Due to this, in the femoral muscles the synthesis of dry matter and protein was more active, which in this muscle of broilers from the third test group resulted compared to the control in an increase of dry matter concentration by 2.674%, proteinby 2.587%. When studying the effect of heat treating chicken carcasses in the compared groups on the organoleptic characteristics, four samples of grilled chicken were cooked. The dish sample, the formulation of which included broiler carcasses of the third test group got top point total and surpassed the control counterparts in organoleptic qualities by 0.37 points. This superiority is provided, first of all, due to such parameters as flavor and tenderness.

Natural feed additive is made on the basis of bottom sediments of the steppe reservoirs of the Krasnodar Territory and is a dry powder of a grayish tint. Mineralization of local bottom sediments is 6.5 g / kg, calcium content is 29.7 g / kg, macronutrients from 1.04 to 25.8 g / kg, trace elements from 0.03 to 0.7 g / kg. The medium reaction is from neutral to slightly alkaline. Using sapropel feed additives (SFA), it was possible to increase the gross live weight gain of broiler chickens by 1.7-2.0% while reducing feed costs per 1 kg of gain by 0.5%. All internal organs of the poultry were developed within normal limits. There was profitability increase by 1.1% in growing broilers, when using sapropel feed additives in full feed. Blood biochemical values were at an optimal level. Therefore, this feed additive can be considered as a natural feed ingredient; however, it is necessary to further develop a complex feed additive from natural components that partially or completely meets the requirement of the poultry in biologically active substances and micronutrients.

The paper discusses the effect of a newly developed complex feed additive Grainbiosorb used in complete feed on livability, age of first egg laying, egg productivity, and feed consumption for the production of 1 dozen eggs of laying quails of the Texas white broiler breed. The scientific experiment was carried out in the experimental vivarium of Krasnodar Research Centre for Animal Husbandry and Veterinary Medicine according to the standard technique recommended by the Federal Scientific Center “All-Russian Research and Technological Institute of Poultry” of Russian Academy of Sciences, (Sergiev Posad, 2013). The developed complex feed additive Grainbiosorb consists of fermented brewer’s spent grain, a mineral sorbing complex and probiotic microorganisms. Brewer’s spent grain is pre-fermented with probiotic bacterial concentrate, consisting of lactic acid, and propionic acid microorganisms. The use of fermented brewer’s spent grain in combination with a mineral complex can solve the problems of metabolism, digestion, exposure to heavy metals and thereby increase productivity and contribute to obtaining safe poultry products. The livability of the quail population in experimental and control groups was the same and amounted to 90.0%. The quails of the first group laid the first egg at the age of 44 days, while the quails of the second group at the age of 42 days. Gross egg production for the period of the experiment per the initial laying quail and the egg production for the average laying quail increased in the experimental group relative to the control by 3.8%. The intensity of egg production in the experimental group increased by 2.3 abs. % relative to that in the control group. Feed consumption for the production of 1 dozen quail eggs decreased by 5.5% in the experimental group, relative to the control.
