DescriptionThis 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

DescriptionFerrourtikavit is a biologically active additive (BAA) derived from common nettle supplemented with micro nutrient elements (titanium, vanadium, molybdenum, zinc, copper, iron, tin, chromium, manganese, barium). Ferrourtikavit is manufactured from local vegetable raw materials, however its application in feeding dairy cows is not sufficiently studied. Therefore, the application of the BAA ferrourtikavit in animal feeding with a view to increase milk production is relevant. The aim of the research conducted is to investigate the impact of the BAA ferrourtikavit on the overall nutritional value of animal diet and reduction of food consumption. The experiment was conducted on four groups of black-motley breed dairy cows. Formation of the experimental groups (15 animals per each group) was performed on the third lactation, taking into account age, productivity during the previous lactation, breed characteristics, live weight. The main diet consisted of hay, haylage, succulent fodder, concentrates. Additionally to basic diet the 2nd , 3 rd and 4th experimental groups obtained the BAA ferrourtikavit at the doses of 0,25, 0,50 and 0,75 mg/kg of live weight, respectively. It has been established that the animals from the experimental groups (2nd, 3rd and 4th) consumed 43,9-51,3 energetic feed units less, 439,4-513,5 MJ metabolic energy less, 56,4 – 62,0 kg dry matter less, 1,1 – 1,6 kg digestible protein less. The lowest feed consumption was noted among the animals from the 3rd experimental group, in the basic diet of which the BAA ferrourtikavit in an amount of 0,50 mg/kg of live weight was introduced. The research conducted established, that application of the biologically active additive ferrourtikavit in the diet of lactating cows at the dose of 0,5 mg/kg of live weight led to the highest milk yields 4678±45,17 kg. In the experienced groups, increase in milk yields, decrease in concentrates' utilization as well as costs of 1 kg milk as compared to the control group were registered

DescriptionThe influence of the crop rotation type, predecessor and different doses of mineral fertilizers on the yield of two winter wheat cultivars (Lira and Krasnodar 99) was investigated. The investigations were carried out in the North-Kuban Agricultural Experiment Station in two five-crops: grain tillage and grain - grass tillage rotation of prolonged stationary experience. The soil is the black soil, low in humus, powerful, with humus content, depending on the power of nutrition backgrounds in the arable (0-30sm) soil layer is 3,95-4,00%, of mineral nitrogen is 5,9-8,3 mg / kg of soil, of exchangeable potassium is 330-360 mg / kg of soil. It was found that the maximum value of the winter wheat crop structure elements is noticed in the fertilizer systems with complete mineral fertilizer, and the minimum value - with PK and NK. Winter wheat yield depends on the crop rotation of 8-15%; from its predecessor - 15-18% and 27-31% of the fertilizer. Grain quality was generally determined by the dose of fertilizer. High and higher doses of fertilizers contributed to the protein content from 11.7 to 12.3% and fibrin content - 23,5-24,0%. A strong correlation between yield and agronomic methods was determined
