The article presents an analysis of the influence of genes MС4R and POU1F1 on backfat of pigs. Shows the frequency of alleles and genotypes for genes MС4R and POU1F1 and their relationship with the parameters of backfat
On the basis of studying of collection of sorghum, the samples with important signs and properties for use in selection are marked out. Sterility fixers are defined as a result of studying of the samples on CMS, and sterile lines with the high combined ability are created
The article presents the indicators of the protective afforestation in Voronezh region, biometric growth index, agricultural and environmental impact of forest belts, efficiency of agro territories
In the article, there were determined the physiological parameters of resistance of stocked plants to in-creased pH soil. There was shown, that the resistance of apple-trees to the action of edafic stress-factors achieved in the case of their grafting on average-growing clone stock MM 106
Developed modes of increase of fertility of soils in local scales introduce the significant concern at cultivation of a planting stock of stone crops. Methods of local action have longtime phase and a positive effect in nursery gardens. Application of such measures in soil-amendment system of farming agriculture is possible
In the article, the results of researches on influence of various agrotechnical receptions on prod-uctivity and quality of a winter wheat on a cornon-grain predecessor are resulted
The article contains dynamics of selective and continuous cutting in oak forest of Russian European part at the last 50 years and analyzes their pathological effectiveness
During experiments on quail it was found that use of Trilaktobaktis probiotic is characterized with the activation of major types of metabolism, including protein –by increase the total protein content (5.17%) and mineral – by increase serum calcium and phosphorus (2.71 and 19.5%, respectively); by decrease of cholesterol content (10.6%). Probiotic stimulates erythro and hematopoiesis in quail: increase of the number of erythrocytes by 2.93% and hemoglobin by 2.57% was marked. Preparation enhances nonspecific resistance by increasing lysozyme and serum bactericidal activity by 47.4% and 149.6%.Besides, use of Trilaktobaktin diets increases digestibility of organic substance (5.74%), raw protein (3.95%) and raw fiber (4.83%). Probiotics use in the diet of quail improves nitrogen digestion by 5.3%, calcium and phosphorus – by 1.4%. Under the influence of probiotics content of lactic acid bacteria and bifidobacteriain chyme of quail increases by 46.2%.Use of Trilaktobaktin quail breeding increases safety and live weight gain by 6.0% and 6.9%, reduces the cost of feeds to produce 1 kg of body weight by 7.4%, and carcass yield reaches 66.4%, providing 100% output of first category carcasses. Use of Trilaktobakt feed additive has a positive effect on the quality of meat products. Thus, carcass output was 57.1% and the amount of fat decreased by 14.4% (pectoral muscles) and 12.7% (leg muscles) relative to the control. At the same time protein content in the thoracic and leg muscles increased by 7.5% and 10.7%
In the article we have studied 55 aboriginal varieties,
collected in the North Caucasus. We have described
allelic diversity and identified four haplotypes. All the
populations were closely related while being examined
using a factor of Nei's genetic distance (Dn), with the
exception of indigenous varieties of Armenia.
Maximum differences have been found between the
Uzbek population and Astrakhan, Turkmenian,
Armenian populations. The most genetically rich were
the population of Don area and Krasnodar region
The author has studied the efficiency of diets with NATUPHOS 5000 enzyme preparation. Adding the enzyme preparation into the mixed fodder for chicken broilers favors increase of live weight by 4,5 % and average daily weight gain by 6,1 %
