The aim of the study was to identify the GH/HaeIII gene polymorphism and to determine its association with growth traits in Salsk sheep bred in the Southern region of the Russian Federation. The identification of the GH gene polymorphism was performed by the PCR-RFLP method using the endonuclease HaeIII for restriction of an amplified fragment. During the experiment, the AA, AB, and BB genotypes of the Salsk breed sheep were identified at a frequency of 57, 36, and 7%, respectively. The values of the weight at weaning, at the age of 9 months and the average daily gain of the ram lamb with the AB genotype exceeded the values of the these parameters of the ram lamb with the AA genotype by 0.92 kg, 10.67 kg, and 47.3 g, respectively. The carcass weight, the weight of meat, the slaughter weight, and the slaughter yield of the ram lamb with the AB/GH genotype were found to be more as compared with the parameters of the ram lamb with the AA/GH genotype by 4.97 kg, 1.83 kg, 4.83 kg, and 2.04%, respectively. The ram's AB genotype also caused a greater weight of heart and kidney by 75.21 and 75.44 g, respectively. Thus, the presence of a heterozygous AB genotype in Salsk sheep breed has a positive effect on the growth traits. The rams of the AB/GH genotype significantly exceeded the rams of the AA/GH genotype and were found to have the best meat productivity. © 2017 Elsevier B.V.

Background and Objective: The aim of the work was to study the possibilities of intensifying the forage production on the basis of optimization of the cropland area structure of forage crops to provide the dairy cattle with feed in an unreliable moistening zone in the Russian Federation. Methodology: The optimal feed acreage structure, which was meant for the farm firms with intensive crop farming and dairy cattle breeding in the unstable moistening zone to be provided with their own field production forages, has been established. The optimization concept of the feed acreage structure, which was adapted to the zonal soil and climatic conditions, has been suggested. The concept is also based on the application of economically sound technologies of the fodder crop cultivation studied and on the methods of mathematical modeling in economics. The statistical result analysis was made according to the dispersion analysis. Results: The study has been determined that in unstable moistening zone, maize for silage, fodder beet, Sudan grass should be cultivated according to the intensive technology and medick to the extensive technology. For the intensive crop farming and dairy cattle breeding farm firms, the following fodder crop acreage structure is optimal: The maize for silage and soiling food take 33.0%, the annual grasses for hay and soiling food 33.0%, the perennial grasses for hay and soiling food 30.0% and the fodder beet 4.0%. This structure provides the maximum qualified net profit from 1 ha to110.2 € ha-1, the feed unit yield 4060.4 f.u. ha-1, with their prime cost 59.7 € t-1. Conclusion: The proposed integrated approach to optimize the cropland area structure of forage crops allows developing an economically sound structure of arable land for any agricultural enterprise that can ensure the maximum revenue per hectare. A differentiated approach to the cultivation technology contributes to improving the soil fertility, productivity and quality of agricultural production. © 2016 Ivan Fiodorovich Gorlov et al.

The effect of bentonite clay on the main fertility parameters of an ordinary chernozem has been revealed. The maximum contents of nutrients in the soil have been obtained after the application of bentonite at rates of 7.5 t/ha for nitrate nitrogen and mobile potassium and 10.0 t/ha for available phosphorus. At the application of bentonite at rates of 10.0-15.0 t/ha, the content of agronomically valuable soil aggregates resistant to mechanical impact has increased by 2.7%, while that of water-stable aggregates has increased by 6.8%. The portion of water-stable microaggregates has increased, which has decreased the degree of dispersion. Because of the increased content of fine-silt and clay particles, the portion of physical clay in the soil has increased by 3.13%, and the portion of physical sand has decreased. The optimum application rate of bentonite (7.5 t/ha) has been found, which ensures an increase in the yield of sorghum by 16.3%. Its effect was insignificantly lower than that of mineral fertilizers. © 2014 Pleiades Publishing, Ltd.

The aim of this study was to determine the associations between genotypes of the prolactin receptor gene (PRLR) and reproductive, growth, and meat traits in pigs. Genetic groups of sows were used: Large White (LW), Danish Landrace (LD), and Landrace × Yorkshire × Duroc hybrids (L × Y × D). Reproductive traits studied were the total number of born (TNB) and the number born alive (NBA). The growth traits were the number of days to 100 kg and the average daily gains (ADG). The meat traits were the average backfat thickness (BFT), half carcass weight (HCW), area of M. longissimus dorsi (MLT), and lean meat content (LM). The polymorphism was detected using the polymerase chain reaction-restriction fragment-length polymorphism (PCR-RFLP) method. It was found that the genotype BB is associated with the best NBA. In sows LD, the AB genotype is associated with best number of days to 100 kg; in hybrids L × Y × D, the AA genotype is associated with better meat traits as compared to the genotype BB. © 2014, Allerton Press, Inc.

The chemical equilibrium in the soil solution determines the dynamics of its material composition, migration and accumulation of salts. In the soil solution are formed electrically neutral ion pairs CaCo3°; CaSO4°, MgCO3°, MgSO4°, charged ion pairs CaHCO3 +, MgHCO3 +, NaCO3 -, NaSO4 -, CaOH+, MgOH+. The calculation method proposed for quantitative assessment of real ion forms in the soil solution of solonetz taking into account the ions association. Determination of real condition of the main ions in soil solution is based on ion association and its influence on physical and chemical properties of solution. Were calculated the free and associated ion form concentration according to analytical ion concentration. Were used an iteration to solve the equations of ion material balance, a linear interpolation of equilibrium constants, a Method of Ionic Pairs including a law of initial concentration preservation, a law of the operating masses of equilibrium system, the concentration constants of ion pair dissociation following the law of operating masses. Upon completion of iterative procedure, was determined the quantity of ion free form and a coefficient of ion association γe as the ratio of ions free form to its analytical content γe= Cass/Can. For calculation procedure were used the own software products. The association of ions varies in individual soils and soil layers, increasing the soil solution salinity amplifies the ions association. Depending on concentration and composition of soil solution the ionic pairs are: 15-45% Ca2+; 16-49% Mg2+; 0,6-8,4% Na+; 2,2-17,6% HCO3 -, 16-51% SO4 2-, up to 88% CO3 2-. The proposed thermodynamic calculation method for quantitative assessment of real ion forms in the soil solution helps to explain the evolution of salted soils, maintain the soil, improve plant nutrition and irrigation. © 2014 Science Publication.

The Melanocortin-4 Receptor (MC4R), a G-protein coupled receptor, is implicated in mediating the effect of leptin on food intake and energy balance. A previous candidate gene study reported an association between an MC4R polymorphism (Asp298Asn) and growth and meat productive traits of pigs. The aim of this work was to determine frequencies of the MC4R/Taq I genotypes and alleles in Danish Landrace (LD), Canadian Landrace (LC) and crossbred pigs Danish Landrace × Canadian Landrace (LD × LC) in breeding Cent "Plemzavod Jubilee" (Tyumen) Russia and to estimate their associations with some growth and meat traits. The polymorphism was identified by PCR-RFLP method. The traits studied were: Number of days to 100-kg, Average Daily Gain (ADG), Backfat Thickness (BFT), average daily Feed Intake (FI) and Length of Body (LB). In the all test groups we found a higher frequency of G allele (0.71) compared with the A allele (0.29). The results of present study suggest that the MC4R gene contributes to Days to 100 kg, ADG and BF. The heterozygous genotype AG was favorable in LD breed. The significant effects of-1.43 (LD male) and -2.81(LD female) for Days to 100 kg and of+61.17 (LD male) and +26.3 (LD female) for ADG were calculated. The homozygous genotype GG was favorable in crossbred LD × LC. The significant effects of +74.2 for ADG and-1.5 for BF were calculated. Therefore, the data support a role for the MC4R Asp298Asn polymorphism in the genetic basis of economically important traits in pigs of Russia. Further research is needed to determine the effect of this gene on growth, meat and reproduction traits in pigs of different breeds and crosses. © 2014 Science Publication.

Increasing unit capacities, in particular, of the wheel-mounted tractors upto 450-500 h.p. leads to a sharp increase in mass and hence to the excessive soil over compaction and reduction of yield along the tractor wheel track by upto 30%. The slipping of wheeled running gears up to 12-15% is noted, which results in actual rotary tillage of soil surface and the deterioration of particle size distribution of a production layer, and causes wind erosion. As compared to the track-type vehicles, the wheeled vehicles have a significantly higher design mass. Using tractors of classical design aggravates the maneuverability of a machine-tractor aggregate (MTA), and increases the width of a headland. A stepped track drive of a tractor doesn't contribute to the continuous full use of the installed capacity of an internal combustion engine (ICE). At present, the ecological balance of the technogenic processes in agrocenoses is provided by using the mobile power units of the fifth generation, the technical structure of which is based on the formation of multiprocess small-run MTA. According to preliminary calculations, the power units of the fifth generation reduce the number of technological operations by 40% as compared to the product complexes of vehicles based on the use of tractors of the fourth generation. Studies show that the ecological balance of the technogenic processes in the modern structural and technological schemes of tractors can be provided only if using the tracked vehicles of the fifth generation. © 2010 RJPBCS.
