THE INFLUENCE OF NATURAL HAZARDS ON SOIL DEGRADATION AND AGRO-INDUSTRIAL ACTIVITY IN THE CRIMEA

The information of the impact of adverse natural phenomena related with the high temperature regime, deficit of precipitation and strong winds on the soil erosion, growth and yield of the crop. The status of shelterbelt, their ecological significance and the role of melioration and soil protection tillage systems in the Republic of Crimea are discussed

SPECIALIZED RAPESEED CROP ROTATION SEQUENCES IN THE STEPPE CRIMEA

The frequently changing market conditions of agricultural products require growing new and almost forgotten crops. Winter rapeseed is one of them. In the last decade its growing areas were increased to 14.000 ha on average, and in some years (2008) they were 30.000 ha. The main way to receive high yield of winter rapeseed in the Crimea is its proper place in the crop rotation sequences. The article gives the results of the study of winter rapeseed and wheat in the four specialized crop rotation sequences, where the rapeseed was sown in the bare (‘black’) fallow land and fallow winter wheat, and the wheat was sown after rapeseed, bare (‘black’) fallow and fallow wheat. The conducted analysis of weather conditions of the years showed, that during presowing and sowing periods there was the least amount of precipitations and it didn’t allow receiving the timely germination of rapeseed. The studying ancestors affected on the productivity of all crops participating in the crop rotation sequences. The rapeseed productivity during two crop rotation sequences (bare fallow) was 2.23 t/ha on average, but it was 1.60 t/ha in the direct reseeding. The productivity of the winter wheat sown after the rapeseed depended a lot on the ancestor: after the fallow rapeseed it was higher than in the direct reseeding (8% on average); after the rapeseed, sown after the wheat it was lower than in the direct reseeding (3%)

Effect of antioxidants in a liposomal form containing organic iodine of the blood serum biochemical composition and the structure of muscle tissue formation of young rabbits

The study of the effect of antioxidants containing organic iodine on the formation of the enteral environment of California young rabbits is described in the article. A significant increase in the level of thyroxine in the experimental groups was in the 2nd by 6.7% and in the 3rd by 8.9% (P<0.05). In the third group, there was a significant tendency to increase the total protein in the blood serum: compared with the control, it increased by 3.39 units (P<0.05). This trend continues in the level of albumin at 3.58 units. (P<0.05). There was a significant increase in creatinine in young rabbits of both experimental groups by 20.51-28.89 units (P<0.05). There was a significant excess of iodine content in the meat of rabbits of group 2 by 81.0 mcg (P<0.05), and in animals of group 3-by 234.1 % (P<0.05). There was an increase in the number of muscle fibers in both experimental groups by 68.0 and 78.0% (P<0.05-0.01). The diameter of the muscle fiber of experimental animals was significantly lower by 13.1 and 17.3 % (P<0.05). The animals of the experimental groups formed meat with a more delicate structure and an increased content of valuable parts-muscle and fat tissue

Mathematical methods in the breeding evaluation of small horned ruminants

Aim. Traditionally, prediction of breeding values of male small horned ruminants   (rams) by referring to levels of economically useful traits of their progeny is carried  out by methods of statistical analysis. However, at the same time, there is a forecasting method based on the use of a mixed biometric model. The solution of the system  of equations constituting a mixed biometric model is associated with certain difficulties caused by the peculiarity of the system matrix. It is proposed to use integrated  mathematical packages in the forecast, by which the system of equations can be  solved in several ways, followed by analysis of the results. The prediction of progeny  values is carried out by statistical methods using three statistical tests, as well as with  the use of a mixed biometric model. It is of interest to compare estimates obtained  by using statistical methods with estimates using a mixed biometric model. Material and Methods. The initial data set was the live weight of Qigai rams, the  progeny of a group of sixteen rams belonging to eight genetic groups.   Results. It was found that the forecast of breeding values of each animal using a  mixed biometric model substantially clarifies the rank of each animal in the group  being evaluated.   Conclusion. The refinement of the estimation of breeding value is related to the  effects of the genetic groups to which the animals belong in the mixed model, as well  as the degree of relationship between them. Also the mixed model also allows one to  isolate environmental effects from the overall assessment. Solving the system of  equations in several ways will improve the reliability of the forecast
