COMPARATIVE ANALYSIS OF THE DE-FORMATION IN TIRES 30.5-32 WITH A DIF-FERENT INTERNAL STRUCTURE
05.20.00 Processes and machines of agroengineering systems
DescriptionThe objective of the research was to study the patterns of deformation with the different internal structure in a tire envelope with the standard size of 30.5-32 in propulsion units for modern mobile farm vehicles. The research method is experimental with the use of «a tire tester» and specially developed devices for determining the deformations of the tire envelope concerning the rim in circular and radial directions. Output indicators of a wheel with the pneumatic tire are determined by the ability of the tire to be deformed so that at small hysteresis losses in the rubber-cord envelope the largest area of the contact with a substructure have been created. This circumstance has special significance when developing the tires for mobile farm vehicles with the high power saturation, the patterns of deformation of which are poorly studied now. The analysis of the carried out experimental researches has shown the expediency of application of the experimental tires with the same standard size, offered in the work, on the propulsion units of the mobile farm vehicles instead of diagonal and radial tires. The rolling resistance of the experimental tires 30.5E-32 is lower than the rolling resistance of serially produced tires, and the developed area of contact is higher and that provides the decrease in the condensing impact on the soil

Description
The purpose of examining the roadside agrocenosis in the Aksai district of the Rostov region was a comparative assessment of the ecological condition of ordinary black soil and agricultural products grown in the technologically transformed conditions. The evaluation of agro-forestry factor impact on refraining toxic substances from the techno-genesis road source was also of interest. The study was expected to determine the actual and potential content of copper, zinc and lead in the ordinary black earth, as well as to evaluate the accumulation level of the investigated elements in the winter wheat grain. The potential reserve of investigated elements in ordinary chernozem (or black soil) is several times higher than the potency of the current content. Distribution of the results of the actual and potential reserve determination demonstrated the transfer of gas-dust emissions beyond the forest belt where the production crops are grown. At the remoteness point of 10 meters away from the road beyond the forest belt minimal amounts of actual and potential element content were found. At a distance of 50 - 100 m there was found a significant excess content of copper, zinc and lead. Repeated studies conducted 20 years later, identified the lead content in winter wheat grain exceeding the MPC. The results obtained have demonstrated the lack of agro-forestry effect in refraining gas and dust emissions by the road forest belt

COMPATIBILITY OF VARIOUS DOSES OF ECOVENTURA AND LIMESTONE IN FEEDING OF REPLACEMENT YOUNG DUCKS
06.00.00 Agricultural sciences
DescriptionThe research is aimed at studying the compatibility of different doses of ecoventura (TU 9283-199- 10514645-13) and limestone in the diets of rearing of ducks of "Blagovarsky" cross and the impact on productive performance. As a result of scientific and economic experience obtained data on the dynamics of live weight in groups of rearing ducks indicate that ecomentors in combination with limestone have a growth promoting effect and a positive effect on the growth of ducklings. Best growth depending on dose administration of ecoventura and limestone in feed composition had a rearing ducks III (ecomentors (1,0%) + limestone (3,0%) by weight of the feed) and IV experimental groups (ecomentors (1,0%) + limestone (3,5%) by weight of the feed). The results of the study measurements (body length, keel length, breast width, chest girth, chest depth) and indices stature (massiveness, the meat content, arizonia), which were higher in males and females when fed with mixed fodder with the introduction of ecoventura and limestone in an amount of 1.0 and 3.5% respectively. Introduction to feed composition of ecoventura and limestone in an amount of 1.0 and 3.5%, respectively had a positive impact on exterior indicators of rearing ducks

STATUS AND PERSPECTIVES OF DEVELOPMENT OF DAIRY CATTLE IN THE ROSTOV REGION
DescriptionIn this article we carry out the analysis of the current state of dairy farming in the country and in the Rostov region. The article shows the number of cows and milk production in farms of all categories in the country and the region. At present, Russia is ranked 6th in the world in milk production and is the largest importer of milk and dairy products. The situation is similar in the dairy industry of the Rostov region. Nowadays Rostov region ranks 5th in the Russian Federation and 2nd place in the southern Federal district in milk production. A large portion of milk (83,4%) is produced in households. This indicates decentralization of livestock complex in the Rostov region. The demand for milk is met through own production by 83%. Currently, the region has just started a period of stabilization of the gross milk production. For the last 4 years the indicators of milk productivity of cows have been 13.0-14.5% higher than the national average. Much of this was facilitated by the measures of state support. With the support of Federal and regional authorities in this field it has been created a favorable investment climate for the development of dairy farming. In the article the main organizational and economic aspects of profitability of milk production have been shown. It identifies the main issues that hinder the intensification of dairy farming. The dairy sector of the Rostov region has good prospects. Main approaches to the solution of the problems of development of dairy cattle breeding in the Rostov region have been listed

DescriptionIn the conditions of south zone of Rostov region it is more effektive to fertilize winter barley in the dose of N40P60K40, the yield of crop increasing by 47 53 percent compared with the control one and operating profit up to 3172-5579 rub/ha. Cultivating winter barley preference should be given to the kind Larets as being more high-yielding and economically more profitable.
