We developed an effective technology of reproduction in meat cattle breeding, which allows rational use of the bulls-producers, to obtain a high output calves (85-95%), to organize the accuracy of the account of the origin of young animals, to improve the level of selection-breeding work on the improvement of productive and breeding qualities of animals and create in a shorter time highly productive herds of meat cattle
The article presents the study of carcass and meat quality of ST and DM-1 pig breeds, and the hybrids obtained with the participation of Landrace and Pietrain breeds. Crossbred gilts significantly superiors to counterparts in all parameters of meat performance
Based on the analysis of 422 samples of compound feeds and grain for processing of different farms of the Krasnodar region, we have established the level of their natural mycotoxin contamination and also identified prevailing combinations. Regularities of the frequency of contamination have been presented as well
In this article, the results of researches of the influ-ence of terms and norms of crops of a winter rape on growth and development of plants, winter hardi-ness and productivity of cultures in the changed environmental conditions of Rostov region are re-sulted
The results of long-term researches of studying the influence of salinity and alkalinity of soils on growth and efficiency of arable crops are noted in the article. Multistage diagnostics and comparative estimation of salt-endurance of agricultural crops are noted
The article reviews the results of studies of adaptive properties of the hybrid corn of different groups of maturity at the background of anthropogenic factors. It discusses the practical application of research results in order to maximize grain yields from 1 ha, environmentally friendly products (including at cultivation of corn on the protected areas), economically viable crop with maximum return on investment, as well as the possibility of extensive corn cultivation technology with limited material resources-money producers
ECONOMICAL AND BIOENERGETICAL EFFICIENCY OF WINTER BARLEY SORTS ON VARIOUS IRATION MINERAL NUTRITION
The results of the economical and bioenergetics effi-ciency estimation of using fertilizers of various winter barley sorts in the conditions of the South part of Ros-tov region are given and optimal variants of their usage are determined
The results of sunflower cultivation comparative analysis in the traditional system and direct seeding are given in the article
The article presents the results of three-year researches on the study of indexes of ripening of grafts-coefficient and conditional coefficient of ripening at 9 resistant table and technical varieties of grapes and indexes of their root-formation ability when rooting in water. There was cited the analysis of presence, direction and degree of correlative connections between two studied indexes
The article presents experimental data indicating that for the optimization of biological and food processing meat value at risk of aflatoxicosis in feeding chicken-broilers with barley-wheat and sunflower type one should include hullless barley grain at exposure of ozone of 3.0 hour complex with Bifidumbacterinum probiotics
