In the article we have studied the exterior of golshtinizaited animals. The increase in number of measurements for specific dairy type and increase of productivity has been established
In the article we have presented the results of cultivation of apple-tree gardens with the application of Buton and Mival-agro growth regulators and their efficiency on grades of all terms of maturing. Positive action of preparations on grades of all terms of maturing has been noted
The article gives an overview of the current
developments of scientists of the Russian Federation in
the field of production of feed concentrates and
premixes for cattle. A critical analysis of feed
concentrates and premixes of preventive and
compensatory action for the control of mycotoxicoses
was carried out, and their brief characteristics were
given. The characteristic of biologically active
substances and fillers, declared in the recipes of feed
concentrates and premixes, is given. It is shown that
the alternative to existing feed concentrates and
premixes on the market is vitamin-mineral fodder
concentrate "Tetra +", developed by the authors. Based
on the analysis, a conclusion was made about the
relevance of studies to identify the effectiveness of
vitamin-mineral fodder concentrate "Tetra +" in
livestock
The article presents the results of studying the peculiarities of growth and fruiting of trees of sweet cherry with varying density. It is established that the average yield for the years of fruiting does not depend on tree planting schemes, and higher profitability of production is marked with the scheme of 5,0×3,0 5,0×2,5 m
The article contains the review of the basic standards providing ecologically safe recycling of a manure at modern pig-breeding complexes with a Capacity of 12 000 and 50 000 heads of a finishers a year. The capacity of storehouses for liquid fraction is defined
This article shows the results of the studies of the influence of fertilizers on plant height and accumulation of biomass in alfalfa plants
In this article, an anthropogenic influence on natural
ecosystem such as an excavation of sand is discussed.
Investigations were done in Kuyar Forest District of
the Mari El Republic on a sandpit. The adjacent plot
of natural forest was taken as a control. For evaluation
the degree of environment transformation as a result of
sand excavation several indicators were used. As
indicators of physical soil degradation - thickness of
organogenic horizon and soil density; for assessment a
chemical degradation – content of main nutrients and
humus; as an indicator of biological degradation – the
level of active microbial biomass. Besides, a potential
phytotoxicity was estimated. The study proved:
physical and chemical parameters corresponded with
the fourth degree of soil degradation, at the same time,
biological parameters approximated to parameters of
soil from natural territory
Farms of Krasnodar region purchase cattle of milk, combined and meat direction of productivity. Imported cattle are accompanied with documents which differ from analogous ones specified in such cases by pedigree service of Russia. There were studied 1000 heads of symmental cattle of milk-meat direction of productivity imported from Austria. More than 5000 kg of milk can be obtained from cattle of symmental breed of milk-meat direction of productivity, except it they show enough high meat productivity. The analysis of accompanying documents on purchased cattle is joined not only with language barrier but with the lack of knowledge of adopted abbreviations, contractions and other attributes used by foreign breeders abroad. Having studied the accompanying documents connected with hereditary information of purchased cattle there was determined that imported heifers and their mothers were obtained in Austria, and mothers of bulls on 55,5% obtained in Austria and 41,6% in Germany. So, on formation of imported micropopulation of cattle greatly influenced the breeding school of Germany. In accordance with the adopted classification in Austria due to revealed cases of adoption of Holstein blood, there is a ground to consider the present herd as a belonging to the group of pure breed of symmental cattle and in prospect to conduct the mating of cattle with pure breed symmental oxen with the aim of absorption of mixtures of Holstein blood in pedigree. The researches determined that one can purchase the producers with characteristics of milk productivity at daughters of oxen not lower than Austrian indexes on voluminous milking and German – on milk quality, the purchase of symmental cattle from other countries must be subjected to this demand.
The algorithms of estimating breeding value, allowing increasing its accuracy several times are developed on the basis of establishment of the selection characteristics of existing selection criteria and the definition of the coefficient
