BIOLOGICAL PROPERTIES OF BLACK LEACHED SOILS OF THE ROSTOV REGION
06.00.00 Agricultural sciences
DescriptionThe regularity that increases biological and enzymatic activity with increasing the age of the deposits of 10 to 82 years has been shown. The indicator of recovery of black leached soil steppes can be presented as invert-ase activity and humus content, as well as reducing the density of the soil. Integrated indicator of the biological properties decreases with decreasing age deposits: 82 years (100%) - 26 years (84%) - 16 and 10 years (74%) - arable land (64%)

BIOLOGICAL FEATURES AND PRODUCTIVITY OF BLACK-AND-WHITE CATTLE
06.00.00 Agricultural sciences
DescriptionThe behavior, interior and milk yield of the mature Black-and-White cows with various productivity levels, as well as etology of the replacement heifers are researched. The superiority of the high milk yielding cows for the lying duration and eating feed and water is revealed. Reduced variability of vital behavioral actions of animals is found. In addition, high yielding cows has been lower variability in all feeding acts. It was noted that high yielding animals exceeded equal age cows by the level of most interior factors. The differences were significant on the content of hemoglobin, vitamin E, and especially on the content of iron. Positive correlations between some interior design indicators is found. The analysis of lifetime productivity during our research found that high milk yielding cows had highest yields on the first lactation and kept the same level in the next lactations with insignificant variations. The lower productivity animals reached maximal yields on the third lactation with the followed downward trend. Differences between groups in lifetime productivity during research amounted to 16 992 kg. The significant superiority of the heifers with high grown intensity above equal age animals for the duration of feed and water eating, physiological functions and lying. The analysis of variation coefficient is confirmed the observed regularities.

BIOLOGICAL EFFICIENCY OF FUNGICIDES IN WINTER WHEAT CROPS AND THEIR INFLUENCE ON CROP YIELD
06.00.00 Agricultural sciences
DescriptionFor the production of high quality winter wheat grain, it is necessary to observe the technology of growing the crop and creating optimal conditions for the growth and development of plants. An important role in it is played not only by agrotechnical measures, but also by effective protection of crops from pests. The phytosanitary state of winter wheat sowings has worsened significantly in recent years, however, the degree of damage to crops and the harmfulness of fungal diseases can be significantly reduced, and in some cases completely prevented by treatment of crops with fungicides. The range of fungicides is improved annually by incorporating more effective and less environmentally hazardous preparations. The research is aimed at determining the optimal rates of consumption, the biological effectiveness of new fungicides and assessing their effect on the yield of winter wheat. As a result, it has been established that treatment with Abucus Ultra with a rate of 1.0 l / ha has protective properties, but does not treat plants (72.2%). This further leads to a loss of an average of about 0.5 tons of grain per hectare. Fungicide Akanto Plus in the investigated rates of consumption has good protective and eradicating (healing) properties and with a decrease in the rate of consumption of less loss of yield. Thus, the choice of the preparation and its consumption rate should be based on an understanding of the phytosanitary situation, taking into account the condition of crops and the agroclimatic situation

BIOLOGICAL ASSESSMENT OF ENVIRONMENTALLY SAFE HERBAL FEED ADDITIVES FOR QUAIL
06.00.00 Agricultural sciences
DescriptionThe work on the study of the biological assessment of environmentally safe herbal feed additives for quail has found in the supplement that contains the seeds of soybean varieties Valens, the bird had higher growth rates than in the supplement of soybean varieties Vila. Using as a protein-based supplement autoclaved soybean Valens varieties increases the profitability of meat quails from 22.52 to 28.76%, and the economic effect when used - to 32.5 rubles per 1000 quails compared with the addition made from soybean of Vilan varieties

BIOLOGICAL ACTIVITY OF DIFFERENT SORTS OF HUMIC COMPLEX AND ITS INFLUENCE ON THE GROWTH OF PLANTS
06.00.00 Agricultural sciences
DescriptionThe article represents the results of the experiments on biological activity of humits of different sorts. The object of research was humic preparation called Vermistar, which was obtained by vermiculturing, on the basis of brown coal. Humics are group of high-molecular substances which have high physiological activity. Humic substances stimulate all biochemical processes on all the stages of plant growth. They change the permeability of the cell membranes, increase activity of ferments, amount of chlorophyll and productivity of photosynthesis. Also humits are not toxic; they don’t have carcinogen and mutagenic effects, so we have a chance of getting environmentally friendly products. The experiment results show high biological activity of humic preparations. Usage of humic stimulates germination, the accumulation of vegetative mass, weight gain. The frequency of shoot has been increased by 17-32%. Height of shoots, roots and vegetative mass has also been increased

PROTEIN OF MEAT AND BONE MEAL FOR PIGS
06.00.00 Agricultural sciences
DescriptionThe modern requirements of intergovernmental standards to the quality and safety of livestock produce provide for the use of highly productive animals capable under small expenses to produce more the high quality produce. In particular, at the formation of meat productivity at pigs the great significance has an achievement of optimal digestion and assimilability of consumed fodder means. In the connection, the study of digestion of meat and bone meal from slaughterhouse wastes of cattle (MCM) and poultry (MCBM) presents the scientific interest. In the fodder experience on the growing pigs with the fistula of iliac intestines there was investigated the digestion of two types of meat and bone meal from slaughterhouse wastes of cattle (MCM) and poultry (MKBM). The iliac accessibility of amino acids of meat and bone meal found itself too low: 49,3 % - 69,3 %. The accessibility of general protein reliably did not differ from the average accessibility on main amino acids - 61,5 %. To count the real iliac accessibility of raw protein and amino acids of meat and bone meal there was determined an endogenous emission of these substances on the casein diet. The real iliac accessibility of protein and individual amino acids did not leave the limits in 73% on МCM and 69% - on МCBМ. The accessibility of lysine, leucine and isoleucine MCBM is reliably higher than the same in MCM (P
