Oat grain has a great national economic significance. Firstly, it is a concentrated feed for farm animals. Secondly, it is the raw material for food production, most of all, for baby diet. In this regard, when used for feed purpose or for food production, it is necessary to knowledge the chemical composition of the oat grain. Our results demonstrated that by the content of chemical elements, among 70 species the differences were in membranous and hull-less oats. The grain of membranous oat of Ulov variety contained more silicon, potassium and calcium, comparing with the content of hull-less oat grains of Vyatkskiy variety. In a relatively favorable weather conditions of 2010 year, the Ulov oat grains contained more boron, sodium, aluminum, potassium, calcium. Vyatskiy hull-less oat grains at relatively favorable weather conditions of 2011 year, have a higher content of magnesium, phosphorus, calcium, manganese and zinc. Chemical composition of Ulov and Vyatskiy oat grain according to the 70 element have differs and depends on the meteorological conditions of the vegetation period. The membranous and hull-less oat grains did not contain heavy metals above the permissible values, regulated by Sanitary rules and norms 2.3.2.1078-01.

The studies, conducted in 2012-2013, showed that pre-sowing seed treatment by fungicides, biological products and micro fertilizers had a positive impact on the formation of grain yield of Ulov and Gunter varieties of oats. The experiments were carried out on cespitose-medium-podzolic, medium-loamy soil. During the research meteorological conditions evolved differently. As for temperature and moisture conditions for oat growth and development, 2012 year was more favorable. The vegetation period of 2013 was characterized by a relatively hot and dry weather. Seed pre-treatment of Ulov oat variety by zinc sulfate provided yield of 2.12 tons per hectare, which was 0.50 tons per hectare or 31% higher, than the yield in the embodiment, where the seeds were not treated. Grain yield of Gunter oats variety at preplant seed treatment with a mixture of micronutrients was significantly increased by 0.42 tons per hectare or 22%, compared to the yield in the control variant (without treatment). It is found, that the yield of Ulov oats variety has a panicle the number of grains positive strong correlation (r = 0,78). Yield of Gunter oats variety has a total number of plants to harvest a positive correlation (r = 0,61).

The effect of pre-sowing treatment and standards of their seeding rates on the productivity of oats of Yakov breed was established on the basis of results of two years of research on the sod-medium medium-loamy soils of the Middle Urals. The efficacy of pre-sowing seeds treatment with drugs Lamador, Planriz, Vial TrasT, ZhUSS was proved by increasing the productivity to 0.14-0.30 tons per hectare. The optimal seeding rate for oats of Yakov breed is 5 million pieces of seeds per hectare in the Middle Urals. We revealed the direct close correlation of Yakov oats productivity with inflorescence productivity (r = 0.84), with the weight of 1000 grains (r = 0.82), with plant height (r = 0.81) and with the kind of grain (r = 0.80).

The purpose of research is improving physiological and biochemical status and productive qualities of broiler chickens by including basic diet lactoamilovorin and potassium iodide. For experimental studies experimental and control groups formed randomly on the 35 day-old chicks, which were grown in Techa-of 42 days at the cellular content. It was found that the number of red blood cells in the blood of studied groups broiler chickens in the whole investigated period increased. leukocyte concentration was lower in broilers of the experimental group by 2.6%, compared to the control. The hemoglobin content increased in those chenie the entire period of study in a group of birds fed the probiotic and potassium iodide. Statistically significant differences in hematological parameters relative to those of the control group of birds observed in the integrated use of iodine preparations and probiotics in the period from 14 th to 42 th day. At 14, 21, 35 and 42 day old chicks advantage over the control treatment groups on the hemoglobin content amounted to 14.03, respectively; 10.40; 9.79 and 12.28%.Analyzing the morphological indicators of blood of experimental groups, it should be noted that they were within the physiological norm. The maximum effect is the physiological norm was observed in broiler chickens III experimental group, which in addition to the basic diet fed potassium iodide and lactoamilovorin.
