The results of small (20-22 cm) and relatively deep main processing of the soil (27-30 cm) and variable rate application depth of arable horizon of doses of mineral nutrition (N and P2O5) on yield of spring barley. It is established that ploughing soil up to 30 cm (pillars of Cibima) with in-corporation at the same depth easy phosphorus-rhenium increases the biological activity of the soil microflora involved in the proposal of cellulose substrates is a means of increasing the fertility of light chestnut soil, which is especially important for rainfed conditions. The average crop capacity in the shallow plowing is 2 t/ha and was lower at 15% compared to Varian, where he held a deep subsurface tillage. By years of research sum-total biological activity in the deep subsurface treat-ment amounted to 930 mg of amino acids per gram of leaf, which is higher by 26% the variant with shallow plowing. Compared to shallow ploughing (option 1) at subsurface relatively deep processing of crude soil (option 2) there is greater accumulation of productive moisture in a meter layer. In the period of tillering of plants at average moisture reserves in option 2 is higher by 16% than in option 1 and constitute a 147 mm. In phase trubavina-earing and full maturity of the spring-barley the difference between the productive moisture content increases to between 20 and 33% in the direction of no-till deep processing. Relatively high soil moisture (a consequence of the method of tillage) contributed to a more rapid transition of phosphates in the horizon of 25-30 cm and nitrate in the layer 10-15 cm in available forms of nutrients for soil microorganisms. It is revealed that the application rate of nitrogen and phosphorus should be linked with the main processing of the soil, and the peculiarities of development of the root system of cultivated crops.

The authors of this article conducted a study of the population structure of Convallaria majalis L. and Polygonatum multiflorum (L.) All. flowered relating to protected species and included in the Red book of Moscow and Moscow region. For the first time in the Bitsa forest Park based on the characteristics of stages of ontomorphogenesis of the investigated species described and analyzed the age structure of their populations.

The article presents a methodology which includes a set of analytical and applied research - analysis in the field of standardization of documents, technical documentation industry, scientific and technical literature on the profile of studies, documents of patent licensing division, information technical regulatory framework, as well as Russian legislation, the Customs Union and the EU in terms of organic farming and organic products. According to the analysis conducted ranking of existing requirements to organic products of animal origin and methods of production, scientifically proven to build documents in the system of the organic animal products. The methodology involves a number of techniques, as a result of which the system will be designed instruments of technical regulation of organic products of animal origin. The results of the work and the proposed methodology as a whole can be the basis for the legislative framework in the field of organic production in all sectors of the food industry, to protect the rights of consumers, including protection against tampering of organic products on the market.

Studied chemical composition and amino-acid content of meat in broiler muscle tissue, mostly treated diet feed additive “Mikofiks” in comparison with the meat of broilers not receiving supplement. Define the comparative evaluation of the biological activity of the experimental and control of meat chickens, protein amino-acid score of pectoral muscles of broilers of cross-country “Siberian”. It was found that the use of the feed additive “Mikofiks” increases the physiological activity of chickens and weight gain. The chemical composition and calorific value of broiler meat treated with the additive does have some differences from the meat of chickens that received feed without additives “Mikofiks”. The moisture of meat of experimental chickens was an increase in 1.68%, and the energy value in 10,3-10,7%. In the white meat broiler of experimental group content of essential amino-acids in total increased by 2.7%, nonessential amino acids content decreased by 0.79%. The ratio of the amount of essential amino acids indispensable to the white meat of chickens of experimental group was 2.89% lower than in the control of broiler meat. However, the ratio of tryptophan to hydroxyproline increased by 23,6%. In the protein broiler of experimental group took place a limiting amino-acid (score) - tryptophan. Based on the conclusions of the data that the feed additive “Mikofiks” fattening broiler increases weight gain, and positive changes in the chemical composition of the meat defined by increased content of some essential amino acids, with the score (the limiting amino acid) - tryptophan.

In this work the study of the structure and features of development in the ontogeny of the bone marrow of Guinea fowls of the Volga white breed. Bone marrow is located in the cells of the spongy substance, and with age, its absolute mass increases, and the relative mass is reduced. In the period from 1 to 60 days age was observed the highest content of bone marrow in the skeleton of a Guinea fowl. In males the number of bone marrow more than females, in average by 1.5-2%. The bulk of the marrow from the Guinea fowls at the age from 1 to 90 days are in the peripheral skeleton, more than 55% in the pelvic limbs. The axial skeleton of the Guinea fowl at this age contains about one third of all bone marrow and much of it is concentrated in the spinal column. With age, the saturation of the axial skeleton bone marrow sharply increases and reaches to 48.1% of the total content in the skeleton of a Guinea fowl. The peak saturation of the skeleton by bone marrow observed in the first two months of life Guinea fowls. Then this figure was relatively stable until the age of 90 days varies slightly. With 180 day age, there is a sharp drop of saturation of the skeleton of a Guinea fowl bone marrow. At one year of age, the figure is only 57-59% of the saturation of the skeleton by bone marrow at the age of 90 days. With age, red marrow is replaced by yellow bone marrow. Microscopy of smears of bone marrow of individual fat cells found in red bone marrow in the daily age. At the age of 60 days there is a replacement of red bone marrow yellow 20-28%, and in 90 days in 40%. At the age of 365 days, almost the entire bone marrow is represented by yellow.
