The article discusses the role and particular importance to highly productive cows in the breeding of dairy cattle. Currently, one of the priorities of the agricultural sector is the creation of highly productive dairy herd, since it is by far a priority, and it is the country’s food security. We have studied the question of variability genotype bulls under the influence of the physiological state of the mothers, in particular the impact of the intensity and duration of maternal lactation dairy cows in the tribal days Quality sons. The physiological condition of cows is characterized by the level of activity of lactation, and reproductive functions, ie fertility, duration of service period and the number of milking days. As is known, there is a very close link between these functions. Cow fertility depends primarily on coherence of physiological functions. The beginning of all this is a normal metabolism in the body, which is of utmost importance for selection vysokomolochnyh cows. Metabolic disorders in the body vysokomolochnyh cows (ketosis), caused by an unbalanced feeding, shortage of certain nutrients and elements, as well as excessive razdaivaniem with a high proportion of concentrated feed leads to the breakdown of the body’s physiological functions, especially the reproductive organs. In this regard, we consider these factors creates unfavorable conditions for the normal maturation of the egg, the birth and fetal growth retardation. Therefore, when selecting herd replacements necessary to conduct a comprehensive assessment, including whether the physiological state of the mother during the birth of offspring.

In article results of researches on studying of influence of various doses of nanoproduct “M-Feed” on hematological parameters and the dynamics of live weight Kalmyk breed rams for ages. The authors found that in almost identical production live weight of the rams of the second experimental group, treated with M-Feed” dosage of 5 g per head per day by the end of the experience had a live weight at 6,26 kg more than control counterparts (P < 0.01), 4.1 kg, than the first experimental group (P < 0.001) and 2,84 kg in the third group (P < 0.01). During the period of experiment the rams in the second experimental group was given absolute increase 39,57 kg, which is higher than that of control - 6,06 kg, analogues of the first experimental group - 4,43 kg and the third - on 2,51 kg. In the blood of growing rams Kalmyk breed of sheep experimental groups treated with different dosages of feed additives “M-Feed” there has been some increase in the number of erythrocytes and hemoglobin. Thus, the content of erythrocytes in the blood of rams from the control group was 1.2% (P > 0.05) and 0.8% (P > 0.05) lower than that of counterparts, from the first experimental group, 12,14 and 10.8% (P < 0.01), from the second group by 3.2 and 2.7% than in the third experimental group (P > 0.05).

The article presents data and analysis of the dynamics of development of individual parts of the skeleton, half-carcasses of young Tsigal, South Ural and Stavropol breeds in the conditions of the Southern Urals. Comprehensive study of the growth and development of the skeleton in the postnatal ontogenesis will develop methods of purposeful influence on the formation of myasnosti animals by sex, age and breed. The experimental data suggest that infants rams have better development of the skeleton than Mutton, due to sexual dimorphism. Thus, the superiority of the rams Tsigal rock peers on the total weight of the bones at birth was 5 g (1.5%) by weight of the bones of the axial skeleton Division - 2.3 g (1.5%), peripheral - 2.7g (1.5%) in the rock Yuzhnouralskaya this difference in magnitude to the studied parameters rams were respectively 28 g (9.5%), 12.8 g (9.5%) and 15.2 g (9.5%) at Stavropol breed - 15 g (5.3%), 6.8 g (5.3%) and 8.2 g (5.3%). A similar pattern was observed in the subsequent age periods.

The article presents the results of a study of meat efficiency of young Kazakh fat-tailed breed grubosherstnoj. The object of the study were rams, valushki, Mutton studied breed. The obtained data and their analysis shows that intensive cultivation of rams, and valushkov yarochek improved the slaughter qualities, as evidenced by the increase in slaughter yield with age. Rams, and Mutton valushki Kazakh fat-tailed breed grubosherstnoj distinguished by high slaughter qualities. This determines its prospects of breeding for high biological value of meat - lamb.

The article shows the development of the main departments of the muscle tissue depending on the genotype, sex, age and physiological state. It is established that, as in certain age periods, and during cultivation, the highest growth rate, as muscle mass halves, and its divisions, was the difference barancik all genotypes, and the minimum of jarocki, valoski took an intermediate position.

The article presents the results of experimental studies in the PC gland domestic ducks. In particular on the impact of probiotic SBA on the development PC gland ducks in postnatal ontogenesis. The results showed that bacterial drug stimulates the growth and development of the glandular structures and muscle membrane, that is confirmed by reliable indicators on 57th day life ducks.

Data provided in the article was received when studying a ferriferous stomach of ducklings in incubatory (antenatal) and post-incubatory (post-natal) the periods of their life.

This article shows the results of multiyear studies of the process of biogenic migration, transformation, accumulation of antimony in the body of sheep in the Kadamjai primary and secondary antimony biogeochemical subprovince (Kyrgyzstan).

Monitoring: the process of biogenic migration, transformation, accumulation of antimony in the water, soils, plants in the Kadamjai primary and secondary antimony biogeochemical subprovince (Kyrgyzstan), is determined by the species composition of the soil microflora and adequately assessed their condition.

In work results of researches on studying influence low intensity a laser irradiation on the maintenance of amino acids in blood and are submitted to a seed of bulls of different breeds used in cooperative societies and farms of the Kirghiz Republic.

In given clause the condition, and ways of increase of a production efficiency of production of animal industries of the Kirghiz Republic as it is the important branch of an agriculture giving about half of his gross output is considered.
