Description
The article provides a convincing argument for the preference of wool and fur products over artificial and synthetic textile fibers. It is noted that artificial fibers and synthetics have negative ionization, while natural wool has positive ionization. It is emphasized that negative ionization is far from harmless to humans. The analysis of the state of sheep breeding in the Russian Federation is given and this industry in the Rostov region is characterized against this background. The data on the number and productivity of sheep of the main age and sex groups, the production of young animals per one hundred ewes are presented. The characteristic of tribal resources of the country and region is given. The breeding base of the industry in the Russian Federation is represented by 205 breeding organizations, including 3 breeding and genetic centers, 44 breeding plants, 145 breeding reproducers and 13 gene pool farms, which contain 1389.8 thousand sheep (39.0 % of their total number in agricultural organizations and 6.6 % of the sheep population in farms of all categories), including 904.7 thousand Queens (35.0 and 6.2%, respectively). The breeding base of the Rostov region has eleven farms, of which 6 breeding plants for such breeds as the Soviet Merino and salskaya and 5 breeding reproducers. In addition to these breed resources, there are breeding reproducers for the qigai and edilbaev breeds in the region. Total number of breeding sheep in the region is almost 44 thousand. The article indicates main problems in the development of the industry and ways and means to solve them

Description
An important factor in improving the efficiency of production in the agro-industrial sector is to improve the quality of poultry products and their processing. The article presents the dynamics of the influence of stimulating drugs on the productive qualities of the black African ostrich. The reserves of increasing the production of eggs of black African ostriches and its quality due to the use of stimulating drugs were revealed. The effect of the use of the drug called "Radostin Vitasil" on the chemical composition of eggs, egg production of black African ostriches is shown. The obtained research results convincingly prove that the mass of ostrich eggs of the experimental groups significantly exceeded the control by 5.45 and 3.11%, respectively. Changes in the mass of white and yolk of the egg of ostriches of experimental groups as a result of feeding the drug "Radostin Vitasil" affected the ratio of white/yolk, which slightly decreased towards the optimal. There was a significant difference in the content of carotenoids and vitamin A in the egg yolk of the I experimental group by 10.98% and 10.05%, in the II experimental group-9.15% and 6.35%, in comparison with similar indicators in the control group, respectively. There was an excess of vitamin E level in the eggs of the experimental groups in relation to the control by 6.73 and 3.42%. The results of incubation showed that the stimulating drug "Radostin Vitasil" had a positive effect on the process of embryonic development. The calculated economic efficiency of the drug "Radostin Vitasil" confirmed the feasibility of using this drug in the production of black African ostriches eggs

EXCHANGE PROCESSES IN THE BODY OF BROILER CHICKENS WHEN USING THE FEED ADDITIVE INNOVIT E 60
Description
Vitamin E, having an antioxidant effect, also has a versatile effect on metabolism. It is proved that vitamin E is necessary for the integrity and optimal function of the reproductive, muscle, circulatory, nervous and immune systems. The feed additive Innovit E 60 was produced in the Russian Federation by the MEGAMIX company using innovative technology, which has no analogues in the world. The article presents the test results of the Innovit E 60 feed additive as a part of premixes for the purpose of enriching compound feeds for broiler chickens with vitamin E. The authors have found that the studied feed additive activated metabolic processes in the body of broiler chickens of ROSS 308 cross. Chickens of the experimental group better digested nutrients feed in comparison with analogues of the control group. A significant increase in the digestibility of crude protein by chickens of the experimental groups was found to be 1.11 and 0.92%, crude fat - by 2.11 and 1.85%, BEV - by 2.53 and 2.24%. The deposition of nitrogen in the body of the chickens of the experimental groups is higher than in the control group by 5.73 and 5.05%, and its use from the accepted - by 2.94 and 2.56%. By the end of the feeding, the difference in live weight was 90.3 (4.25%) and 68.5 g (3.22%), and feed costs per 1 kg of live weight gain decreased by 0.06 and 0.04 kg. The control slaughter of broiler chickens showed that the slaughter yield in the experimental groups increased: males by 0.6 and 0.4%, chickens by 0.8 and 0.5%; the mass of pectoral muscles of males - by 46.0 and 41.0g, chickens - by 43.0 and 36.0g. The feed additive Innovit E 60 in the diets of broiler chickens helps to improve the digestibility of the main nutrients of the feed, increase live weight, slaughter exit and exit of the pectoral muscles
