In order to reduce the impact of stress factors on the body of pigs, new technologies and efficient veterinary and preventive measures in breeding and cultivation are being developed. The results of our scientific and economic experiments found that the use in daily diets of pregnant and lactating sows according to our schemes of biological additives (to finish / day.): Laktobifid (1 g), Immunobak (1 g), Provagen (10 g ) Vetom 1.1 (50 mg / kg body weight), Bacell (0.3% by weight of the feed) and Monosporin (10 mL), contributes to the improvement of their reproductive qualities: for twins - on 2,2-12,2% by krupnoplodnosti - by 8,0-10,7%, for milk - by 8,9- 36,5%, at the preservation of pigs - by 1,3-8,3%, by weight of the nest 2 months of age - 22 , 9-38,9% compared with the control. At weaning piglets from sows experimental groups indicators of natural resistance were significantly higher. The best reproductive performance were observed in sows treated with diet and probiotic supplements Immunobak Bacell combined with Monosporin . The results of these experiments revealed adaptogenic properties of the studied additives, their ability to mitigate the impacts of technological stresses, reducing as a result of the cost of the products. Of great practical importance is the ability to predict the effectiveness of the use of additives which have antistress effect, depending on the body weight of animals, their age, frequency and duration of their application before and after the impact of technological stressors in the suckling period, the periods of rearing and fattening up of live weight and 100 и 120 kg

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
