INFLUENCE OF BIOLOGICAL ADDITIVES ON RESISTANCE, METABOLISM AND EFFICIENCY OF PIGS
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 anti-stress 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
