ОЦІНКА ВПЛИВУ АНТИСТРЕСОВИХ ТА СТИМУЛЮЮЧИХ ПРЕПАРАТІВ НА ПОКАЗНИКИ ПРИРОДНОЇ РЕЗИСТЕНТНОСТІ СВИНЕЙ
Comparative estimation in use of anti-stress and bio-stimulating preparations on suckling piglets of various genotypes - White Breed and White Landrace Breed has been given. Influence of biological preparations: gamavit, katozal and tymogen on natural resistance and productive indices of swine at uniphase growing in comparative aspect have been determined. The state of natural swine resistance with various abiotic agents (temperature, humidity, group keeping of milking sows with piglets) on dynamic of live weight and growth intensity (average daily gain), morphological (erythrocytes, leukocytes), biochemical (total protein, albumins, α, β, γ-globulins), humoral (antibacterial and lysocim activity of blood serum) and cell indices of protection (phagocyte activity of neutrophils, phagocyte index) have been studied. Gamavit, as biological stimulator, increases BASK, LASK; it also influences as detoxicanting and stimulating action; it stimulates swine body weight increase, increases their stress resistance. Katozal shows stimulating action on metabolism, increases organism resistance in stress, leads to the growth and development of animals. Tymogen, as a biocorrector, consists of glutamic acid and tryptophan, induces the formation of protective functions in piglets with diarrheic syndrome, and preserves organism homeostasis and biochemical indices.
