Parameters biochemical studies of blood and sperm of boars in conditions of adaptation

Abstract

Correlation between the activity of succinate dehydrogenase and cytochrom oxidase was determined. If the activity of succinate dehydrogenase was highest in Yorkshire boars, then cytochrom oxidase activity in these animals was the most active as well. Age dynamics in the direction of increasing of macro-blood elements content in blood of animals was determined, indicating the increased metabolism in the body. In the study of humoral factors of body defense it was determined that the level of both lysozyme and bactericidal and betalysine activity of blood serum of animals differed not significantly with age. Fertilization rate of sows of Landrace breed was higher by 3.3% compared to their coevals of Yorkshire breed. Thus the Yorkshire breed of pigs were easily adapted to management conditions.
