Effect of selenium and vitamin E supplementation on the quantity and quality of the pork production and selenium accumulation in organism of fattening pigs.

摘要

Selenium accumulates in the organism of livestock and thus increases the additive value of meat, prolongs its storage time, and improves culinary properties. In addition, selenium in meat is an important source of selenium in human nutrition. The aim of present research was to determine the effects of supplementation of diet with antioxidant preparation containing Se and vitamin E (0.1 mg and 20 mg kg-1, respectively) on the growth of fattening pigs, to assess the selenium accumulation in their organism, and to evaluate its effects on the physical-chemical properties of the meat. Two groups (12 pigs in each) of analogous pigs' hybrid were investigated. Experimental group got the supplements of antioxidants. Addition of Se and vitamin E preparation to diet had no significant effect on feed intake, animal growth and meat quality indicators. Blood analyses showed the accumulation of trace element selenium in fattening pigs.
