Abstract

The effectiveness of using 20-hydroxyecdysone in the diet of piglets during the growing period and its effect on the formation of natural resistance, the antioxidant defense system of the body and their meat productivity were studied. The introduction of 20-hydroxyecdysone into the diet at the rate of 30 mg per kg of feed positively influenced on the bactericidal and lysozyme activity of blood serum, which in the experimental group were higher by 12,9 and 14,0%, respectively, compared with the control. The activity of superoxide dismutase and catalase enzymes in blood plasma in piglets of the experimental group was statistically significantly higher compared to the control. On the contrary, the content of malondialdehyde in blood plasma was statistically significantly lower in piglets of the experimental group compared with the control (17,1%, P≤0,01). In piglets of the experimental group, in comparison with the control, the output of muscle tissue (by 5,3%, P≤0,01), the area of the “muscle eye” (34,5%, P≤0,05) was statistically significantly higher, with less adipose tissue outlet.
