摘要: To evaluate the effects of selenium (Se) and vitamin E (Vit E) on female sika deer. This study was conducted using a 3 x 2 + 1 factorial experiment. Depending on treatment design, the deer were fed with the basal diet supplemented with 0.2, 0.3, and 0.4 mg of selenium as well as 100 and 200 IU of vitamin E per kg of dry matter (DM). Accordingly, six groups named G1 to G6 are involved in this study. In addition, group G0 was available in the study, in which the deer were fed with only basal diet. The results show that the final body weight (BW), average daily gain (ADG), and apparent digestibility of crude protein, ether extract, and neutral detergent fiber of the deer in G1 to G6 increased as the selenium level increased from 0.2 to 0.3 mg per kg of DM (P < 0.05). Higher IgG content of the deer was observed with the intake of selenium and vitamin E (P < 0.05). The total content of protein of the deer in G3 was higher than that in G0 (P < 0.05), and the activity of glutathione peroxidase increased following the increase in the supplementation levels of selenium and vitamin E (P < 0.05). Furthermore, selenium had significant effects on the concentration of T4 and T3 (P < 0.05). The optimum levels of selenium and vitamin E for 1-year-old female sika deer were 0.3 mg and 100 IU per kg of dietary DM, respectively.
