ABSTRACT
The present study aimed to investigate the effects of dietary vitamin E (VE) supplementation on the growth performance, immune function, serum biochemical parameters, and antioxidant capacity of growing swan geese (Anser cygnoid). 240 four-week-old healthy swan geese were randomly divided into five groups (n = 48 each). Each group was subdivided into six replicates, with eight geese per replicate. Geese received basal diets, supplemented with either 0 (control), 10, 20, 40, or 80 IU/kg VE. All geese were treated for 12 weeks. The results showed that VE supplementation had no significant effect on body weight, but significantly decreased the average daily feed intake and the feed/gain ratio. Moreover, compared with control, the thymus index, serum SOD and GSH-Px increased significantly, while MDA decreased significantly in the 20, 40, and 80 IU/kg groups. In conclusion, dietary VE supplementation can increase the feed conversion ratio, thymus index, antioxidant defense function, and decrease oxidative damage of growing swan geese.
