【 摘 要 】

To evaluate the effects of gelatin and starch encapsulated vitamin A on growth performance, immune status and antioxidant capacity in weaned piglets, a total of 96 weaned piglets (body weight = 9.11 ± 0.03 kg, 30-d-old) were randomly allotted to 3 treatments with 4 replications of 8 piglets each. The 3 treatments were control diet (basal diet without addition of vitamin A), gelatin vitamin A diet (basal diet + 13,500 IU/kg gelatin encapsulated vitamin A), and starch vitamin A diet (basal diet + 13,500 IU/kg starch encapsulated vitamin A), respectively. The results showed that piglets fed starch vitamin A diet had significantly higher final body weight and average daily gain compared to those in control and gelatin vitamin A groups (P < 0.05). Gelatin and starch vitamin A supplementation both highly increased serum retinol concentration and immunoglobulin (Ig) M level when compared with the control group (P < 0.05). Additionally, serum IgA level and glutathione peroxidase (GSH-Px) activity were significantly increased by gelatin vitamin A diet on d 21 and starch vitamin A diet on d 42, respectively (P < 0.05). These results demonstrated that dietary supplementation of vitamin A could improve immune function and antioxidant capacity in weaned piglets, and starch vitamin A is better than gelatin vitamin A, especially in promoting the growth performance of piglets.
