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 supple mentation 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.
