- Abstract
The experiment was to investigate the effect of selenium oligosaccharide alleviating zealenone (ZEA) on growth performance, plasma biochemical indexes, antioxidant function and intestinal microflora of piglets. A total of 60 piglets weaned at 35 d of age were randomly divided into four groups. The piglets in group C were fed with a basal diet, piglets in group Z were fed with a basal diet + 2 mg/kg ZEA, piglets in group Z+Se1 were fed with a basal diet + 2 mg/kg ZEA+ 0.3 mg/kg selenium oligosaccharide, and piglets in group Z+Se2 were fed with a basal diet + 2 mg/kg ZEA+ 0.5 mg/kg selenium oligosaccharide. The pre-experiment lasted for 7 d, and the experiment lasted for 42 d. The results showed that the feed to gain ratio of piglets in group Z+Se1 and group Z+Se2 was extremely lower than that in group Z (P<0.01). Compared with group C, the activity of ALT and AST of piglets in plasma in group Z was extremely increased (P<0.01). The content of CHO and TG in group Z+Se2 were extremely decreased (P<0.01). Compared with group Z, the activity of ALT, AST, the content of TG and CHO of piglets in group Z+Se2 was extremely or significantly decreased (P<0.01 or P<0.05). Compared with group C, the CAT, GSH-Px, T-SOD activity and T-AOC of piglets in group Z were extremely or significantly decreased (P<0.01 or P<0.05), and MDA content was extremely increased (P<0.01). Compared with group Z, the activity of T-SOD and GSH-Px in group Z+Se1 was extremely or significantly increased (P<0.01 or P<0.05), and the content of MDA was extremely decreased (P<0.01). The activity of T-SOD, CAT, GSH-Px and T-AOC of piglets in group Z+Se2 were extremely increased (P<0.01), while the content of MDA was extremely decreased (P<0.01). Compared with group C, the number of Salmonella in intestinal tract of piglets in group Z was extremely increased (P<0.01), and the number of Lactobacillus and Bifidobacterium was extremely decreased (P<0.01). Compared with group Z, the number of Salmonella in intestinal tract of piglets in group Z+Se1 was extremely decreased (P<0.01), and the number of Bifidobacteria was significantly increased (P<0.05). The number of Salmonella in intestinal tract of piglets in group Z+Se2 was extremely decreased (P<0.01), and the number of Lactobacillus and Bifidobacteria was extremely increased (P<0.01). The experiment indicates that oligosaccharide selenium can alleviate the ZEA-induced decline growth performance and antioxidant function of piglets, reduce ZEA-induced increase plasma ALT and AST activity, and alleviates the imbalance of intestinal flora caused by ZEA.
