Effects of Corn DDGS Diets Supplemented with Conjugated Linoleic Acid or Betaine on Growth Performance, Serum Biochemical Indices and Antioxidant Function of Finishing Pigs
摘要
Abstract
This experiment was conducted to study the effects of corn distillers dried grains with solubles (DDGS) diets supplemented with conjugated linoleic acid (CLA) or betaine (BET) on growth performance, serum biochemical indices and antioxidant function of finishing pigs. Thirty-two crossed-bred pigs (Duroc x Landrace x Yorkshine) with an average body weight of (60 ±2) kg were randomly allotted into 4 treatments with 8 replicates per treatment and 1 pig per replicate. Pigs in group I (control group) were fed a corn-soybean basal diet, group H diet was used 30% corn DDGS to replace soybean and corn, and groups El, IV were fed the corn DDGS diets supplemented with 1 % CLA or 0.1 % BET, respectively. The trial lasted for 42 days. The results showed as follows: 1) there was no significant difference in growth performance among all groups (P>0.05). 2) Serum biochemical indices: compared with group I , the total protein (TP) content and alanine aminotransferase ( ALT) activity of group II were decreased significantly (P< 0.05) , and cholesterol (CHO) content of group IV was decreased significantly (P< 0.05). Compared with group II , glucose (GLU) content of group IV was increased significantly (P<0.05). 3) Serum antioxidant indices-, compared with group I , malondialdehyde (MDA) content of group H was increased significantly (P < 0. 05). Compared with group H , MDA content of group HI was decreased significantly (P < 0. 05) , and the activities of total superoxide dismutase (T-SOD) , glutathione peroxidase (GSH-Px) of groups HI , IV and total antioxidant capacity (T-AOC) of group H were increased significantly (P< 0.05). 4) Muscle antioxidant indices: compared with group I , MDA content of group II was increased significantly (P<0.05) . Compared with group II , MDA content of groups HI, IV was decreased significantly and T-AOC content was increased significantly (P<0.05). It is concluded that diets supplemented with 30% corn DDGS has no significant effects on growth performance of finishing pigs, while the antioxidant capability is decreased. Supplemented with 1% CLA or 0.1% BET in the corn DDGS diet can improve antioxidant capability to a certain extent. [ Chinese Journal of Animal Nutrition, 2012, 24(9) : 1737-1744]关键词
