- Abstract
The purpose of this study was to evaluate the effects of different supplemental levels of betaine on growth characteristics, biochemical indices and antioxidant function in serum of small tail Han sheep in summer. Thirty- six small tail Han sheep lambs (three months old) were randomly divided into four groups with nine sheep in each group. Sheep in control group, group one, two and three were provided with 0, 2, 4 and 6 g betaine every day respectively. The pre-trial period was 7 days and the formal trial period was 42 days. Growth performance, serum biochemical indexes and antioxidant function were mea⁃ sured in this experiment. The results showed as follows: ① compared with the control group, the average daily gain (ADG) of group two was significantly increased (P<0.05) and the feed to gain ratio (F/G) was significantly decreased (P<0.05). ② Compared with the control group, the serum urea nitrogen (BUN) of group one was significantly increased (P<0.05). Serum total cholesterol (TC) and albumin (ALB) of group two significantly increased (P<0.05). Serum triacylglycerol (TG) of group three was significantly decreased (P<0.05) and its lactate dehydro⁃ genase (LDH) was increased significantly(P<0.05). Serum magnesium (Mg) of groups one, two and three was significantly increased (P<0.05). Beta⁃ ine had no significant effect on serum biochemical indices such as serum protein (P>0.05). ③ Compared with the control group, serum total antioxidant capacity (T-AOC) of group one and group two were significantly increased (P<0.05), and serum malondi⁃ aldehyde (MDA) content of groups one, two and three was significantly decreased (P<0.05). This showed that the addition of 2 g/d betaine in the diet ration improved the growth performance, regulated fat metab⁃ olism and improved serum antioxidant capacity of small tail Han sheep in summer.
