Abstract

The objective of this study was to evaluate the effects of alfalfa meal and alfalfa saponin on growth performance and antioxidant function of finishing pigs. According to the similar species, age and parity, sixty finishing pigs with an initial body weight of (60.00±2.32) kg were randomly divided into 5 groups with 3 replicates in each group in a single-factor completely randomized block design. The experimental diets were supplemented with 0 (control group), 7.0% (experimental group Ⅰ), 14.0% (experimental group Ⅱ) and 21.0% (experimental group Ⅲ) alfalfa meal and 0.3% alfalfa saponin (experimental group Ⅳ), respectively. The pre-experiment lasted for 10 d, and the experiment lasted for 37 d. The results showed as follows: 1)the average daily feed intake and feed/gain in experimental groups Ⅰ, Ⅱ and Ⅲ were decreased as the alfalfa meal levels increasing and lower than those in control group (P>0.05). The average daily gain and average daily feed intake in experimental group Ⅳ were higher than those in control group (P>0.05), however, the feed/gain was lower than that in control group (P>0.05). 2) Adding alfalfa meal and alfalfa saponin improved the activities of superoxide dismutase (SOD) and glutathione peroxidase in liver and the SOD activity in eye muscle. The three indexes in experimental groups Ⅱ, Ⅲ and Ⅳ were significantly higher than those in control group (P<0.05 or P<0.01). In conclusion, the growth performance and antioxidant function of finishing pigs are improved by adding alfalfa meal or 0.3% alfalfa saponin in the diets.

Key words： alfalfa meal; alfalfa saponin; finishing pigs; growth performance; antioxidant function
