Abstract

This experiment was conducted to investigate the effects of dietary alfalfa meal on slaughter performance, carcass quality, muscle fatty acid and amino acid contents of Sushan pigs, so as to determine the feasibility of using alfalfa meal as crude fiber to improve carcass quality of Sushan pigs. A total of 60 healthy pigs with (60.0±2.0) kg body weight, were randomly divided into 4 groups with 3 replicates in each group and 5 pigs in each replicate. The control group was fed a basic diet. The experimental groups were fed the basic diet supplemented with 10%, 15% and 20% alfalfa meal, respectively. The pre-experiment lasted for 7 days and the experiment lasted for 80 days. The results showed as follows:1) with the increase of dietary alfalfa meal supplemental level, the slaughter rate, oil weight and back-fat thickness in experiment groups Ⅰ, Ⅱ and Ⅲ were higher than those in control group, and the lean meat rate was lower than that in control group. The differences of oil weight and back-fat thickness between experiment groups and control group were extremely significant (P<0.01). 2) Addition of alfalfa meal to diet had a significant effect on muscle color and dehydration rate of Sushan pigs. The brightness value of longissimus dorsi muscle in experiment groups Ⅰ, Ⅱ and Ⅲ was significantly higher than that in control group (P<0.05), redness value and yellowness value were significantly lower than those in control group (P<0.01). Water loss rate of longissimus dorsi muscle in experiment groups Ⅰ, Ⅱ and Ⅲ was lower than that in control group, and there was a significant difference between experiment group Ⅱ and control group (P<0.05). 3) Addition of alfalfa meal to diets affected the composition of fatty acid and amino acid in muscle of Sushan pigs. The contents of total monounsaturated fatty acids, essential amino acids and flavor amino acid in experiment groups Ⅰ, Ⅱ and Ⅲ were higher than those in control group. Essential amino acid and flavor amino acid contents in experiment group Ⅰ were significantly different from those in control group (P<0.01). In conclusion, addition of 10% alfalfa meal can significantly improve muscle color, muscle tenderness and taste, and then improve the pork quality of Sushan pigs.
