The aim of the experiment was to study the effects of Astragalus compound Chinese herbal medicine on the serum immune indexes, meat quality, and muscle nutrients of finishing pigs. A total of 250 finishing pigs of 170 days of age with similar body condition and body weight were randomly divided into five groups with five replicates per group and 10 finishing pigs per replicate. The control group was fed a basal diet, and the experimental groups were fed diets supplemented with 0.6%, 0.8%, 1.0%, and 1.2% Astragalus compound Chinese herbal medicine (ACM), respectively. The experiment lasted for 60 days. The results showed that the contents of serum immunoglobulin and complement protein were significantly higher in the 0.8% ACM group and 1.0% ACM group than in the control group (P<0.05). Compared with the control group, the muscle water loss rate of the experimental groups decreased significantly (P<0.05), the redness value of meat color increased significantly (P<0.05), and the yellowness value decreased significantly (P<0.05). Compared with the control group, the water content in meat of the experimental groups decreased significantly (P<0.05), the content of crude fat in meat of the 1.0% ACM group increased significantly (P<0.05), and the content of crude protein in meat of the 0.8% ACM group and 1.2% ACM group increased significantly (P<0.05). Adding 1.2% ACM significantly increased the content of total amino acids and essential amino acids (P<0.05), and adding 0.8% ACM significantly increased the content of polyunsaturated fatty acids (P<0.05). The study indicates that the dietary addition of 0.8%~1.0% ACM can improve serum immune function and meat quality of finishing pigs. [ABSTRACT FROM AUTHOR] |
