Abstract:

The purpose of this study was to investigate the effects of compound Chinese herbal medicine supplements on growth performance,nutrient apparent digestibility and blood parameters of finishing pigs.The 192 healthy and DYL crossbred finishing pigs with (56.21±1.76) kg body weight of 130 days old were selected and divided into 4 groups with 4 replicates per group and 12 heads per replicate according to the principle of similar body weight and the same proportion of males and females.The levels of compound Chinese herbal medicine in the diets of 4 groups were 0 (control group),650,1 000 and 1 500 mg/kg,respectively.The trial was divided into pre-feeding period (7 d) and formal period (30 d),and growth performance,nutrient apparent digestibility,biochemical indexes,antioxidant indexes and immune indexes in blood of finishing pigs were determined.The results showed that:①Compared with the control group,the 650 mg/kg group could increase the average daily gain and decrease the F/G to some extent (P>0.05).②After adding 650 and 1 500 mg/kg of compound Chinese herbal medicine to the diet,the apparent digestibility of CP was significantly higher than that of the control group (P<0.05),and the apparent digestibility of NDF,ADF,Ca,P did not show difference among the groups (P>0.05).③The addition of 650 mg/kg compound Chinese herbal medicine in the diet significantly increased the serum HDL-C level and GSH-Px activity of finishing pigs (P<0.05),and significantly decreased the serum LDL-C level and MDA content (P<0.05).④The addition of compound Chinese herbal medicine to the diet had no significant effect on the body's immune indexes (P>0.05).In summary,the addition of 650 mg/kg compound Chinese herbal medicine to the diet had a positive effect on the growth performance and nutrient apparent digestibility of finishing pigs,which could improve the blood biochemical indexes of finishing pigs,reduce the content of serum MDA and increase the GSH-Px activity.
