Effects of Adding Different Rations of Qianjinqiao San on Feeding Performance of Finishing Pigs
This study aimed to investigate the effects of Fagopyrum dibotrys Qian Zhong extract(Qianjinqiao San)on growth performance,carcass traits,meat quality,blood biochemical indexes,antioxidant indexes and immune indexes of finishing pigs,and to explore its application effect on finishing pigs.A total of 24 fattening pigs with similar body weights(Duroc×Landrace×Large White)were randomly divided into 4 groups with 3 replicates per group and 2 pigs per replicate.The control group(R1)was fed a farage-based diet,and pigs in the experimental groups(R2,R3 and R4)were fed the basal diet supplemented with 0.3％,0.6％ and 1.2％ Qianjinqiao San.The experiment lasted for 70 days.The results indicated that compared to the R1 group,there were no significant differences in average daily gain(ADG),average daily feed intake(ADFI),and feed-to-gain ratio(F/G)among finishing pigs in groups R2,R3,and R4(P>0.05).Furthermore,the contents of umami amino acids,saturated fatty acids,monounsaturated fatty acids in muscle tissues across different groups did not show significant variation either(P>0.05);the amount of total polyunsaturated fatty acids in R3 group were significantly reduced(P<0.05).There were no significant difference in the slaughter rate,backfat thickness,pH1h,pH24 h,eye muscle area,cooked meat yield,and intramuscular fat content among the different proportion groups of Qianjinqiao San(P>0.05).In comparison to the R1 group,blood urea nitrogen levels(BUN)in the R2 group was significantly lower(P<0.05).Moreover,serum activities of catalase(CAT)and total antioxidant capacity(T-AOC)were significantly increased in both the R3 and R4 groups(P<0.05);additionally superoxide dismutase(SOD)activity levels increased by approximately 8.04％,2.66％ and 9.91％ respectively across groups R2,R3,and R4(P>0.05).The contents of immunoglobulin A(IgA),immunoglobulin G(IgG),immunoglobulin M(IgM)in the serum of R3 and R4 groups were significantly increased(P<0.05);the levels of interferon-γ(IFN-γ)in all test groups were higher than those in the control group,with R2 group showing the most significant increase of 37.43％ (P<0.05).In conclusion,the supplementation of Qianjinqiao San at concentrations ranging from 0.3％ to 1.2％ during the late fattening period does not significantly impact growth performance,carcass characteristics,or meat quality.However,it can enhance serum antioxidant capacity and improve body immunity to a certain extent.
