葛根素对西门塔尔牛生产性能、肉品质和血清抗氧化能力的影响OA

This study aimed to analyze the effects of puerarin on the production performance,meat quality,and serum antioxidant capacity of Simmental cattle.Forty-eight healthy,disease-free Simmental bulls with an initial body weight of(380.25±15.28)kg were selected as test subjects.A single-factor randomized design was used,and the bulls were randomly assigned to four treatment groups based on similar initial body weights,with three replicates per group and four bulls per replicate.The control group was fed only the basal diet without puerarin;the three experimental groups were:P 0.02 group fed the basal diet with 0.02%puerarin;P 0.04 group fed the basal diet with 0.04%puerarin;P 0.06 group fed the basal diet with 0.06%puerarin.The pre-trial period lasted 15 days,and the formal trial period lasted 75 days.The results showed that compared with the control group:1)the final body weights of the P 0.04 and P 0.06 groups increased by 4.15%and 4.36%(P＜0.05),respectively;average daily gain(ADG)increased by 14.01%and 15.92%,and feed/gain ratio(F/G)decreased by 11.46%and 12.73%(P＜0.05);2)muscle shear force decreased by 15.01%and 15.67%(P＜0.05)in the P 0.04 and P 0.06 groups,respectively;marbling scores showed an increasing trend with puerarin addition,and the scores of the P 0.04 and P 0.06 groups increased significantly(P＜0.05);among meat color indices,the a* values of the P 0.04 and P 0.06 groups increased significantly(P＜0.05);3)serum SOD content increased by 21.76%and 23.35%,and T-AOC content increased by 29.98%and 27.79%in the P 0.04 and P 0.06 groups(P＜0.05);MDA content decreased significantly in the P 0.02,P 0.04,and P 0.06 groups(P＜0.05),with the largest decrease of 28.85%in the P 0.04 group.In conclusion,adding puerarin to the diet can improve the growth performance of Simmental cattle,enhance meat quality,and increase antioxidant capacity.Under the conditions of this experiment,the suitable amount of puerarin in the diet of Simmental cattle is 0.04%.
