Effect of modified Buzhong Yiqi Decoction on mutton quality and immune function of small-tailed Han sheep

中文摘要英文摘要

试验旨在探究加味补中益气散对羊的肉品质及免疫功能的影响.选取2月龄小尾寒羊公羊羔60只,随机分为5组,每组3个重复,每个重复4只.试验组分别在基础日粮中添加1%、2%和3%的加味补中益气散,商品对照组在基础日粮中添加2%的四胃动力散,空白对照组饲喂基础日粮.预试期9d,正式试验期107 d.结果显示,1%剂量组羊肉总脂肪酸的含量显著高于其他组(P<0.05).与空白对照组相比,2%剂量组羊肉中风味氨基酸和正庚醛含量显著升高(P<0.05),正己醛和正壬醛的含量显著降低(P<0.05);3%剂量组羊肉中必需氨基酸、总氨基酸和1-辛烯-3-醇的含量显著提高(P<0.05),癸酸、硬脂酸含量显著降低(P<0.05).5月龄和6月龄时,各剂量组羊血清中小反刍兽疫抗体水平显著升高(P<0.05).研究表明,加味补中益气散可能通过影响小尾寒羊机体脂肪酸与风味氨基酸代谢来调控羊肉中膻味物质和挥发性风味物质的合成,进而改善羊肉风味,同时在一定程度上增强了肉羊的免疫力.

The experiment aimed to investigate the effects of modified Buzhong Yiqi Decoction on the meat quality and immune function.Sixty male lambs of two-month-old small-tailed Han sheep were randomly divided into five groups,with three replicates in each group and four lambs in each replicate.The experimental group was fed with 1%,2%,and 3%modified Buzhong Yiqi Decoction in the basal diet,the commercial control group was fed with 2%Siweidongli powder in the basal diet,and the blank control group was fed with the basal diet.The pre-test lasted for nine days and the formal test lasted for 107 days.The results showed that the total fatty acid content in 1%dose group was significantly higher than that in other groups(P<0.05).Compared with the blank control group,the contentrations of flavor amino acids and n-heptanal in 2%dose group increased significantly(P<0.05),while the contentrations of n-hexanal and n-nonanal decreased significantly(P<0.05).The contentrations of essential amino acids,total amino acids,and l-octen-3-ol in 3%dose group increased significantly(P<0.05),while the contentrations of decanoic acid and stearic acid decreased significantly(P<0.05).At the ages of five and six months,the antibody levels against peste des petits ruminants in the serum of lambs in all dose groups significantly increased(P<0.05).The study suggests that modified Buzhong Yiqi Decoction may improve the flavor of mutton by affecting the metabolism of fatty acids and flavor amino acids in the bodies of small-tailed Han sheep,regulating the synthesis of mutton odor substances and volatile flavor substances,and simultaneously enhancing the immunity of mutton sheep to a certain extent.
