This experiment was conducted to study the effects of dietary baicalin and coated baicalin on growth performance,slaughter performance and meat quality of fattening Hu sheep.Thirty-six healthy 3-month-old Hu lambs with similar body weight of(33.01±2.68)kg were randomly divided into 3 groups with 4 replicates per group and 3 sheep per replicate.The sheep in the control group were fed a basal diet,and the others in the ex-perimental groups were fed the basal diet supplemented with 0.1％baicalin(baicalin group)and 0.1％coated baicalin(coated baicalin group)(dry matter basis),respectively.The pre-trial period lasted for 15 days and the experimental period lasted for 60 days.The results showed as follows:1)compared with the control group,the average daily gain(ADG)and dry matter intake(DMI)of fattening Hu sheep in baicalin group and coated baicalin group were significantly increased(P＜0.05),and the final body weight and total weight gain in baicalin group were significantly increased(P＜0.05).2)Compared with the control group,the live weight before slaughter and carcass weight of fattening Hu sheep in baicalin group and coated baicalin group were significantly increased(P＜0.05),and the net meat weight and net meat percentage of carcass in baicalin group were significantly increased(P＜0.05).3)Compared with the control group,the serum glucose(GLU)content in baicalin group and coated baicalin group was significantly decreased(P＜0.05),and the serum total protein(TP)and globulin(GLB)contents were significantly increased(P＜0.05).4)Compared with the control group,the drip loss and water loss rate in longissimus dorsi of fattening Hu sheep in baicalin group and coated baicalin group were significantly decreased(P＜0.05);the moisture content in longissimus dorsi in coa-ted baicalin group was significantly decreased(P＜0.05),and the ether extract content in longissimus dorsi was significantly increased(P＜0.05).5)Compared with the control group,the contents of stearic acid and behen-ic acid in longissimus dorsi of fattening Hu sheep in baicalin group and coated baicalin group were significantly decreased(P＜0.05),and the linoleic acid content in longissimus dorsi was significantly increased(P＜0.05);the oleic acid content in longissimus dorsi in coated baicalin group was significantly increased(P＜0.05).6)Compared with the control group,the gross profit per head of fattening Hu sheep in baicalin group was in-creased by 49.58％,while the gross profit per head in coated baicalin group was decreased by 11.69％.In con-clusion,dietary 0.1％baicalin and 0.1％coated baicalin can improve ADG and DMI,slaughter performance and meat quality of fattening Hu sheep;considering the economic benefits,it is recommended to add 0.1％ba-icalin to the diet for fattening Hu sheep.[Chinese Journal of Animal Nutrition,2024,36(11):7161-7172]
