Abstract：This study aimed to investigate the effects of Rumex hanus by.fermented diet on the growth performance,slaughter performance,meat quality,nutrient apparent digestibility,and serum biochemical indices in sheep.Twenty-four 3-month-old fattening sheep were randomly divided into three groups with eight replicates per group and 1 sheep per replicate.Group A(control group)was fed a basal fermented diet.Groups B and C were fed diets in which 5％and 10％of the soybean meal in the basal fermented diet was replaced with fermented Rumex hanus by.,respectively.The pre-test lasted for seven days and the formal test lasted for 90 days.The results showed that the final body weight,average daily gain,and average dry matter intake in Groups B and C were significantly higher than those in Group A(P＜0.05),while the feed-to-gain ratio was significantly lower(P＜0.05).The live weight before slaughter,carcass weight,slaughter rate,and loin eye area in Groups B and C were significantly higher than those in Group A(P＜0.05).The muscle pH at 45 min,pH at 24 h,water-holding capacity,cooking loss rate,and shear force in Groups B and C were significantly lower than those in Group A(P＜0.05).The apparent digestibility of dry matter,crude protein,neutral detergent fiber,and acid detergent fiber in Groups B and C were significantly higher than that in Group A(P＜0.05),and the apparent digestibility of crude fat in Group B was significantly higher than that in Group A(P＜0.05).Serum total protein and globulin concentrations in Groups B and C were significantly higher than those in Group A(P＜0.05),while serum urea nitrogen content was significantly lower(P＜0.05).Serum triglyceride content and alanine aminotransferase activity in Group B were significantly higher than those in other groups(P＜0.05).The study indicates that replacing soybean meal with 5％or 10％Rumex hanus by.in the diet improves growth performance,slaughter performance,and meat quality in sheep.However,from the perspective of serum lipid metabolism and liver metabolism,a 5％substitution is more conducive to promoting protein metabolism and fat deposition.
