| 摘 要： | The experiment was conducted to study the effects of fermented soybean residues on growth performance, apparent nutrient digestibility, meat quality and blood physiological indexes of Hu sheep, and to investigate the value of fermented soybean residues in the production of meat sheep. In the present study, twenty-one healthy male Hu sheep with similar body weight were selected and randomly allocated into a basal diet （control） group, a soybean residue group （basal diet+20% soybean residue, SR） or a fermented soybean residues group （basal diet+20% fermented soybean residues, FSR）, with 7 animals in each group. The experiment lasted for 49 days, including a 7-day adaptation period. The results were as follows: 1）Compared with the control and SR groups, addition of 20% fermented soybean residues in the diet （FSR） significantly increased the average daily weight gain of Hu sheep （P< 0.05） and significantly reduced the weight gain cost （P<0.05）. 2） The apparent digestibility of dry matter （DM）, crude protein （CP） and neutral detergent fiber （NDF） of Hu sheep in the fermented soybean residues group was significantly higher than that in other groups （P<0.05）. 3） Compared with the SR group, the carcass weight of the FSR group was increased （P<0.05）, while the dressing percentage, meat redness values of the FSR group were greater than those of the other groups （P<0.05）, and the drip loss was lower than other groups （P<0.05）. 4） Compared with the control and SR groups, the serum total protein content of the FSR group was increased （P< 0.05）, and the urea nitrogen content was reduced （P<0.05）. Compared with the SR group, the serum albumin content of the FSR group was increased significantly （P<0.05）. In conclusion, the addition of fermented soybean residues in the diet significantly improved the average daily gain of Hu sheep, reduced the feed cost, improved the apparent digestibility of DM, CP and NDF, and improved the meat quality and serum biochemical indexes. © 2022 Editorial Office of Acta Prataculturae Sinica.
