摘　　要：为研究发酵饲料对湖羊生长性能、屠宰性能、肉品质及血清免疫指标的影响,试验选取3月龄,体重为30 kg左右的健康湖羊公羔40只,随机分为2组,每组2个重复,每个重复10只。试验组在基础饲粮中添加10%的发酵饲料,对照组饲喂基础饲粮,预试期7 d,正试期90 d。结果表明:与对照组相比,湖羊的终末体重、平均日增重分别提高4.13%、12.55%,料重比降低8.51%;宰前活重、胴体重、净肉重、屠宰率和净肉率分别提高4.36%、12.77%、18.23%、8.10%和4.97%;肌肉剪切力降低17.72%,肌间脂肪含量增加26.35%;血清免疫球蛋白G(IgG)含量增加8.87%,白细胞介素4(IL-4)含量增加16.06%,肿瘤坏死因子α(TNF-α)含量降低9.64%。综上所述,在本试验条件下,基础饲粮中添加10%的发酵饲料,能显著增加湖羊的日增重,降低料重比,提高免疫水平和抗炎能力,改善肉品质。This study was conducted to explore the effects of fermented feed on growth performance,slaughter performance,meat quality and serum immune indexes of Hu sheep.Forty healthy male Hu sheep lambs,aged 3 months and weighing about 30 kg,were selected in a completely randomized design with 2 replicates in each group and 10 lambs in each replicate.The experimental group was fed with basal diet supplemented with 10%fermented feed,while the control group was fed with basal diet.There was a 7-day pre-test period and a 90-day test period.The results showed that comoared with the control group,the final body weight,average daily gain of Hu sheep increased by 4.13%,11.14%and the feed/body weight ratio decreased by 8.51%,respectively;The live weight before slaughter,carcass weight,net meat weight,dressing percentage and net meat percentage increased 4.36%,12.77%,18.23%,8.10%and 4.97%respectively;The shear force decreased by 17.72%,and the intramuscular fat content increased by 26.35%;Serum IgG and IL-4 levels increased by 8.87%and 16.06%respectively,and TNF-αlevel decreased by 9.64%.In summary,under the conditions of this experiment,adding 10%fermented feed to the basic diet can significantly increase the daily gain,reduce the feed/body weight ratio,improve the immune level and anti-inflammatory ability,and improve the meat quality of Hu sheep.
