摘　　要：旨在研究饲粮添加不同比例膨化红枣粉对海南黑山羊的生长性能、屠宰性能、血清抗氧化能力和肉品质的影响。选择体况一致,生理状况相近的海南黑山羊公羊9只,随机分成3组,每组3只,对照组饲喂基础日粮,试验组在饲喂基础日粮的基础上分别添加10%和20%的膨化红枣粉制作的粉料,预试期10 d,正式试验90 d;记录每只羊的采食量、初始体重和末重,采用内源性指示剂法测定海南黑山羊的表观消化率。结果:添加10%和20%膨化红枣粉的海南黑山羊的终末体重、平均日增重和采食量比对照组显著增加,料重比显著降低,均以20%替代量效果明显(P<0.05),而添加膨化红枣粉对海南黑山羊的表观消化率均无显著影响;添加10%和20%膨化红枣粉对海南黑山羊的胴体肌肉重、屠宰率、净肉率的含量有显著性提高,其中以20%替代量效果较好(P<0.05);添加10%和20%膨化红枣粉的海南黑山羊的超氧化物歧化酶和过氧化氢酶含量显著增加,以20%替代量效果较好(P<0.05);膨化红枣粉替代组的剪切力显著下降,以20%的替代组下降明显,熟肉率显著增加(P<0.05),以20%替代量效果显著。综上,在饲粮中添加20%的膨化红枣粉,能较好地提高海南黑山羊的生长性能、屠宰性能、血清抗氧化能力和肉品质。This experiment was to investigate the impact of varying proportions of puffed jujube powder in the diet on the growth perform⁃ance,slaughter performance,serum antioxidant levels,and meat quality of Hainan black goats.Nine healthy male Hainan black goats with the same body condition and similar physiological status were selected and randomly divided into 3 groups,with 3 goats in each group.The control group was fed with basal diet,and the experimental groups were fed with 10%and 20%puffed jujube powder,respectively,on the basis of the basal diet.The preliminary test lasted for 10 days,and the formal experiment lasted for 90 days.During the experiment,the feed intake,as well as the initial and final body weights of each goat,were recorded.The apparent digestibility of the Hainan black goats was as⁃sessed using the endogenous indicator method.The results showed as follows:The final body weight,average daily gain and feed intake of the goats supplemented with 10%and 20%puffed red jujube powder were significantly increased,compared with the control group,while their ratio of feed to gain was significantly decreased.The addition of puffed jujube powder had no significant effect on the apparent digestibility of the Hainan black goats.The addition of 10%and 20%puffed red date powder significantly increased the carcass muscle weight,slaughter rate,net meat rate,and content of the goats,and the replacement amount of 20%was better.The contents of superoxide dismutase and cata⁃lase of Hainan black goats whose diets were supplemented with 10%and 20%puffy jujube powder were significantly increased,and the effect of 20%replacement was better.The shear force of the expanded jujube powder replacement group was significantly decreased,and that of the 20%replacement group was significantly decreased.The cooked meat rate was significantly increased(P<0.05),and the effect of the 20%replacement amount was significant.These results indicated that the growth performance,slaughter performance,serum antioxidant capacity and meat qu
