饲粮添加膨化红枣粉对海南黑山羊生产性能及肉品质的影响
Effects of dietary expanded jujube powder on growth performance and meat quality of Hainan black goats
摘要
Abstract
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 quality of Hainan black goats were improved by adding 20%puffed red date powder to their diet.关键词
