摘 要:试验旨在研究复方中草药“藿香龙黄散”对波杂山羊生长性能、屠宰性能和肉品质的影响。选取3月龄波杂山羊40只,随机分为4组,每组10个重复,每个重复1只羊,对照组山羊饲喂基础日粮,试验Ⅰ组、试验Ⅱ组、试验Ⅲ组分别在基础日粮中添加1.0%、2.0%、4.0%藿香龙黄散。试验期60 d。结果显示:与对照组相比,试验Ⅰ组、试验Ⅱ组、试验Ⅲ组山羊的末重和平均日增重提高(P<0.05),料重比显著降低(P<0.05);试验Ⅱ组山羊的平均日采食量显著提高(P<0.05)。试验Ⅱ组山羊的胴体重、屠宰率、胴体净肉率和眼肌面积显著高于对照组(P<0.05);试验Ⅱ组山羊羊肉的剪切力和滴水损失率显著低于对照组(P<0.05),试验Ⅲ组山羊羊肉的剪切力显著低于对照组(P<0.05)。研究表明,藿香龙黄散能够提高波杂羊的生长性能和屠宰性能,改善波杂羊的肉品质,且日粮中添加2%藿香龙黄散效果较好。The experiment was to study the effect of compound Chinese herbal medicine ’Huoxiang longhuang powder’ on growth performance, slaughter performance and meat quality of Boza goat. 40 three-month-old Boza goats were randomly divided into four groups, with ten replicates in each group and one goat in replicate. The goats in control group were fed with a basal diet, and the goats in test group Ⅰ, group Ⅱ and group Ⅲ were fed with a basal diet supplemented with 1.0%, 2.0% and 4.0% Huoxiang longhuang powder, respectively. The experiment lasted for 60 d. The results showed that compared with control group, the final weight and average daily gain of goats in group Ⅰ, group Ⅱ and group Ⅲwere increased(P<0.05), the feed to gain ratio was significantly decreased(P<0.05). The average daily feed intake of group Ⅱ was significantly increased(P<0.05). The carcass weight, slaughter percentage, carcass net meat percentage and eye muscle area of group Ⅱ were significantly higher than those of control group(P<0.05). The shear force and drip loss rate of goat meat in group Ⅱ were significantly lower than those in control group(P<0.05), and the shear force of goat meat in group Ⅲ was significantly lower than that in control group(P<0.05). The study indicates that Huoxiang longhuang powder can improve the growth performance and slaughter performance of Boza goat, improve the quality of Boza goat meat, and 2% Huoxiang longhuang powder in diet has a better effect.
