摘　　要：为分析日粮中添加不同比例新鲜砂仁(Amomum villosum)茎叶对雷州黑山羊生长性能和血液生化指标的影响,本研究选择20只雷州黑山羊,随机分为4组(CK、Ⅰ、Ⅱ、Ⅲ),每组5只;对照组饲喂基础饲粮,试验Ⅰ组、试验Ⅱ组、试验Ⅲ组在基础饲粮中分别用5%、10%和20%的新鲜砂仁茎叶等量替代日粮王草,试验期60d。结果表明:试验Ⅰ和试验Ⅱ组雷州黑山羊的平均日采食量(average daily feed intake,ADFI)、平均日增重(average daily gain,ADG)均显著高于CK组和试验Ⅲ组(P<0.05),CK和试验Ⅲ组差异不显著(P>0.05);试验Ⅱ组的料重比(Feedtogain,F/G)显著低于对照组和其他试验组(P<0.05);除了试验Ⅲ组谷丙转移酶(glutamic-pyruvic transaminase,ALT)、碱性磷酸酶(alkaline phosphatase,ALP)显著高于CK组(P<0.05),其他血液生化指标在各组间差异均不显著(P>0.05)。以上结果说明,新鲜砂仁茎叶作为一种中草药粗饲料在雷州黑山羊日粮中适宜添加比例为10%,这为砂仁茎叶饲料化开发利用提供理论基础。To study the effects of different proportions of stems and leaves of Amomum villosum in the diet of Guangdong Leizhou black goats on growth performance and blood biochemical indexes,20 goats were selected and randomly divided into 4 groups (CK,Ⅰ,Ⅱ,and Ⅲ),with 5 black goats per group.The control group (CK) was fed with a standard premixed diet.The test Ⅰ,Ⅱ,and Ⅲ groups were fed with 5 %,10 %,and 20 % of King grass,respectively,which was replaced by an equal quantity of fresh A.villosum along with a constant basal diet.The trial period was 60 days.It was found that there was a significantly higher average daily feed intake (ADFI) and average daily gain (ADG) in the test Ⅰ and Ⅱ and CK groups than in the test Ⅲ group (P < 0.05),but there was no significant difference between the CK and test Ⅲ group (P > 0.05). Feed to gain of the test Ⅱ group was significantly lower than that of the control and other test groups (P < 0.05).The glutamic-pyruvic transaminase (ALT) and alkaline phosphatase (ALP) of the test Ⅲ group was significantly higher than that of the CK group (P < 0.05);other blood biochemical indexes were not significantly different in the other test groups (P > 0.05).In summary,10% was the optimal proportion of stems and leaves of A.villosum,as a Chinese herbal medicine and source of roughage,in the daily diet of Leizhou black goats.The results will provide a theoretical basis for the development and utilization of the stems and leaves of A.villosum as forage.
