摘要:

为研究高精料中添加苦豆子对育肥羔羊生长性能和血清生化指标的影响,选取32只健康、体重在(25.7±2.17) kg的杜蒙杂交公羔羊,随机分为4组,每组8个重复,试验羔羊单笼饲养,自由饮水和采食。对照组饲喂基础饲粮,T1、T2和T3组在对照组的基础上分别添加0.1%、0.3%和0.5%的苦豆子。试验预试期15 d,正试期60 d。试验结果表明:试验第0~30天,T1组的阶段日增重(SDG)与T3组相比显著升高(P<0.05);第30~60天,T2组的阶段日采食量(SDFI)与对照组相比显著升高(P<0.05)。与对照组相比,T1组谷草转氨酶(AST)和乳酸脱氢酶(LDH)的含量显著升高,而直接胆红素(DBIL)的含量显著降低(P<0.05);第30天时,T2组碱性磷酸酶(ALP)和白蛋白(ALB)的含量显著升高(P<0.05),第60天时,总蛋白(TP)和球蛋白(GLO)的含量显著或极显著升高(P<0.05或P<0.01)。综上所述,在高精饲粮中适量添加苦豆子可促进羔羊的生长,改善羔羊的血液生化状态,且0.1%~0.3%的添加效果较好。

Abstract:

To investigate the effects of adding Sophora alopecuroides to high grain diet on growth performance and serum biochemical indexes of Dumeng lambs, a total of 32 healthy Dumont lambs weighing about (25.7±2.17)kg were randomly divided into 4 groups with 8 replicates in each group. The control group was fed with basal diet, and the T1,T2 and T3 groups were fed with 0.1%,0.3% and 0.5% Sophora alopecuroides, respectively.The pre-test period was 15 days, and the positive test period was 60 days.The results showed as follows: On the 0-30th day of the experiment, the stage daily gain (SDG) of T1 group was significantly (P<0.05) higher than that of T3 group. From 30th to 60th day, the stage daily feed intake (SDFI) of T2 group was significantly (P<0.05) higher than that of control group. Compared with the control group, the concentration of aspartate aminotransferase (AST) and lactate dehydrogenase (LDH) in T1 group increased significantly, while the concentration of direct bilirubin (DBIL) decreased significantly (P<0.05). On the 30th day, the contents of alkaline phosphatase (ALP) and albumin (ALB) in T2 group increased significantly (P<0.05), and on the 60th day, the contents of total protein (TP) and globulin (GLO) increased significantly (P<0.05 or P<0.01). It was concluded that adding proper amount of Sophora alopecuroides in high grain diet could promote the growth performance of lambs,improve the blood biochemical state of sheep, and the effect of adding 0.1%-0.3% Sophora alopecuroides was better.
