木薯叶粉对鹅生长性能和血液生理生化指标的影响

本试验旨在探索木薯叶粉对鹅生长性能和血液生理生化指标的影响。选用28日龄体重相近、健康的海南本地杂交鹅108只,随机分成3组,每个组6个重复,每个重复6只鹅。Ⅰ组(对照组)饲喂基础饲粮,Ⅱ组、Ⅲ组饲粮中分别添加5%、10%木薯叶粉。试验期42 d。结果表明:1)Ⅱ组、Ⅲ组体重和平均日增重显著高于Ⅰ组(P0.05),Ⅲ组平均日采食量显著高于Ⅰ组、Ⅱ组(P0.05),Ⅱ组料重比显著低于Ⅰ组、Ⅲ组(P0.05)。2)Ⅱ组血液平均红细胞体积显著高于Ⅲ组(P0.05),Ⅲ组血液红细胞体积分布宽度显著高于Ⅰ组和Ⅱ组(P0.05),其他血液生理指标各组间无显著差异(P0.05)。3)Ⅲ组血液谷丙转氨酶活性显著低于Ⅰ组(P0.05),Ⅰ组、Ⅱ组血液白蛋白含量显著高于Ⅲ组(P0.05),Ⅱ组血液葡萄糖含量显著高于Ⅰ组(P0.05),其他血液生化指标各组间无显著差异(P0.05)。综上所述,饲粮中添加木薯叶粉能提高鹅生长性能,不会影响鹅的健康,木薯叶粉添加量为5%时效果较好。

Effects of Cassava Leaf Meal on Growth Performance and Blood Physiological and Biochemical Indexes of Geese

This experiment was conducted to study the effects of cassava leaf meal on growth performance and blood physiological and biochemical indexes of geese. A total of 108 healthy 28-day-old Hainan indigenous geese with similar body weight were randomly divided into 3 groups with 6 replicates per group and 6 geese per replicate. Geese in the group Ⅰ ( control group) were fed a basal diet, and the others were fed diets supple-mented with 5% ( group Ⅱ) and 10% cassava leaf meal ( group Ⅲ) , respectively. The experiment lasted for 42 days. The results showed as follows:1) the body weight and average daily gain of groups Ⅱ and Ⅲ were significantly higher than those of group Ⅰ (P<0.05), the average daily feed intake of group Ⅲ was signifi-cantly higher than that of groupsⅠandⅡ( P<0.05) , the feed to gain ratio of groupⅡwas significantly low-er than that of groups Ⅰ and Ⅲ ( P<0.05) . 2) The blood mean corpuscular volume of group Ⅱ was signifi-cantly higher than that of group Ⅲ (P<0.05), the red blood cell distribution width of group Ⅲ was signifi-cantly higher than that of groups Ⅰ and Ⅱ (P<0.05), and there were no significantly differences on other blood physiological indexes among all groups ( P>0.05) . 3) The blood glutamic-pyruvic transaminase activity of group Ⅲ was significantly lower than that of group Ⅰ ( P<0.05) , the blood albumin content of groups Ⅰand Ⅱ was significantly higher than that of group Ⅲ (P<0.05), the blood glucose content of group Ⅱ was significantly higher than that of groupⅠ( P<0.05) , and there were no significantly differences on other blood biochemical indexes among all groups ( P>0.05) . In conclusion, diet supplemented with cassava leaf meal can improve the growth performance of geese, and is not harmful to health. The suitable supplemental level of cas-sava leaf meal is 5%.
