添加王草对鹅生长性能和血液指标的影响

为探讨王草对鹅生长性能及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240只,随机分成4组即对照组饲喂基础日粮,3个王草处理组分别饲喂7.5%、10%和12.5%王草替代基础日粮的饲料,每个组3个重复,每个重复20只鹅,进行2个月的饲养试验。结果表明,添加王草处理显著提高体重、平均日增重和平均日采食量(P0.05),添加10%王草处理组料重比最低(P0.05);添加王草对鹅血液生理指标无显著影响;添加王草处理显著降低了谷丙转氨酶、总蛋白、甘油三酯含量(P0.05),改善了生化指标。综上,鹅日粮中添加王草不会影响鹅的健康,王草粉添加量为10%时效果较好。

Effects of Kinggrass on Growth Performance and Blood Physiological and Biochemical Indexes of Geese

This experiment was conducted to study the effects of kinggrass on growth performance and blood physiological and biochemical indexes of geese.A total of 240 28-day-old Hainan indigenous geese with similar body weight were randomly divided into 4 groups with 3 pens of 20 geese per group and fed for 60 days.Three sets of diets were used in this trail were control diet and diet supplemented with 7.5％,10％ or 12.5％ kinggrass,respectively.The results showed as follows:1) kinggrass diet significantly improved geese's body weight,daily weight gain,daily feed intake (P＜0.05) and Feed intake/gain of group Ⅱ was the lowest (P＜0.05).2) kinggrass diet had no significantly effect on blood Physiological indexes.3) kinggrass diet significantly decreased the GPT,TP and TG content and improved other blood biochemical indexes.In conclusion,kinggrass will not harmful to health of geese,and supplementing 10％ kinggrass on goose's diet could improve.
