摘要 为探讨花菜叶饲养肉鹅的可行性和效果,选用同批饲养、体重相近的4周龄浙东白鹅,随机分为花菜叶组、黑麦草组和对照组,分别饲喂(20%花菜叶+80%精料)日粮、(20%黑麦草+80%精料)日粮和100%精料日粮,试验期3周。结果显示:用20%花菜叶替代部分精料,试验鹅体重和补饲精料料重比无显著改变(P>0.05);试验鹅血清中TP、ALB和GLU含量差异不显著(P>0.05);BUN和TG浓度极显著降低(P<0.01),AST活性显著降低(P<0.05),ALT活性有所降低(P>0.05);T3和T4含量显著提高(P<0.05);LDL-C含量与其它组无显著性差异(P>0.05),但HDL-C含量极显著提高(P<0.01)。可见花菜叶可作为肉鹅饲料资源开发利用。 In order to explore the feasibility and effect of raising geese with cauliflower leaves,4-week-old Zhedong white geese with nearly the same body weight were randomly divided into cauliflower group, ryegrass group and control group, and fed for 3 weeks respectively on 20% cauliflower leaves + 80% concentrate,20% ryegrass + 80% concentrate,and 100% concentrate. The results showed that the variations of tested geese in body weight and ratio of body weight to feeding were not significant in the cauliflower group ( P 〉 0.05 ) ; The TP, ALB and Glu contents of the tested geese' s sera had no significant difference (P 〉 0.05 ) ; The BUN and TG concentrations decreased significantly (P 〈 0.01 ), the AST activity decreased significantly (P 〈 0.05 ), and the ALT activity somewhat decreased ( P 〉 0.05 ) ; The T3 and T4 contents increased significantly ( P 〈 0.05 ) ; In addition, the LDL-C content had no significant difference ( P 〉 0. 05 ), but the HDL-C content increased significantly ( P 〈 0.01 ). It was thus clear that cauliflower leaves could be used as a feed resource of geese to be developed and utilized.
