| 摘 要： | 在五龙鹅的基础日粮中添加青绿冬牧 70黑麦鲜草,基础日粮∶冬牧 70黑麦=1∶2、1∶3、1∶4,粗纤维的质量分数分别为17.92%、20.40%、22.27%,研究高粗纤维饲料对五龙鹅N平衡及Ca、P消化规律的影响.结果表明,随着冬牧 70黑麦鲜草饲喂量的增加,N沉积量差异不显著,N总消化率逐渐升高,Ca的吸收率逐渐降低,P的吸收率逐渐升高.五龙鹅能够耐受高粗纤维饲粮,其N沉积和Ca、P消化不受影响.

| Abstract: | Dongmu-70 rye in different proportions was fed to 32 healthy mature Wulong geese in 4 groups of random-designed experiment (8 for each) to determine the digestibility of N and Ca as well as P .The result indicated that in the treatment groups, with the increase of crude fiber (CF) concentration the digestibility of N and P increased and the digestibility of Ca decreased. Wulong goose can endure high CF concentration diet and the digestibility of N, Ca and P get no affection. |
