| 摘 要： | 选用大尾寒羊妊娠及空怀母羊各６只，进行氮平衡试验。结果表明，大尾寒羊妊娠并不能导致其采食量显著提高；妊娠大尾寒羊与空怀母羊相比，蛋白质的沉积效率显著提高（Ｐ＜０．０５）；大尾寒羊妊娠期可消化粗蛋白的维持需要量（ＲＤＣＰｍ）可以由下述公式求得：ＲＤＣＰｍ＝２．４３Ｗ０．７５（ｇ／ｄ）式中：Ｗ０．７５为代谢体重（ｋｇ）

| Abstract: | Select 6 pregnant sheep and 6 nongravid sheep,adopt N-balance experiment.The result shows that the fat-tail sheep in pregnancy period will not lead to the raising of intake significantly;that when the pregnancy fat-tail sheep is compared with the nongravid sheep,the deposit rate of protein raise significantly;and that total digestable protein requirement of the fat-tail sheep in pregnancy period can be calculated with the following eguation. RDCPm=2.43W 0.75 (g/d) Postrues W 0.75 :metabolizable weight(kelograte) |
