为了探寻复合营养舔砖对山羊作用的内在机制，按２ 个３×３ 的拉丁方设计研究了舔砖对日粮营养物质消化率和氮平衡的影响．结果表明：复合营养舔砖可明显提高山羊的增重速度，山羊补饲舔砖后的日增重比单喂稻草、氨化稻草和野杂干草分别提高了 ３２０６％ ，２４１７％ 和３０２１％ ．补饲舔砖后，山羊对粗饲料中 Ｄ Ｍ， Ｏ Ｍ ， Ｃ Ｐ， Ｎ Ｄ Ｆ 和 Ａ Ｄ Ｆ 的摄入量均有提高；对粗饲料中 Ｄ Ｍ ， Ｏ Ｍ， Ｄ Ｎ Ｆ和 Ａ Ｄ Ｆ 等营养成分的消化率有明显提高，对粗饲料、粗蛋白质的消化率有极显著的提高．补饲舔砖还可明显改善山羊氮平衡，显著增加氮存留量，显著提高氮和蛋白质利...

Two 3×3 latin square experiments were used in the studies. Results obtained showed that multinutrient block (MB) could improve growth rate and feed efficiency of goat. The treatment with MB increased the daily liveweight gain of goat by 32 06%,24 17% and 30 21% over the control fed with rice straw,ammoniated rice straw and hay respectively. It also increased significantly the intake of DM,OM,CP,NDF and ADF in coarse fodder and the digestibility of DM,OM,DNF and ADF in coarse fodder,too. Whats more,a very significant increase of digestibility...
