摘　　要：在日粮粗蛋白质及泌乳净能相同的情况下，奶山羊采食Ｆｅ、Ｃｕ、Ｚｎ、Ｉ、Ｃｏ及辣椒粉含量不同的Ａ、Ｂ、Ｃ三种复合非蛋白氮饲料。对比试验结果表明，Ｂ饲料的产奶量、饲料转化率及经济效益分别比Ａ、Ｃ组平均提高１０．８２％（Ｐ＜０．０５）、１０．９５％（Ｐ＜０．１０）及３３．０７％。３种饲料均不影响常规乳成分含量（Ｐ＞０．０５），但鲜奶中主要微量元素含量因饲料不同而异（Ｐ＜０．０５或Ｐ＜０．１０）。通常不需给泌乳羊补充Ｆｅ和辣椒粉。Three different compound non一protein nitrogen feeds(A,BandC)were testedin this study.Thecontentsof iron,copper , cobalt,iondine,Zinc and chilli powder were different inA,B and C,while the contents of other nutrients were the same.The milk yield, feed efficiencyand net income of feed Bwere increased l0. 82%(P<0. 05) , 10. 95%(P<0.10) and 33. 07%compared withAandC, respectively.Routine nutrient contents in fresh milk were not affectedbyA,B and C,while the contents of main trace elements in fresh milk varied unregularly(P<0.05or P<0.10).It was suggested that feed Bbe、the most efficient oneamongA,Band Canditbe unnecessary to add iron and chilli powder to dairy goats。
