摘要
本研究测定的花生藤、红薯藤与油菜秸秆的粗饲料分级指数(GI)分别为1.48、1.65与0.30,其中红薯藤、花生藤的GI均高于张吉鹍(2004)测定的青干草的GI(1.10),但低于苜蓿干草的GI(1.72)[18],表明红薯藤、花生藤均为山羊的优质秸秆饲料。本研究油菜秸秆的GI要高于张吉鹍(2004)测定的玉米秸秆与谷草的GI(分别为0.20与0.17),低于玉米秸秆青贮的0.42[18],表明油菜秸秆是一种具有开发潜力的肉羊秸秆饲料。
The grading indices(GI) of peanut vine(PV), sweet potato vine(SPV) and rape straw(RS) were 1.48, 1.65 and 0.30, those of SPV and PV were higher than that of hay(1.10) but lower than that(1.72) of alfalfa hay measured by Zhang ji-kun in 2004[18], indicated that SPV and PV were high quality straw feed. And the GI of RS was higher than those of corn straw and millet straw(0.20 and 0.17 respectively), but lower than that(0.42) of corn straw ensile(0.42) determined by Zhang ji-kun in 2004[18], indicated that RS was a straw feed with exploring potential for mutton sheep industry.
