摘要
测定了杂交构树Broussonetia papyrifera叶的常规营养成分、微量元素、氨基酸等,其中粗蛋白为26.05%,钙为3.35%,铁为247.09 mg/kg。与苜蓿Medicago sativa草粉和豆粕相比,粗蛋白含量豆粕>杂交构树叶>苜蓿草粉。而中性洗涤纤维、酸性洗涤纤维含量则相反。铁、锰、锌、钴、碘等矿物元素含量高于苜蓿草粉与豆粕,检测的多数氨基酸含量较苜蓿草粉高。综合各项指标,可以认为杂交构树叶是一种富含蛋白、钙、铁的很好的饲料原料,可以在草食动物日粮中应用。
The contents of nutrients in leaf of hybrid Broussonetia papyrifera, including routine nutrients, trace elements, amino acids were determined. The result showed that the contents of crude protein, Ca and Fe were 26.05%, 3.35% and 247.09 mg/kg respectively. Its CP content was higher than that of alfalfa mill and less than that of soybean meal, and its contents of Fe, Mn, Zn, Co and I were higher than alfalfa and soybean meal. The contents of most amino acids were higher than that of alfalfa. So it could be concluded that it was an excellent feed resource and could be used as feed for herbivores.
