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.
