摘要
采用套算法进行消化代谢试验研究构树叶的营养价值。结果表明:构树叶的总能、总能表观消化率和表观消化能分别为15.99 MJ/kg、68.10%和10.54 MJ/kg;粗蛋白质含量、表观消化率和可消化粗蛋白质分别为22.97%、76.5%和17.41%;粗脂肪含量、表观消化率和可消化粗脂肪分别为3.20%、30.13%和0.93%;粗纤维含量、表观消化率和可消化粗纤维分别为9.07%、32.61%和2.91%;无氮浸出物含量、表观消化率和可消化无氮浸出物分别为42.24%、83.22%和35.23%。氮沉积率和蛋白质生物学价值分别为61.72%和70.31%。
The nutritive value of leaves of broussonetia papyrifera (LBP) was studied by a digestion-metabolism trial. The results showed that the general energy of the leaves, apparent digestibility and digestible energy of general energy were 15.99 MJ/kg, 68.10% and 10.54 MJ/kg respectively; crude fat content, apparent digestibility and digestible fat were 3.20%, 30.13% and 0.93% respectively; and nitrogen-free extract content, apparent digestibility and digestible nitrogen-free extract were 42.24%, 83.22% and 35.23% respectively. N retention and biological value of apparent protein were 61.72% and 70.31% respectively.
