野生经济植物资源橡籽仁可利用价值的研究

以京白种鸡作鸡作试验动，以玉米、稻谷作对照，采用鸡真代谢能（ＴＭＥ）法研究野生经济植物资源橡胶籽仁的可利用营养价值。结果表明，橡籽仁１ｋｇ含量总能（ＧＥ）１６．５３ＭＪ，表观代谢能（ＡＭＥ）１１．１３ＭＪ，真代谢能（ＴＭＥ）１１．６６ＭＪ，，含粗蛋白（ＣＰ）１０．６３％，ＣＰ的表观利用率（ＣＰＡＡ）４５．５５％，真利用率（ＣＰＴＡ）４９．８３％，１７种氨基酸（ＡＡ）总含量９．２３％，必需氨基酸（Ｅ

Utilizable value of wild economic plant resourceacorn kernel

Peking whites breeding hens were selected. Using true metabolizable energy method (TME) to evaluate the available nutritive value of acorn kernel, while maize and rice were used as control. The results showed that the contents of gross energy (GE), apparent metabolizable energy (AME), true metabolizable energy (TME) and crude protein (CP) in the acorn kernel were 16.53 mg/kg-1, 11.13 mg.kg-1, 11.66 mg.kg-1 and 10.63%, respectively. The apparent availability and true availability of crude protein were 45.55% and 49.83%. The gross content of 17 amino acids, essential amino acids and semiessential amino acids were 9.23% and 4.84%. The true availability of amino acid and the content of true available amino acid were 60.85% and 6.09%. The contents of tannin and hydrocyanic acid were 4.55% and 0.98% in acorn kernel. The available nutritive value of acorn kernel is similar to maize or slightly lower, but slightly higher than that of rice. Acorn kernel is a wild economic plant resource to exploit and utilize but it contains higher tannin and hydrocyanic acid.
