摘　　要：对 18个饲料用水稻样品的稻谷和糙米的常规营养成分、氨基酸组成和有效能值进行了分析和测定。稻谷和糙米含蛋白质分别为 (8.85± 1.2 3) % ,(10 .35± 1.33) % ,含总能分别为 (15 .83± 0 .2 8) MJ/kg,(15 .95± 0 .2 0 ) MJ/kg,含消化能10 .2 8MJ/kg和 13.48MJ/kg。稻谷的养分消化率明显低于糙米的相应值。主要是由于稻谷含粗纤维 8.94% ,而糙米的相应值为 1.19%。稻谷和糙米分别含赖氨酸 0 .2 9%和 0 .44 % ,蛋氨酸 0 .10 %和 0 .18% ,苏氨酸 0 .2 6 %和 0 .30 %。用作猪饲料时 ,赖氨酸是第一限制性氨基酸 ,苏氨酸是第二限制性氨基酸 ,异亮氨酸是第三限制性氨基酸。The nutrient content, amino acid content and nutrient digestibility of rice grain and brown rice were investigated with 18 rice cultivars. The average dry matter, crude protein and gross energy in rice grain and brown rice are (87.24±0 30)%, (87.39±0.32)%; (8.85±1.23)%, (10.35±1.33)%; (15.83±0.28) MJ/kg, (15.95±0.20) MJ/kg. The digestible energy of rice grain and brown rice is 10.28 MJ/kg and 13.48 MJ/kg respectively. It was shown that the fiber in rice grain is the main factor for lower nutrient digestibility. The amino acid content of rice grain and brown rice are 0.29% and 0 44% for lysine, 0.10% and 0.18% for methionine and 0.26% and 0.30% for threonine. As a swine feed, the first limiting amino acid of brown rice in lysine, threonine is the second one.
