| 摘 要： | 以体重相近的三元杂交仔猪为动物模型, 考察仔猪(分为3个处理组)采食由不同比例的支链淀粉(AMP)与直链淀粉(AMO)组成的日粮后日粮中氨基酸(AA)的表观回肠末端(AID)和表观粪便(AFD)消化率的变化.结果表明,日粮中AMP和AMO的比例显著影响仔猪对AA的消化吸收,提高日粮中AMP的含量有助于提高日粮AA的AID值,从而提高仔猪对日粮AA的利用率.

| Abstract: | The present study was conducted to evaluate the effects of different ratioes of amylopectin/amylose in dietary starch on digestibilities of dietary amino acids (AA) in weaning pigs. Results show that consuming dietary starch with different ratioes of amylopectin/amylose would affect the digestibility of AA and high concentration of amylopectin in dietary starch would improve the efficiency of AA in pigs. |
