| 摘 要： | 以9头装有永久性瘤胃瘘管的内蒙古半细毛羯羊为试验动物,采用尼龙袋法对玉米淀粉、玉米、麸皮、豆粕、麻粕、棉籽粕、苜蓿干草、羊草、肋麦野豌豆、玉米秸等10种常用饲料的过瘤胃淀粉量及淀粉瘤胃降解率进行了比较研究。结果表明,各种饲料的过瘤胃淀粉量(g/kg)依次为417.85、404.84、226.31、62.04、110.56、108.61、73.50、50.87、47.55、24.43;其淀粉瘤胃降解率%依次为60.95、50.47、61.70、80.19、65.57、61.01、53.15、64.23、70.40、73.65。

| Abstract: | Nine Inner Mongolia semi-fine wool wethers fitted with rumen cannulas were used for the measurement of amounts of rumen bypass starch and degradability in corn starch,maize,wheat bran,soybean meal,flaxseed meal,cottonseed meal,alfalfa hay,grass hay,wild pea,corn stalks by in a nylon bag technique.The results show that the amount of rumen bypass starch(g/kg) in the ten feedstuffs were:417.85,404.84,226.31,62.04,110.56,108.61,73.50,50.87,47.55,24.43 respectively;and the corresponding degradability values were:60.95%,50.47%,61.70%,80.19%,65.57%,61.01%,53.15%,64.23%,70.40%,73.65%? |
