摘要 为研究玉米秸秆和花生秧对肉鹅胃肠道发育的影响,选用2周龄肉鹅180只,随机分为6组,每组3个重复,分别饲喂不同水平玉米秸秆或花生秧日粮。结果表明:在饲粮代谢能和粗蛋白水平相同的条件下,玉米秸秆或花生秧日粮对2~8周龄肉鹅胃肠道长度和胃肠道指数均无显著影响(P〉0.05)。玉米秸秆或花生秧较高组,肉鹅的十二指肠形态各指标均最高,高玉米秸秆组十二肠绒毛长度显著高于低水平组(P〈0.05)。粗纤维水平相同条件下,玉米秸秆或花生秧对2~8周龄肉鹅的胃肠道长度、胃肠道指数及十二指肠肠道形态指标的影响均无显著差异(P〉0.05)。综上,本试验所用玉米秸秆或花生秧添加水平对2~8周龄肉鹅的胃肠道长度及其指数无显著影响,可促进十二指肠道发育。
