为了探讨日粮中添加不同水平的果胶酶对鹅纤维及钙(Ca)、磷(P)代谢的影响,选取24只24月龄的健康五龙鹅,随机分为4组,日粮中果胶酶添加水平分别为0%, 0.1%,0.2%,0.3%,采用全收粪法进行代谢试验.结果表明:在代谢能(ME)和粗蛋白(CP)摄入量基本一致的条件下,随着果胶酶添加水平的提高,粗纤维(CF)、中性洗涤纤维(NDF)、酸性洗涤纤维(ADF)的消化率分别为20.55%～37.59%,38.74%～55.62%,34.03%～47.98%,钙、磷的表观消化率分别比对照组提高1.81%～7.04%和5.51%～8.38%.说明在日粮中添加适量的果胶酶制剂能够提高鹅对纤维及钙、磷的消化率.

In order to discuss the effect of different levels of dietary supplemental Pectinase on digestion and absorption of Ca, P and fiber in geese, twenty-four-month-old Wulong geese were selected and divided into four groups at random. The proportion of Pectinase in each experiment diet was 0, 0.1%, 0.2% and 0.3% . Total feces collection method was adopted to determine the nutrients in feed and feees to confirm their digestions. The results showed that, under the same content of CP and ME, with the increase of Pectinase content, the digestion of CF, NDF and ADF was 20.55%-37.59%, 38.74%-55.62% and 34.03%-47.98% respectively; The digestibility of Ca and P increased by 1.81%-7.04% and 5.51%-8.38% compared to the control group. So, the appropriate dietary addition of Pectinase could improve the digestibility of Ca, P and fiber in geese.
