摘　　要：为了解不同黑麦草添加量对浙东白鹅生长性能、常规养分消化率及屠宰性能的影响,选取1日龄浙东白鹅150只随机分成3组,在相同条件下饲养至3周龄后,分别用5%、10%和20%的黑麦草替代基础日粮进行饲喂,试验期5周。结果显示:鹅日粮中黑麦草添加量在4周龄内以不超过10%为宜,5—7周龄可以增加到10%—20%,第8周添加量可以进一步提高至20%而对体重增加没有显著影响。6周龄浙东白鹅日粮中黑麦草添加量达到20%时,粗脂肪、钙和磷的表观消化率产生显著差异。20%与5%黑麦草添加量对8周龄浙东白鹅盲肠长和肠pH产生了显著影响,对胸肌重产生极显著影响,对其他屠宰性能无显著影响。In order to study the weight gain,slaughter performance and routine nutrient digestibility of Zhe-dong white geese as influenced by the ryegrass amount,a total of 150 one-day-old Zhedong white geese were ran-domly divided into 3 groups,and after raised for 3 weeks in the same conditions the 3 groups were fed for 5 weeks respectively on 3 different rations in which the basal ration was replaced respectively with 5%,10% and 20% of ryegrass.The results showed that it was suitable for the amount of ryegrass added to the basal ration not to be over 10% at the age of 0—4 week,the amount of added ryegrass could be increased to 10%—20% at the age of 5—7 weeks,and the amount could be increased to 20% in the 8th week,which had no significant effects on the weight gain.At the age of 6 weeks the apparent digestibilities of crude fat,calcium and phosphorus in Group 3 were significantly different from those in Groups 1 and 2.At the age of 8 weeks there were significant differences in both length and pH of the cecum between Groups 1 and 3 and a extremely significant difference in the weight of pectorales,but there were no significant differences in other slaughter performances.
