摘　　要：[目的]探讨0～9周龄皖西白鹅肠道的发育规律。[方法]以120只1日龄皖西白鹅仔鹅为研究对象,通过饲养试验和屠宰试验研究皖西白鹅肠道重和肠道长度的发育规律。[结果]皖西白鹅早期生长较为缓慢,2～5周龄生长迅速,5周龄左右为生长高峰,随后生长减缓,7～9周龄日增重稳定在25 g/d。肠道发育与体重发育趋势一致,5周龄时达到发育高峰,7周龄时基本发育完善;随周龄的增加,肠道各段长度与肠道总长度的比值均无明显变化。[结论]该研究可为皖西白鹅的生产和种质资源的开发提供理论依据。[Objective] To explore the law of intestinal development of Wanxi white geese at 0-9 weeks old.[Method] A total of 120 Wanxi white geese at 1 day old were selected,and their law of development of intestinal weight and length was studied by feeding test and slaughter test.[Result] The growth of Wanxi white geese was slow in the early age,rapid at the age of 2-5 weeks,peaked at about 5 weeks old,and then slowed.The daily weight gain was around 25 g/d at the age of 7-9 weeks.Intestinal growth also peaked at 5 weeks old and almost developed fully at 7 weeks old.Thus,intestinal growth had a similar law with body weight.With the development,the ratios of the length of each intestinal segment to that of total intestinal tract did not vary largely.[Conclusion] The study provides a theoretical basis for the production and development of germplasm resources of Wanxi white geese.
