[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. [ Re- sult] The growth of Wanxi white geese was slow in the early age, rapid at the age of 2 -5 wk, peaked at about 5 weeks old, and then slowed. The daily weight gain was around 25 g/d at the age of 7 -9 wk. 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.展开更多
