Law of Intestinal Development of Wanxi White Geese at 0-9 Weeks Old
摘要
Abstract
[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.关键词
