[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

This document is the first white paper published by the government on China＇s rule of law. It contains eight chapters and six appendices to review China＇s achievements on the road to practicing the rule of law in a compre- hensive way, and to expound the official Chinese policy and position on this is- sue. With some essential points inside, the publication of this white paper is of great significance, especially this year, to China＇s rule of law, human rights prog- ress, and its communication and dialogue with the international community.展开更多
