Abstract: The study was carried out to investigate the intestinal development law of Yangzhou geese from 0 to 10 weeks.A total of 189 only one-day-old Yangzhou geese as the research object were randomly allocated into 7 replicates and each had 27 geese.Researched the development law of intestinal weight and length of Yangzhou geese by feeding and slaughtering experiments.The results showed that Yangzhou geese grow fast in 1 to 4 weeks and the ADG reached the peak at the fourth week or so,then stayed in a relatively steady level,73 g/d,between 4 to 7 weeks.Intestinal development was consistent with the trend of ADG and it was basic well development at the sixth week.The ratio of the intestinal paragraphs length to the total length had no significant influence in the period of feeding time.This study provided basic theory for the production and resource development of Yangzhou geese.
