An experiment was done to investigate the effect of soybean protein hydrolysate on digestive tract development of 21-day-old weaned piglets by making 2-day-old weaned piglets as the control. The results showed that, compared with the control, pepsin total activity of gastric chyme of piglet in the treatment increased by 3.22%, but the difference was not significant（P＞0.05）, protease total activity of duodenal chyme remarkably increased by 136.05%（P＜0.01）, whereas lipase activity and amylase activity of duodenal chyme decreased（P＜0.01）. The thickness of gastric antrum mucosa, middle duodenum villus height, crypt depth and middle ileum villus height of piglet in the treatment were all significantly higher than those of the control（P＜0.01）, but there was no significant difference in middle duodenum villus, foreside jejunum, middle ileum villus width and villus height/crypt depth of piglet in the treatment when compared with the control.
