The experiment was conducted to examine the effect of dietary insulin on the development of gastrointestinal tract in neonatal pigs.Five piglets were anesthetized and sampled within 2~4 hours after birth without suckling and used as newborn control(group N).Ten other piglets from 5 litters were randomly divided into group M(n=5),which were fed cow,and group MI(n=5),which were fed cow milk plus insulin(2.5 mg/L).The piglets of groups M and MI were artificially fed for 3 days and then anesthetized and sampled.Results showed that the small intestinal length in groups MI and M was higher(P0.01 and P0.05,respectively) than in group N.The non-mucosal weight of small intestine in group MI had the tendency to be higher(P=1.148) than in group M.The villus height of small intestine in groups MI and N showed no significant difference(P0.05).The villus heights of distal jejunum and primal ileum in group MI were higher(P0.01 and P0.05,respectively) than that in group M.The villus height/crypt depth of the small intestine in group MI was higher(P0.01 or P0.05) than that in group N.The Villus height/crypt depth of primal and distal jejunum was higher(P0.05 and P0.01,respectively) than that in group M.Collectively,we conclude from the data that dietary affects the intestinal growth and morphology.
