To determine the transient effects of weaning on the small intestine, 16 piglets were slaughtered at days 0, 1, 4 and 7 after weaning. Jejunal samples were collected to examine different enzyme activities and mRNA expressions of two stress protein families, namely, heat-shock proteins (HSP) and trefoil factors (TFF). Results showed that the activities of ceruloplasmin, alkaline phosphatase and lactate dehydrogenase, were significantly changed at Day 1 and/or Day 4. The mRNA expressions of HSP10, HSP60 and HSP90 showed a pattern of increased expression with time after weaning. Expression significantly differed between Day 0 and Day 7 after weaning. The mRNA expression of HSP70 was significantly increased on Day 1 only. Similarly, the mRNA expressions of TFF1 and TFF2 were significantly increased on Day 7 compared with those on Day 0. Expression of TFF3 was not affected by time after weaning. In conclusion, the present study indicated that weaning induced transient injury to small intestinal morphology and function. Particularly it changed enzyme activities and gene expression of stress proteins in the small intestine of piglets. At first time, a change in the gene expression of HSP10 and a gene overexpression of TFF1 in the small intestine of piglets after weaning was found.
