Thirty-five newborn piglets (1.4+-0.2 kg.bw.) were devided into 7 groups of 3 piglets each. First 3 groups were fed with cow colostrum for 1, 3 and 5 days. Another control 3 groups were left with their sows and the last group was the newborn piglet at birth (0 hours). Each piglet was killed and the mucosal samples of the small intestine in different parts (duodenum, upper jejunum, lower jejunum, upper ileum, lower ileum) were collected for RNA analysis. Statistical analysis showed no difference (P0.05) between the control and the treatment groups. However, it was found that the mucosal RNA in every part of the small intestine in the newborn piglet fed cow colostrum, was lower than that of the control groups at the 24 hours after birth. On the third and fifth day after birth, the mucosal RNA in almost every part of the small intestine of the cow colostral fed piglets increased higher than those of their control groups. These results suggested that the cow colostrum, the high concentration and heterologous protein for the piglets, could decrease mucosal RNA of the small intestine of the newborn piglets. This effect could also relate to the process of macromolecular absorption.
