Two experiments were conducted to determine the effect of age at weaning on the performance of piglets. In each experiment 240 pigs were weaned at either 2 or 3 week of age ad their performance was measured up to 70 days of age. In experiment 1, there were not significant (P0.05) differences from weaning to 28 days of age in body weight gain or feed consumption for piglets weaned at 14 or 21 days of age. However, 14 days-weaned piglets had better feed conversion than the 21 days-weaned pigs. Furthermore, 14 days-weaned pigs showed higher body weight gain, feed consumption and better feed conversion from 28 to 42 days and from 43 to 70 days of age. However, only feed conversion showed a significant (P0.05) difference from weaning to 70 days of age. In experiment 2, there were differences in body weight gain, feed consumption and feed conversion from weaning to 28 days of age, in favor of the 14 days-weaned pigs. There were no significant differences (P0.05) in using a pre-starter diet containing 25% lactose per two weeks or two pre-starters diets: one containing 25% from 14 to 21 days and other with 20% lactose, from 22 to 28 days of age. In conclusion, it is possible to obtain a good performance in early-weaning piglets fed on high digestible diets, containing dairy ingredients (e.g. 20% lactose) in order to replace the maternal milk.
