One experiment was carried out to evaluate protein sources and levels, and lactose in starter diets, for piglets weaned at 21 days of age. The animals were allotted in a completely randomized design in a factorial 2 x 2 x 2, with type of diets ( dried whey and fish meal + lactose), levels of crude protein (20 and 24%) and piglet weight at weaning (?6.0 and > 6.0kg), in a total of eight treatments and four replications with 14 piglets (7 males and 7 females) each. In the experimental conditions, it can be concluded that among the protein sources tested, the performance of 21 day-age weaned piglets fed fish meal + lactose (FG 1.81) compared was better to dried whey(FG 1.93)m. The level of 24% crude protein was more efficient, mainly in the fish meal + lactose diets (WG 8.91kg x 7.93kg). It is concluded also that the type of diets studied did not influence histologycal parameters and the villous height is a direct funcion of piglets weight.
