Diets for piglets in suckling and post-weaning periods

[摘要] - Two hundred crossbred piglets (Landrace ´ Large White), fed in the period from 14 to 56 days of age, were assigned to a randomized block design with four treatments and five replicates, to evaluate the effects of different diets on the piglets performance, relative and absolute weights of liver and pancreas in suckling and post-weaning periods. The treatments consisted of four diets, that were supplied from 14 to 42 days of age, when were replaced by a simple diet (nursing ration). The results allowed to conclude that all diets containing sources of hight protein quality, like integral dried milk and fish meal, withouth supplementary source of energetic foods, like dried whey when supplied pigs from 14 days to 42 days of age, provide the same results for the pigs weaned to the 28 days of age and receiving simple diets with corn and soybean meal.
