This study analyzed the effects of the post-hatch fasting on the body weight and heart, liver and yolk sac weights in chicks from light and heavy eggs produced by young (29 w. old) and old (60 w. old) breeders. The analysis allowed testing for the effects of fasting (food ad libitum, fasting of food and fasting of water and food), egg weight (light and heavy), fasting time (24, 48 and 72 hours) and their interactions. Fasting affected the body weight and organ weights. Chicks from heavier eggs lost more weight and presented quicker absorption of yolk sac than the chicks from light eggs. The negative effects of the post-hatch fasting did not begin simultaneously in the analyzed parameters. The body weights and liver weights were influenced at 24 h, while the heart weights were affected at 72 h.KEY WORDS: Body weight, breeder age, fasting, organs.
