Resumo
Two experiments were carried out to evaluate hydrating agents to newly hatched chicks from breeders
in early production life. The first experiment studied the effect of commercial hydrating agents in pre-lodging
phase in chicks from breeders with 25 weeks of age and submitted to two intervals between hatching and lodging
(0 and 48 hours). Agent did not show any favorable effects on dehydration, mortality and performance until
21 days of age. In he second experiment, sodium bicarbonate was used as hydrating agent. The solution was
supplied for 24 hours, after 0, 24 and 48 hours intervals between hatching and lodging, to chicks from breeder of
27 weeks of age. The intestinal integrity increased, based on intestinal density and organ weight increment
obtained with electrolytes supplementation. As the interval between hatching and lodging increased, the yolk
sac decreased. In both experiments, the interval increasing between hatching and lodging promoted higher
dehydration and mortality incidence, but performance was better at 21 days of age.
