This study aimed to evaluate the effect of age and lineage of layers breeders light and semi heavy on the quality of the egg, the pinto newly eclodido and performance of incubation. 3,456 eggs were used for breeding light (Dekalb White) and semi heavy (Bovans Goldline) in three different ages (young, old and middle age). The experiment was divided into two stages, at first we evaluate the characteristics of the eggs of a sample of 360 eggs (60 per treatment). In the second stage evaluated the performance of chicks hatching and quality of a sample of 3,096 eggs (516 per treatment). It was observed that the quality of the shell fell and the weight of the egg increased with the increase of age of the birds. The layers breeders Dekalb White egg...
