Abstract

The present work has the objective of evaluating the viability of the process of transfer or not of the eggs in the farm on the effects in the artificial incubation. To evaluate this practice, the productivity indexes of 3,072 eggs were studied, divided into two categories: classified and unclassified eggs. Fertility, hatchability, embryonic mortality and contamination rates were determined. The hatchability and fertility indexes in relation to the total number of eggs were influenced in relation to the classification process (p<0.05). There was a significant statistical difference in the type of process for the embryonic mortality according to the incubation phase. Embryo mortality was lower for the eggs that underwent the classification process. There was no significant statistical difference for the contamination index. The results suggest that eggs that go through the classification process have better hatchability and embryonic mortality rates.
