Abstract

In order to evaluate the effect of pre-incubation storage conditions on embryonic development and chick quality of Camperos breeders, 320 hatching eggs were selected. Before the incubation, they were kept for 4 days at a controlled storage and environment. Then, were kept for 21 days in the incubation process with the same technological conditions. Bioproductive performance on biological controls at 6, 11 and 18 days and at 21 days in hatchers were determined. Embryonic mortality and broken eggs were unchanged (p>0.05) during all the experiment. Also, at 6 days, clear eggs and the embryos with blood rings, tremulous air chamber and normal development and weak were not modified (p>0.05). Furthermore, at 11 days, the storage conditions did not affect the embryos with closed allantois and open (p>0.05). Similarly, at 18 days, the embryonic mortality and with and without air chamber head did not change according the pre-incubation storage conditions (p>0.05). In hatchers (21 days) the hatched chicks, first and second chicks showed no significant differences between treatments (p>0.05). These findings indicate that pre-incubation storage at environment temperature did not affect the embryonic development and chick quality of Camperos breeders on biological controls (6, 11 and 18 days) and hatchers (21 days), respectively.
