Abstract

With the aim to evaluate the embryonic development of Gallus gallus domesticus, hatching eggs were incubated at temperatures of 34.0ºC, 37.5ºC and 40.0ºC and in time periods of 48h; 72h and 96h. In 81 embryos, besides the head-rump length and total weight determination, 6 characteristics were evaluated through morphological scores. Median values that, at the three incubation times, differ from the standard scores, represent accelerated or retarded development. The length and developmental level of embryonic structures, increase with temperature and time elevations, characterizing the interaction in the studied factors, related with the morphogenetic processes.
