Temperature is one of the physical factors that determine the success of incubation. Keywords: Incubation, hatchability, mortality, temperature, water loss. Our results show that, under conditions of daily incubation of eggs in the same incubator, higher hatching rate can be obtained using temperatures between 35.5✬ and 36.5✬ incubation temperature is inversely proportional to incubation length, and absolute and relative weights of partridge chicks are not affected by incubation temperature. Early embryonic mortality increased at low temperatures (36.5✬). There was no difference among incubation temperatures in absolute and relative hatchling weights. ![]() Water loss was lower in eggs incubated at low temperatures as compared to high temperatures. Incubation length and temperature were inversely proportional. The highest hatching percentage was obtained between 35.5 and 36.5✬. Jaboticabal, SP aim of this study was to determine the effects of incubation temperature (34.5 35.5 36.5 37.5 and 38.5✬), on incubation period, embryonic mortality, hatching rate, water loss and chick weight at hatch, using daily incubation of partridge (Rhynchotus rufescens) eggs.
