title: Hatchability of bobwhite quail eggs incubated in various temperature combinations.
abstract: Five experiments were conducted to compare the effects of various incubation temperature combinations on the hatchability of Bobwhite quail eggs. A starting incubation temperature of 40.6 C resulted in numerically lower hatchability. Incubation at 37.5 C resulted in a greater number of pipped, unhatched eggs, and a later, less uniform hatch. Temperatures during the hatching period (22 to 25 days of incubation) of 36.9 C and 38.1 C resulted in lower hatchability than the hatching temperature of 37.5 C.
