Incubation temperature profiles were: Control (day 0-4: 37.8°C, day 5-9: 37.2°C, day 10-11: 37.0°C, day 12-13: 36.8°C), moderately high (day 0-4: 38.5°C, day 5-9: 38.2°C, day 10-11: 37.5°C, day 12-13: 37.0°C) and extremely high (day 0-4: 39.5°C, day 5-9: 39.0°C, day 10-11: 38.0°C, day 12-13: 37.5°C). The general linear model procedure in Minitab 17 was used to analyze data, whereas the mean separation was conducted using Fisher's LSD test (p}, journal = {American Journal of Animal and Veterinary Sciences}, publisher = {Science Publications} }
