This study was performed to determine the effect of hatching system (house and hatcher) egg weight (heavy light) on pip-hatch time, hatchability some gosling quality traits. A total 389 eggs (fertile candling) from 2-year-old Turkish Native Goose were used in study. Before incubation process, all individually numbered weighed. Eggs divided into heavy (≥160 g) light (

In practice, many hatchability and chick quality problems have been related to the control of embryo temperature (ET) during incubation. Within an incubator, set at a constant machine temperature (MT), ET can vary substantially. Embryo temperature is the result of the balance between heat transfer to and from the embryo and heat production (HP) of the embryo. We investigated which factors theor...

The sex ratio of crocodiles is strongly biased towards females, often as high 10 females to 1 male. In crocodilians, the temperature egg incubation environmental factor determining sex. If low, around 30˚C, hatchlings are all females. Higher temperature, 34˚C, hatch males. This study was made consider asymptotic stability a positive equilibrium point in nonlinear discrete model basic nesting po...

Athens Canadian Random Bred (ACRB) chickens, a 1955 meat-type control strain, were incubated with the 2013 Cobb 500 broiler to determine differences in egg composition, conductance values, incubation duration, hatch performance, and yolk utilization. Unincubated ACRB eggs had greater percentage solids than Cobb 500 eggs. The ACRB eggs had a greater solid portion as yolk, whereas the Cobb 500 de...
