Examining the effects of reduced incubation temperature

A new study found that lowering incubation temperature does not directly translate to lower embryo temperature in embryonated broiler-hatching eggs. Interestingly, the researchers found hatchability to improve with a lowering of incubation temperature. Studies show genetic selection over time has led to an increase in commercial broiler embryo metabolism. Because the current embryo in commercial broiler-hatching eggs has a rapid rate of growth and metabolism, it subsequently has a higher lev
