Greater metabolic heat production; the heat is on!

Greater metabolic heat production, the heat is on!

Modern, fast-growing broiler chickens have been genetically selected for a rapid growth rate and improved muscle tissue deposition, which leads to greater metabolic heat production. This, in turn, makes them more susceptible to high temperatures and humidity when compared to older, native breeds. Besides their high metabolic heat production, broilers also have abundant feathers and…

Maintaining gut health: Healthy from the inside out
