Abstract
The current study aimed to determine the metabolizable energy (ME) requirements of broiler chickens reared under free-range conditions and compared their energy use and performance with birds raised in a conventional indoor system. Ninety-six Cobb-500 male broilers were assigned to indoor or...Keywords
