title: Energy requirement of roosters as influenced by environmental temperature, dietary energy and age.
abstract: Little information is available on the energy requirement of roosters. The voluntary energy intake is reported for roosters exposed to environmental temperatures of 23, 30 or 37 degrees C. while fed one of three diets differing in energy level. There was a reduction in the energy intake as the environmental temperature increased. The data indicated that the energy requirement was reduced somewhat as the birds get older than 9-10 months of age.
