Some Biochemical and Physical Changes Occurring in Experimentally-Inflicted Poultry Bruises.

Abstract
Proteolytic activities, detected in experimentally-inflicted poultry bruises, were influenced by many factors such as previous bruising, severity, and age of the bruise. Bruised tissues accumulated extrastromal hemoglobin which was degraded primarily to biliverdin in bruises contused on birds kept at 30[degree]C and to bilirubin in birds kept at 21[degree]C or below.
