Research investigates cyanosis in male broiler chickens

Underlying cause of cyanosis may be a cardiac problem affecting blood flow in male breeders, research reveals

USPOULTRY and the USPOULTRY Foundation announce the completion of a funded research project at Mississippi State University in Pearl, Miss., investigating the cause of cyanosis in male breeder broilers. The project is part of USPOULTRY's comprehensive research program encompassing all phases of poultry and egg production and processing.

The research project, led by Dr. Danny Magee, investigated the cause of cyanosis in male broiler breeders. Cyanosis is a dark blue or purple coloration of the skin, comb, and wattles, and has been seen in the industry for several years. The research found that the underlying cause may be a cardiac problem affecting blood flow in the male breeders. The project investigated the contributions of feeding programs on the incidence of the condition.

Other Mississippi State University researchers involved with the project were Kelli Jones, Floyd Wilson, Erica Varavik-Munsell, Timothy Cummings and Robert Wills.
