Relationship of heat tolerance and oxygen consumption in chickens
Poultry Science
|January 1, 1975
Abstract:
Chicks from lines genetically selected for high or low heat tolerance were compared to lines selected for high or low oxygen consumption. Oxygen consumption, survival time, respiration rate, lung capacity and body weight were determined. Selection for high oxygen consumption ahd high heat tolerance resulted in birds with similar characteristics. The high line birds for both heat tolerance and oxygen consumption had greater oxygen consumption, survival time and lung capacity but lower body weight.
