Behavior-genetic analyses and poultry husbandry


, : Behavior-genetic analyses and poultry husbandry. Poultry Science 72(1): 1-6

Domestication, one of the great innovations in human history, has had a profound effect on agriculture and the development of urban societies. Domestication is a continuing genetic process through which anatomy, behavior, and physiology are modified to suit specific needs. In poultry, the process has accelerated during the past several decades because of increased selection pressure and development of specialized male and female lines in breeding programs. Large changes have also occurred in the intensification of environments in which poultry are maintained. Such intensification is a function of escalation of land, energy, and labor costs. Whether the rate of change of these nongenetic factors is faster than biological change is an important issue in the consideration of behavior-genetic analyses and poultry husbandry. Complex behavioral, genetic, and physiological responses are involved in the buffering necessary for animals to cope with changes in their physical and social environments. Knowledge of behavioral range and genetic variation of short- and long-term responses is essential to understanding how poultry adapt. Although innate behaviors and habituation can prevent some stimuli from causing manifestations that detract from well-being, husbandry conditions should optimize behavioral responses with biological advantages to individuals and populations.
