SUMMARY— Studies of the effects of duration of physical restraint of porcine animals revealed breed influences on the responses occurring in muscles. The rate and extent of glycolysis and the color and gross morphology of the muscles of Poland China animals became more severely affected as the duration of restraint increased. The muscles of Chester White animals, however, responded to the stressor initially but, with prolonged restraint, returned to glycolytic and morphological states resembling those of unrestrained animals. The results emphasize the importance of genetic influences on stress responses and resultant muscle morphology and indicate that a specific treatment may ultimately produce opposite effects in animals that differ in susceptibility to stressors.
