Abstract

Strain gage transducers were permanently implanted on the muscular stomachs of 13 turkeys, 3 great-horned owls and 2 red-tailed hawks to monitor gastric motility before, during and after eating. Following fasting, the sight of food resulted in significant increases in gastric contractile activity in all three species. Gastric motility further increased when the birds were allowed to eat. In raptors, however, a brief interruption in gastric motility occurred immediately after eating. This is apparently analogous to receptive relaxation which occurs in the stomach of mammals.

摘要

应变片传感器被永久植入13只火鸡、3只大角鸮和2只红尾鹰的肌胃中，以监测进食前、进食期间和进食后的胃动力。禁食后，看到食物会导致这三个物种的胃收缩活动显著增加。当鸟类开始进食时，胃动力进一步增强。然而，在猛禽中，进食后胃动力会立即出现短暂中断。这显然类似于哺乳动物胃中发生的容受性舒张。
