The inner lining of the gizzard was degraded by in vitro pepsin treatment at pH values lower than 2. 2. A significant linear regression was observed between the pH values on the surface of the inner lining and those on the gizzard mucous layer just under the lining. 3. The control chicks had a specific distribution pattern of pH values on the lining of the gizzard. By feeding a gizzard erosion inducer, pH values were lowered and the distribution pattern disappeared. In the latter case, however, a gastric erosion was observed consistently at the area which showed the lowest pH value in the control chicks. 4. From the results, possible mechanisms of the formation of gizzard erosions are discussed.

在pH值低于2的条件下，通过体外胃蛋白酶处理可使砂囊的内衬降解。2. 在内衬表面的pH值与紧邻内衬的砂囊黏液层表面的pH值之间观察到显著的线性回归关系。3. 对照雏鸡砂囊内衬上的pH值具有特定的分布模式。通过投喂砂囊糜烂诱导剂，pH值降低且分布模式消失。然而，在后一种情况下，在对照雏鸡中显示最低pH值的区域始终观察到胃糜烂。4. 根据这些结果，讨论了砂囊糜烂形成的可能机制。
