Studies of the Grit Requirements of Certain Upland Game Birds

Abstract

Grit has been recognized as essential to most birds as an aid to the gizzard in grinding, and has been suggested as a possible source of necessary minerals. Leopold (1931) says that the peculiar correlation of pheasant success with glaciated conditions may be due to the quality or quantity of lime or grit found in these areas. Despite the recognized importance of grit, there has been little research upon its utility to game birds.
