Effects of Dietary Magnesium and Fluoride on the Magnesium Content of Tissues from Growing Chicks

Two factorial experiments were conducted in which the effect of supplemental magnesium and fluoride on the magnesuim content of plasma (total and diffusible), bone, muscle, heart, liver and kidney were determined. Bone, liver and total and diffusible plasma magnesium were greater in birds fed diets containing high levels of both magnesium and fluoride than in birds fed diets high in either magnesium or fluoride alone. Muscle magnesium did not vary greatly with the dietary treatments and the magnesium content of the heart was remarkably constant.
