Interrelationships between Magnesium and Fluoride in Chicks

Abstract
Two factorial experiments were conducted with chicks to investigate a possible interrelationship between high levels of dietary fluoride and magnesium. The first experiment consisted of two levels of supplemental fluoride (none and 0.08%) and two levels of supplemental magnesium (none and 0.25%). The second experiment included the same levels of fluoride and magnesium duplicated on two levels of dietary phosphorus (0.7 and 1.0%). The following observations were made:
