The function of zinc in the nutrition of man has been studied by numerous investigators in an attempt to determine the needs of the body for this element. To date no deficiency disease has been produced by a zinc-deficient diet and cured by the addition of this element to the diet.

This study was made to observe zinc metabolism of young college women on self-selected diets, to see if a requirement for zinc intake in humans could be established.

Second, the withholding of cattle from slaughter, during a cattle build-up process, rather than a scarcity of cattle in this country was primarily responsible for extremely high prices in 1951. Third, cattle production in this country has progressed in cycles of eight to ten years duration of each; the period under consideration was on the build-up side of the present cycle which began in 1949; and …
