The murine mutation, lethal milk, results in production of zinc-deficient milk.

Abstract excerpt

Normal or mutant pups that nurse dams homozygous for the lethal milk (lm) mutation die as a result of zinc deficiency. Previous determinations of the zinc concentration of the mutant milk have been conflicting. This work demonstrates that the amount of 65Zn recovered in the organs of pups following in intraperitoneal injection of 65Zn to lactating dams was reduced 50-60% in the stomach, 25-30% in the gut and...
