title: Zinc concentration of liver and kidneys from rat pups nursing dams fed supplemented zinc dipicolinate or zinc acetate.
abstract: The zinc concentration of liver and kidneys was determined in rat pups nursing dams given 10 micrograms Zn/ml as either zinc dipicolinate or zinc acetate in water solution during the last week of gestation and for 5 days of lactation. Dams were fed a casein-based diet that contained 8.5 micrograms Zn/g and 2.0 micrograms pyridoxine-HCl/g during this period. The zinc concentrations of both liver and kidneys from the 5-day-old pups nursing dams fed the zinc dipicolinate solution were significantly greater than the zinc concentrations of these tissues from pups nursing dams given a solution of zinc acetate. The results demonstrate that a greater quantity of dietary zinc is transferred from the intestine of the lactating female rat to the pups when zinc is fed in the form of zinc dipicolinate.
