Abstract
Summary
This study has demonstrated that the guinea pig does require zinc. The animals fed a zinc deficient diet (1.2 ± 0.4 ppm) had a significant (p < 0.001) decrease in the plasma and femur zinc concentration compared with those guinea pigs fed a diet containing 104 ± 8.4 ppm zinc. The quantitative requirement of zinc for the guinea pig has not been determined in this study. A possible use of the guinea pig in a study to investigate the relationship between zinc and ascorbic acid is discussed.
