Feeding Value of beta-Carotene following Treatment with N2O41

R. J. Emerick and Virginia F. Lievan2

Station Biochemistry Department, South Dakota Agricultural Experiment Station, Brookings, South Dakota

To further clarify the relationship between feeds of high nitrate content and the vitamin A status of animals, ß-carotene treated with N2O4 was fed under various dietary conditions to albino rats to determine whether this material retained any vitamin A activity or was toxic. Weight gains and liver vitamin A storage indicate that the material was neither toxic nor had any vitamin A activity.
