Abstract
Blood urea content of rabbits remarkably decreased within 24 hours when more than 250g of sweet potatoes were fed. At the same time, urea and total N content in urine also considerably decreased.
No significant changes, however, were observed when potatoes were fed. Various experiments were made considering the balance of sugars and protein in substances of sweet potatoes and potatoes. Besides the differences of nutritive balance, some factors which inhibit urea formation are supposed to exist in sweet potatoes.
