Abstract
The max. calorigenic effect of ingestion of large amts. of oleic acid by normal cats was insignificant. In partially depancreatized cats with normal basal metabolism (BM), ingestion of oleic acid produces a far greater effect than in normal cats. If the BM of partially depancreatized cats is high, the specific dynamic effect disappears. Most partially depancreatized cats show the same rise in respiratory quotient as that following glucose ingestion in normal cats.
