We studied the nutritive value of fin whale oil, its hardened or polymerized oil and compared it with butter fat by rat-feeding.
The results obtained were as follows.
1) The animals appeared to be in good health and no deficiency symptoms were noticed in each groups.
2) The nutritive value of original fin whale oil was better than othar oils under our exper imental condition.
3) The nutritive values of polymerized oils decreased according the degree of polymerization, e. g. the more polymerized oil is less nutritive, but those polymerized oils were not poisonous.
4) Slightly polymerized fin whale oil showed good value than hardened fin whale oil.
