Studies on fat digestibility in experimental animals and some factors affecting its estimation.
Using white rats, a feeding trial in which levels of fat and of mineral (bone char) supplement were varied showed apparent digestion coefficients of better than 92% for bydrogenated peanut oil or m.p. 42°C. At a ten percent level in diets, this fat was more digestible than at 20%. Ether-extraction g...

| Summary: | Using white rats, a feeding trial in which levels of fat and of mineral (bone char) supplement were varied showed apparent digestion coefficients of better than 92% for bydrogenated peanut oil or m.p. 42°C. At a ten percent level in diets, this fat was more digestible than at 20%. Ether-extraction gave higher coefficients on the average than did titrimetric estimation of total fatty acids. This discrepancy was clearly due to the failure of diethyl ether to measure soaps by conventional extraction procedures, and such soaps were shown present in feces to an extent dependent on the levels on fat and of calcium in the diets. |
