- 1. A fat-free diet is described in which all the components are pure compounds with the exception of casein extracted with alcohol and ether.
- 2. This diet was found to be satisfactory for use in the fat-nutritional experiments.
- 3. The rats on the milk-fat diet and on the triolein diet grew faster than those on the other diets. There was no significant difference between the milk-fat diet and the triolein diet with respect to their effect on growth.
- 4. Trilaurin, when fed at the level of 20%, enabled the rats to grow at about the same rate or slightly slower than the rats on a fat-free diet.
- 5. When 10% each of trilaurin and triolein were fed, the growth of the rats was intermediate between those receiving trilaurin and those receiving triolein.
- 6. The growth-promoting effects of the different diets could not be attributed to differences in feed consumption.
