Abstract
The fleshes tested as sources of the B-vitamins for the growth of young rats are listed in the order of decreasing value: pork, beef, white spring salmon, halibut, lemon sole, and lingcod. Pork flesh permitted a maximal rate of growth. The principal vitamin deficiencies found in the other fleshes are indicated in decreasing order of magnitude: beef—thiamine, riboflavin; white spring salmon—riboflavin, thiamine; halibut—riboflavin and pantothenic acid, thiamine; lemon sole and lingcod—thiamine, riboflavin, pantothenic acid.
