was nearly as high as on the diet containing 14 per cent sardine meal, but the average live weight per bird was only 139 grams. The difference between this weight and that for the birds on Diet 11 (3% dried whey) was not statistically significant. The general rating for the diet was as high as that for Diet 11, when ground wheat replaced ground millet in the diet containing 3 per cent dried whey. Survival of birds was 5 per cent-units lower, the average live weight was about the same, and efficiency of feed utilization was higher. Using D-activated animal sterol as a source of vitamin D and yellow corn and a good grade of alfalfa leaf meal as sources of vitamin A, fish oils were omitted from the diets without causing symptons of avitaminosis. However, because of the instability of vitamin A in storage, it is advisable to include sufficient fish oil, if obtainable, in quail diets to supply at least 2,000 I. U. of vitamin A per pound of feed on a total feed basis. LITERATURE CITED
