This meal combined the chief protein sources of Meals 1 and 2; also the 

 starch and alfalfa flour were increased five pounds each, the rolled oats being 

 reduced ten pounds. This change was made for two reasons, (1) it was thought 

 that the alfalfa flour constituted an excellent source of vegetable protein, of 

 vitamines, and of ash, and (2) for the sake of economy. At the time the meal 

 was formulated rolled oats was selling for four cents a pound while starch 

 was less than two cents a pound and alfalfa flour was two and a half cents. 



Four calves were raised on this meal; two others did not thrive on it at all 

 and it was deemed best to dispose of them. Of the four raised, two did rea- 

 sonably well and the other two made very poor growth. The average daily 

 gain was 0.77 pound and the dry feed required for 100 pounds of gain was 

 349 pounds. It is evident that this meal was not suitable as a skim-milk sub- 

 stitute. Thinking that the trouble might have been due to the increase in 

 amount of alfalfa flour, this ingredient was cut down to five pounds, the 

 amount used in Meals 1 and 2, and the rolled oats increased to forty pounds. 

 The corn si;gar was discontinued and five more pounds of corn starch sub- 

 stituted for it. The meal, which was designated as Calf Meal No. 3 (modified), 

 then consisted of: 



Ground rolled oats 40 lbs. 



Soluble blood flour 5 "

Three calves were raised on this modification of Meal No. 3. They made 

 slightly better growth than did those on the original meal, but required con- 

 siderably more food for an equal amount of gain. The average daily gain 

 was 0.89 pound, and the dry feed required for 100 pounds of gain was 381 

 pounds.
