The principal difference between this meal and the preceding ones is in the 

 source of the carbohydrates. In an attempt to more closely resemble milk, 

 milk sugar was substituted for all of the starch and part of the rolled oats. 

 Also ten pounds each of coconut and peanut meal were included to give a 

 higher fat content and in the case of coconut meal to supply more of Vita- 

 mines "A" and "D." 



Four calves were raised on this meal and, taking into consideration the fact 

 that three of them were delicate to begin with, they made very fair growth, 

 the average daily gain being 0.99 pound, and the dry feed required for 100 

 pounds of gain being 303 pounds. At prevailing prices of milk sugar this 

 meal was too expensive, but it indicated possibilities which should not be dis- 

 regarded. 



Calf Meal No. 5: 



This meal was not prepared to feed as a gruel, but as a dry grain for the 

 control lot of calves which received skim milk, and was not consumed in any 

 quantity until they were 5 to 6 weeks old. It was also fed as dry grain for 

 two lots of calves that received modified skim milk as the liquid portion of 

 their diet. It was composed of: 



Ground whole oats (not rolled) 30 lbs. 



Flour middlings 20 " 



Com meal 191/2 " 



Linseed meal 10 " 



Coconut meal 10 " 



Peanut meal 10 " 



Salt 1/2 " 



Total 100 lbs. 



Results secured in feeding this meal will be discussed under the heading of 

 skim milk and modifications of skim milk. 



Calf Meal No. 6: 



This meal was formulated as a result of our experience with the other meals 

 over a period of two years. It consisted of: 



Ground rolled oats 20 lbs. 



Soluble blood flour 10 '| 



Skim-milk powder 10 



Corn starch 19 



Red dog flour 15 " 



Linseed meal 10 " 



Coconut meal 10 " 



Alfalfa flour p ^^ 



Calcium chloride "2 



Salt V2 " 



Total 100 lbs. 



It is in many respects similar to Nos. 1, 2 and 3. Red Dog flour was sub- 

 stituted for a portion of the rolled oats for considerations of economy and 

 to make a little more variety. Coconut meal was included for the same reason 

 as in Meal No. 4. Peanut meal was not included because of difficulty in ob- 

 taining it. 



Six calves were raised on this meal. None of them made very good growth 

 at first. Later four of them did very well, but two of them (67 and 68) con- 

 tinued to do so poorly and refused so much of their feed that it was decided 

 to remove from the meal for these two, the coconut meal, which it was thought 

 might be the particular ingredient they objected to. After this change they 

 made somewhat better growth. The average daily gain for all sis was 1.02
