The calf meals have been mixed as needed in one hundi'ed pound lots and 

 carefully sifted to remove all lumps and foreign material. A detailed account 

 of the nature of the various substitutes and the results obtained with each, is 

 given in the following pages. A summary of the work appears on page 49 . 



Calf Meal No. 1, composed of: 



Ground rolled oats 45 lbs. 



Soluble blood flour 20 '^ 



Linseed meal 10 " 



Corn starch 14 " 



Com sugar 5 " 



Alfalfa flour 5 " 



Calcium chloride % " 



Salt 1/2 " 



Total 100 lbs. 



The chief source of protein in this meal was soluble blood flour, a high grade 

 product, readily soluble in water, specially prepared for animal feeding by 

 the United Chemical and Organic Products Company of Chicago. The rolled 

 o«ts and linseed meal were used because experience has shown that they are 

 of great value in calf feeding. The starch and sugar furnished a large part 

 of the carbohydrate of the ration, and in addition the sugar gave the meal a 

 sweet taste. Alfalfa flour was included as a desirable source of vitamines and 

 protein. Calcium chloride furnished additional calcium in a readily soluble 

 foiTU. 



Seven calves were raised on this meal, a group of four during the winter of 

 1921-22, and another group of three in 1924. The first group made an average 

 daily gain of 1.25 pounds, and required 284 pounds of drj' feed for 100 pounds 

 of gain. Strangely enough the second group did not do nearly so well, making 

 an average daily gain of 0.57 pound and requiring 494 pounds of dry feed 

 for 100 pounds of gain. Two of them (Xos. 73 and 74) made so little growth 

 and were so unthrifty that at three months of age they were changed over 

 to Meal No. 6 (see page 47 for composition of this meal) to see if it would 

 produce any more favorable results. No. 73 responded at once and made an 

 average daily gain of 1.28 pounds during the fourth month of his life, as com- 

 pared with 0.42 pound daily gain previous to the change. No. 74 did not 

 respond at all and had to be put on a skim-milk diet to save him. No reason 

 other than individual vigor of the calves can be assigned for the great differ- 

 ence in the two groups. With one possible exception all of them were strong 

 and hearty when dropped. The figures for the whole lot are: average daily 

 gain — 0.96 pound; dry feed required for 100 pounds of gain, 374 pounds. 



Calf Meal No. 2 consisted of: 



Ground rolled oats 45 lbs. 



Skim-milk powder 20 " 



Linseed meal 10 " 



Corn starch 14 " 



Corn sugar 5 " 



Alfalfa flour 5 " 



Calcium chloride ^2 " 



Salt 1/^ " 



Total 100 lbs. 



This meal was similar to Meal No. 1 except that its chief source of protein 

 was third grade skim-milk powder obtained from the Merrell-Soule Company, 

 Syracuse, New York. Four calves were raised on it and all made good growth, 

 the average daily gain being 1.19 pounds; dry feed required for 100 pounds 

 of gain — 316 pounds.
