It will be seen from -the above table that International Stock 

 Food is not of very great value as a food for dairy cattle. In the 

 case where a quantity of it was substituted for a like quantity of 

 the regular meal ration, the cost of producing 100 Ibs. of milk was 

 raised from 72*3 to 74 cents. 



MANGELS VS. MEAL. 



A test was made of three small groups of cows (three cows to 

 the group) which were far advanced in the lactation period, to gain 

 some information as to the possibility of replacing the meal ration, 

 or some part thereof, by mangels. 



An outline of the experiment is as follows: 



First period, February 15-21, 1910. 



Lot 1. Alma, Fannie, Gurta. 



Daily ration per cow. Meal mixture, 1 Ib. for each 3 Ibs. milk 

 produced; long straw, 3 Ibs.; sorghum ensilage, 100 Ibs.; cut straw, 

 16 Ibs. What each cow would eat up clean. 



Lot 2. Soncie, Bessie, Jessie E.
