Corn and Mixed Grains 



At the Maryland Station Patterson fed cows on corn meal as the 

 sole concentrate during the entire lactation period, while others given 

 a mixture of corn meal, gluten feed and wheat bran in such quantity 

 as to form with the roughage, chiefly dry fodder and silage corn, a 

 balanced ration. The next year the rations were reversed so that 

 each cow was on both sides of the trial. The average yearly returns 

 were as follows : 



It is shown that the returns were about 45 per cent greater when 

 feeding a balanced ration of mixed grains than with corn meal as the 

 exclusive concentrate. Only when the roughage is rich in crude 

 protein should corn constitute the sole concentrate in the ration of 

 the dairy cow, and even then more variety would be better. 



Ground Oats and Bran 



Woll of the Wisconsin Station compared ground oats with wheat 

 bran in a feeding trial with four cows lasting 47 days with the results 

 shown in the table. 



GROUND OATS COMPARED WITH WHEAT BRAN 



The table shows a return of about 11 per cent more milk and fat 

 from ground oats than from wheat bran. The high feeding value of 

 oats for the dairy cow is well illustrated in this trial. 



Kaffir Meal 



In a trial with eighteen cows for seven weeks, Cottrell and Skinner 

 of the Kansas Station found that eight pounds of Kaffir meal and twenty 

 pounds of alfalfa hay made the cheapest dairy ration for Kansas 

 conditions. When fed with prairie, timothy, or sorghum hay or corn 

 fodder, Kaffir tends to dry up the cows, and if fed abundantly to fatten 

 them.
