Feed and Care of the Dairy Cow. 441 



When there is an ample supply of suitable roughage, a safe and 

 simple rule as to the proper supply of concentrates is that in prac- 

 tice at the Wisconsin Agricultural College, which is: Give to each 

 cow as many pounds of concentrates daily as she yields pounds of 

 butter fat weekly. Or give 1 pound of concentrates daily for each 

 3 or 4 Ibs. of milk yielded daily, according to its richness. If the 

 roughages are meager in quantity or of low palatability, more con- 

 centrates must be given than is here recommended. 



The dairyman seeking further light on the proper amount of con- 

 centrates and roughages of the various kinds for his dairy herd will 

 find the information amply and helpfully set forth in the numerous 

 feeding trials, conducted at the various experiment stations with 

 many kinds of feed, reported in Chapters XXIV and XXV. (611)
