GRAIN MIXTURES FOR DAIRY COWS. 



233 



The following rule for feeding good dairy cows ig a safe one to 

 be guided by: Peed as much roughage (succulent feeds like silage 

 or roots, and hay) as the cows will eat up clean, an^ in addition, 

 1 pounds of grain-feed (concentrates) a day per head for every 

 pound of butter fat they produce in a week (or one-third to one- 

 fourth as many pounds as they give milk daily). 



s 



The farmer should aim to grow protein foods like clover, 

 alfalfa, peas, etc., to as large extent as practicable, and thus reduce 

 his feed bills.
