Nutritive 

 ratio 



* In rations for milking cows there should be not less than 24 pounds of dry matter. The nutritive 

 ratio should be not wider than 1:6 nor narrower than 1:4.5. About two thirds of the dry matter in the 

 ration should come from the roughage and one third from the grain, except in the case of the heaviest 

 producers, when relatively more may come from the grain (see page 1574).
