256 DAIRY CATTLE AND MILK PRODUCTION 



tional pound of milk was secured for each pound of grain fed. 

 In these experiments the pastures produced an abundance of 

 nutritious grasses. It was observed, however, that the cows 

 fed grain during the summer gave better results after the graz- 

 ing period was over than those not having received grain. 

 This is also a matter of common observation, and should be 

 taken into account in considering the advisability of feeding 

 grain. The point is that the cows fed grain stored a con- 

 siderable quantity of surplus nutrients on their body, which 

 were afterwards available for the production of milk. A Jer- 

 sey cow that is giving as much as 20 pounds or 10 quarts per 

 day, or a Holstein or Shorthorn giving 25 pounds or more 

 daily, should be given some grain. The practice of the author 

 in regard to feeding on pasture is about as follows : 

 Jersey or Guernsey cow producing : 



20 Ib. milk daily 3 Ib. grain 



25 Ib. milk daily 4 Ib. grain 



30 Ib. milk daily 5i Ib. grain 



35 Ib. milk daily 7 Ib. grain 



40 Ib. milk daily 8 Ib. grain 



Holstein, Shorthorn, or Ayrshire producing : 



25 Ib. milk daily 3 Ib. grain 



30 Ib. milk daily 4 Ib. grain 



35 Ib. milk daily 5^ Ib. grain 



40 Ib. milk daily 7 Ib. grain 



50 Ib. milk daily 9 Ib. grain 



It must be kept in mind that this applies only when pastures 

 are abundant. Where a small amount of grain is fed to a cow 

 on pasture, corn is as well adapted as anything else where it is 

 cheaper than other feeds, since, on account of the comparative 

 narrow nutritive value of the grass, the corn does not unbal-
