The cost of the above mixtures naturally will vary in propor- 

 tion to the cost of the several by-products of which they are com- 

 posed. If desired, linseed meal can be used in place of cottonseed 

 meal, or hominy in place of corn meal. 



The quantity of grain to be fed daily naturally 

 Quantity of depends upon the size of the cow, the ({uantity of 

 Grain Daily, the daily milk yield, and the local market value of 

 the milk. The richer the milk, the more food re- 

 quired to produce a given quantity and vice versa. Seven pounds 

 daily is a fair average amount for cows weighing 800-900 pounds, 

 which produce ten quarts of 5 per cent milk. Grain prices con- 

 tinue high and feeders in localities where there is not a quick 

 demand for milk may find it economy to use only 5 pounds of 

 grain daily and a maximum amount of home grown coarse feeds.* 

 Heavy milking cows weighing 1,200 pounds may require 12 or 

 more pounds of grain daily, depending upon their ability to utilize 

 it. It is not good economy to unduly force the cow, especially i£ 

 it is desired to keep her in the herd from year to year. 



The usual daily roughage ration to go with the above grain 

 mixtures will consist of what hay the animal will eat clean (18-24 

 lbs.) or one bushel of corn silage and 10-16 lbs. of hay. 



* Early cut hay, hay of peas and oats cut when in blossom, clover hay, rowen and well-eared corn 

 silage all aid in reducing the grain bill.
