128 DAIRY FARMING 



Holstein, Shorthorn, or Ayrshire, producing : 



25 pounds milk daily 2 pounds grain daily 



30 pounds milk daily 3 pounds grain daily 



35 pounds milk daily 5 pounds grain daily 



40 pounds milk daily 7 pounds grain daily 



It must be kept in mind that this applies only when pas- 

 tures are abundant. When a small amount of grain is fed 

 as a supplement to pasture, little attention is necessary as 

 to the relative amount of protein and carbohydrates that 

 it contains. When corn is the cheapest grain, it may be fed 

 alone if desired. Any mixture of common concentrates 

 serves the purpose, since it is total digestible nutrients that is 

 needed and the protein is usually supplied in ample amounts 

 by the grass. When larger amounts of grain are fed, more 

 care must be taken to have enough protein. 



119. Providing for Periods of Short Pasture. Unfortu- 

 nately the season of abundant pastures is often short. In 

 many localities a dry period of several weeks often occurs 

 at times during the summer season. It is probable that as 

 much loss occurs from improper feeding at such times as 

 is caused by improper feeding during the winter. As long 

 as the cows are on pasture, and other work is pressing, the 

 farmer is inclined to let the cows get along the best they can. 



It is well known to all experienced dairymen that if a 

 cow is once allowed to decline in her milk production, it is 

 difficult to bring her back to normal. To make a large 

 profit from the cow, a large yearly production must be had 

 and to obtain this ordinarily requires that the flow of milk 

 be kept up for 10 months out of the year. It is possible to 

 supplement short pasture by the feeding of grain, but this is 

 as a rule unnecessarily expensive. It will pay, however, if 

 no other feed is available. Provision for short pasture is
