additional pounds of grain are used, 25 pounds of milk can be produced 

 with the 6 pounds of grain and only 12.3 pounds of forage. 



To increase milk production, using only the June I isoquants, in- 

 creasing quantities of forage and grain may he fed, or 1 input may he 

 held constant and the other increased. For example, shifting from the 

 25- to the 30-pound isoquant can he accomplished hy holding forage 

 constant at 26.8 pound level and increasing grain from 3 to 5.3 

 pounds. Shifting to still higher levels of milk production can he ac- 

 complished hy increasing grain feeding and holding forage constant, 

 increasing forage with grain held constant, or hy increasing both hay 

 and grain feeding. In all instances, the acceptance level for the date of 

 cut and the minimum forage line describes the outer limits of hay and
