move up and to the right and hecome July 10 isoquants. Therefore, the 

 intersection of the isoquants and acceptance lines for the same date of 

 cut represents the combinations of forage and grain to produce the 

 different quantities of milk. For example, if milk output is held constant 

 at 35 pounds per cow per day, forage and grain consumption by date of 

 cut will range from 33.7 and 6.3 pounds per day to 24.9 and 9.6 pounds 

 per day, respectively. 



The following functions represent lines A, B, and C in Figures 12B 

 and 13B, i.e., these functions represent the forage and grain consumed 

 and milk produced by date of cut for the 3 grain feeding management 

 methods with undamaged forage and rain damaged forage. In these 

 functions F refers to forage, G refers to grain, T refers to date of cut, 

 and M refers to milk produced. All of the inputs and outputs are in 

 pounds per cow per day.
