Figure 12B is an enlargement of the outlined rectangular section of 

 Figure 12A. This is the section of the isoquants and acceptance lines 

 used to determine the functions that represent the 3 management meth- 

 ods of feeding grain in the production of milk, i.e., grain constant, milk 

 constant, and constant in milk-grain ratio. The X and Y axes, forage ac- 

 ceptance lines, and isoquants in Figure 12B are represented in the same 

 manner as in Figure 12A, while lines A, B, and C are the functions that 

 represent the management methods of feeding grain, grain constant, 

 milk constant, and milk-grain ratio, respectively. Implied in this Figure 

 12B, as in Figure 12 A, is that forage acceptance line June 1 moves down 

 and becomes forage acceptance line July 10, and the Jime 1 isoquants
