Calculated values for superhay when used as a supplement in winter 

 feeding of weaner calves are shown in table 15. These values are based on 

 the feeding of slightly more than 1 pound of superhay with approximately 11 

 pounds of the basic hay per day per animal. If it were feasible to feed 

 smaller amounts of the supplement hay, that is, less than 1 pound per day, 

 when the crude protein content of the basic hay is higher than 8 percent, the 

 value of superhay would be somewhat higher. The difficulty of feeding less 

 than 1 pound of supplemental hay per day is not insurmountable, but this 

 rate of feeding is impractical. Therefore, these values are based on the 

 lowest practical amount of supplemental hay that can be fed. 



It is well to remember also that the real value, or the value through use, 

 of cottonseed cake decreases as the crude protein content of the basic hay
