and at the same time be adapted for a still larger yield of milk, the ration 

 may be formed as follows:

This ration furnishes ample nutriment for from 35 to 45 pounds of 

 milk daily, and it can be readily adjusted to any yield, since one pound of 

 the grain mixture contains enough protein for 4 pounds of milk, but it 

 should be observed that of carbohydrates it has only enough for two pounds 

 of milk. 



It is not considered necessary to further illustrate how rations may be 

 made from the many feed stuffs that have not been used in the formulae 

 submitted, since the chief object was to show the nutrients required for 

 milk production and how to combine food stuffs so the ration will furnish 

 the cow the material she needs in milk making and not lumber up the diges- 

 tive tract with things she has no use for. 



For the convenience of feeders in determining the nutrients needed for 

 the production of a given daily yield of milk testing about 4 per cent, 

 butter fat, the following table is submitted:

THE CARE OF THE COW. 



In order to secure a large yield of milk it is quite as important that 

 the cow or herd is handled properly as that proper feeding should be
