74 THE CREAMERY PATRON'S HANDBOOK. 



corn, contain a very high per. cent, of protein, and that both contain a high 

 per cent, of digestible matter. If we add 2 pounds of corn and 6 pounds 

 of gluten feed we find that the ration will contain more protein and less 

 carbohydrates than is needed for a daily yield of 25 pounds of milk; and 

 if 3 pounds of corn and 5 of gluten feed are fed there will be a shortage in 

 protein and an excess of carbohydrates. So the proper balance is between 

 these two. We conclude, therefore, to try 2.5 of corn and 5.5 of gluten 

 meal. Now this presents a new phase of our work, and we therefore go 

 into the details in making the calculations. One pound of corn meal 

 contains .079 of protein, .667 of carbohydrates and .043 of fat, and multi- 

 plying these several numbers by 2.5 we get as a product .1975 of protein, 

 1.667 of carbohydrates and .1075 of fat. In one pound of gluten feed there 

 are of protein .233, of carbohydrates .507, and of fat .027, and multi- 

 plying these numbers by 5.5 we get as a product 1.2815 protein, 2.788 of 

 carbohydrates and .1488 of fat. By adding the two products to the nu- 

 trients in the timothy and stover we have the following ration:

While the ration is a trifle short in carbohydrates for a daily yield 

 of 25 pounds of milk, this can easily be made good by bedding with bright 

 straw. Even well fed cows will eat some of the litter, especially if they can 

 reach over into an adjoining stall for it. 



With prairie hay, marsh hay and the corn plant as roughage, it is neces- 

 sary to make up the concentrates from half to two-thirds of such mill pro- 

 ducts as gluten feed, oil meal, gluten meal and cotton seed meal, if a large 

 flow of milk is to be maintained. For a medium flow, bran, shorts, mid- 

 dlings, dry brewers' grains, oat feed and cotton seed will answer. Farmers, 

 as a rule, do not take kindly to buying mill feed, and prefer to feed such 

 hay as timothy, prairie or marsh with corn and oats, or corn and bran for 

 the concentrates. Let us see what these feeds will provide for. An average 

 cow can take about 18 pounds of hay and 8 pounds of grain.

This ration will be good for about ten pounds of milk. This method 

 of feeding largely accounts for the fact that the average cow yields only 

 from 125 to 150 pounds of butter a year. There is much said about farmers
