476 DISEASES OF CATTLE. 



clover hay and 2 or 3 pounds of bran or oats. Where it is desirable to 

 raise a large amount of roughage, the farm furnishing only the bulky 

 feed, let the corn for silage be of some large variety, which will barely 

 mature in the given locality, planted on very rich land, so thick that 

 very few ears will form. The amount of coarse feed furnished per 

 acre is enormous, but it must be backed up by a full grain ration. 

 Some farmers put silage into the pit without cutting, but a good feed- 

 cutter elevates it so economically, and cut silage packs so well and is 

 so much more easily removed at feeding time, that cutting the corn 

 should generally be practiced. 



FOOD REQUIRED TO PRODUCE 100 POUNDS OF MILK. 



The dairyman should so study the operations of his farm that he 

 knows what it costs to produce a hundred pounds of milk or butter. 

 The calculation is a complex one, but it is possible, and has been done 

 by a good many farmers, who have found much interest and profit in 

 the work. In order to give some idea of the amount of food required 

 to produce a hundred pounds of milk, I have prepared a table giving 

 the results of observations at experiment stations in four States and 

 Canada.
