The dairy cow has been likened unto a factory a 

 factory for the production of milk and butter. She 

 eats her feed, converts it into blood and from the blood 

 which passes through the mammary gland or udder, 

 she extracts the milk. The output of this factory, like 

 that of any other factory, depends much upon the 

 amount and quality of raw material consumed. No 

 cow can produce a large quantity of milk and butter 

 unless she has the capacity and consumes a large quan- 

 tity of good feed. Since it is impossible to feed fat 

 into milk or change the .average per cent of butter fat 

 in a cow's milk by the kind, amount or quality of feed, 

 the thing for us to do is to feed her in such a way as 

 to enable her to produce the maximum amount of milk. 

 From more milk we can get more butter fat. 



In order to get a cow to consume large quantities 

 of feed, the feed must be good and palatable. Pala- 

 tableness means much. Every feeder of live stock of 

 any kind recognizes the importance of keeping the ap- 

 petites of animals good. 



During the process of fermentation of silage in the 

 silo, the corn plant is rendered more digestible and 

 more palatable than dry shock corn, and a flavor very 

 acceptable to dairy cows is produced. After cows have 

 been fed silage, they will stretch out their backs and 

 turn their heads in the direction of the feeder the min- 

 ute he starts toward them with a box of silage. So 

 well do eows relish silage, they will eat more of it 

 than they do of dry fodder or even of green corn. This 

 is a point in favor of silage, because every cow must 

 eat so much feed for the daily maintenance of her 

 body. After this maintenance requirement is met, all
