result "when the cow is fed too much, and also when she is fed too 

 little. 



WHAT BECOMES OF FEED EATEN. 



WHEN FED TOO MUCH 



Maintenance. Production. 



1000 lb. cow. 20 lbs. 4% milk. 



WHEN FED JUST ENOUGH 



1000 lb. cow. 20 lbs. 4% milk. 



WHEN FED TOO LITTLE. 



1000 lb. cow. 



10. lbs. 4% milk. 



The first section of this shows what happens when she is fed too 

 much; the middle diagram when she is fed just enough, and the 

 lower one, when she is fed too little. The animal takes care of her- 

 self first; that is natural; and when she is not fed enough to take 

 care of herself and produce milk, her production goes down. Self- 

 preservation is the first law of nature, and motherhood is often a 

 stronger motive. A cow produces milk because she expects to take 

 care of her calf and raise it. After she has fed the calf, if fed suf- 

 ficiently, she will put on fat against the time when she may need it. 

 It is the same with us. Nature provides for all animals in the 

 same way. 



Now, what can we feed the animal to provide for her, and to 

 provide for production, and in case of young, to provide for them? 

 First, something succulent. We know that when we put that cow out 

 on grass, she will increase in production if she is a milk animal, or 

 in fat, if she is a flesh animal. Then in winter we can feed silage, 

 from twenty-five to forty-five pounds, carrots, turnips, rutabagas and 

 beets. Silage can be raised cheaply. Roots are rather expensive. 

 Potatoes affect the butter fat, and other things have various other 

 effects. Dried beet pulp is good. They can be moistened, so as to 

 be palatable to the animal and make a fair substitute for a succulent 

 feed.
