Effects of Food and Exercise. 



No better summary 

 of the effects of food 

 and exercise in animal 

 nutrition could be giv- 

 en than the following, 

 by Dr. E. L. Sturte- 

 vant, of Massachusetts: 



"1. That the production 

 of butter is largely depend- 

 ent, on the breed. 



"2. That there is a 

 structural limit to the pro- 

 duction of butter in each 



"3. That when the cow 

 is fed to this limit, increased 

 food cannot increase the 

 x product. 



"4. That the superior 

 cow has this structural limit 

 at a greater distance from 

 ordinary feed, and is more 

 ready to respond to stimuli 

 than the inferior cow. 



" 5. That, consequently, 

 the superior cow is seldom 

 fed to her limit, while the 

 inferior cow may be easily 

 fed beyond her limit; and, 

 as a practical conclusion, 

 increased feed with a supe- 

 rior lot of cows will increase 

 the butter product ; but if 

 fed to an inferior lot of 

 cows, waste can only bevthe 

 result. 



"6. That the character 

 of the food has some influ- 

 ence on the character of the 

 , butter ; but even here, breed 

 influences more than food.
