USING FEEDS FOR BEST RESULTS 3! 



his animals partake of almost any kind of food, but 

 nothing he can do will induce these same animals 

 to eat a disagreeable or unappetizing food heartily 

 enough to get a response much beyond their main- 

 tenance needs. Growth and production are invaria- 

 bly associated with well-flavored and appetizing 

 food, even though they add nothing to the energy 

 or nutritive value of the food. 



Digestibility Little Influenced by Quantity. 

 Ordinarily digestion is but slightly influenced by 

 big appetites. Heavy eaters are usually the most 

 profitable animals. Fed to their full capacity they 

 give as good an account of their food as when lim- 

 ited to half feeds. Food is digested and assimilated 

 just as completely in full as in half-filled stomachs. 

 The most rapid growth, or the largest milk flow, is 

 to be had when the animal is permitted to eat to its 

 full capacity ; and this is another reason why the ration 

 must be palatable and attractive to taste and smell. 



The Individual Character of the Animal undoubt- 

 edly affects the proportion digested. Armsby has 

 found that a pure-bred animal of superior breeding 

 renders a better account of its food than a scrub. 

 Of two animals supplied with the same feed, one 

 will often persistently digest a larger proportion 

 than the other. Often very greedy eaters show very 

 poor fattening qualities. 



In young animals the digestive power is appar- 

 ently equal to animals of mature age. 



Digestibility Decreases as Plants Mature. All 

 classes of plants show a striking diminution in
