that all ten-year-old boys need four pieces of bread and meat for 

 supper. Their needs are different because the boys are different ; 

 not only in appetite but also in the ability to digest food. I cannot 

 tell you just how much food your milch cow needs because I do not 

 know the cow. What I can do, however, is to tell you the amount 

 of food which has given the best results for many other milch cows, 

 and which will probably be somewhere near what your cows need. 

 These feeding standards are not rules^ hut hints. The skill of the 

 feeder may he measured hy his ahility to find outhoio far the needs 

 of each animal %oill warrant a variation from the standard when 

 feeding that animal. You would not give a snap for a hired man 

 who does everything by rule of thumb. I want you to come to this 

 table for suggestions, not for directions. Do not follow it pound for 

 pound, but vary the amount with each animal according to its appe- 

 tite and ability to use food. 



The above teaching shows what is likely to take place. Every 

 animal is a law unto itself. The farmer must experiment with his 

 animals. The above remarks will set you to thinking on the sub- 

 ject, and that is the most that we can hope to do.
