Feeds and Feeding. 



In considering the fattening standards the student should bear 

 in mind that the most rapid fattening is usually the most econom- 

 ical, so that the standards given may often be profitably increased. 



Standards for milch cows are given for the middle of the lacta- 

 tion period with animals yielding milk of average composition. 



The standards for growing animals contemplate only a mod- 

 erate amount of exercise; if much is taken, add 15 per cent. — 

 mostly non- nitrogenous nutrients — to the ration. If no exercise 

 is taken, deduct 15 per cent, from the standard.
