they will be incapable of maintaining even their weight on 

 grass alone, but will actually lose in weight. This probably 

 means that the appetite and the general activity of the ani- 

 mal have been so affected by excessive fat, or by the pro- 

 longed grain feeding, that the animal will not eat enough 

 grass to even maintain its weight. It is self-evident that the 

 fat steer has a materially higher total maintenance require- 

 ment, by reason of the fact that he is much heavier, and this 

 extra weight has in no way increased his appetite or his ca- 

 pacity for grazing. In other words, his appetite and his ca- 

 pacity for grazing have at the very least stood still, while his 

 weight and, therefore, his maintenance cost have, through the 

 fattening process, been considerably increased, It is safe to 

 go even farther, and say that if the animal be made fat, i. e. 

 approximately in marketable condition, the appetite and the 

 ability to graze well will both become very materially reduced 

 at the same time that the maintenance cost per steer has been 

 increased. At this point, certainly, the steer would be inca- 

 pable of eating enough grass to maintain its weight. 



It frequently occurs that yearling cattle winter well, and 

 carrying to grass considerable fat, will weigh little if any more 

 the following fall than they did in the spring. They will be 

 considerably larger but much thinner. Fat has in this pro- 

 cess been displaced by growth. 



SECOND TRIAL OP RESIDUAL EFFECT 



The steers used in the third trial of a limited grain 

 ration, or in the winter of 1900 and 1901, were grazed 

 together the following summer. They had been fed alike 

 from the time the experiment closed, April 2Oth, to may 

 10th, on six pounds of shelled corn daily per head, as during 

 the experiment, and a mixture of the various roughages 

 used in the experiment. In the summer they had the run 

 of the same pasture, and during the last 60 days were fed 

 ear corn at pasture, all being fed together. 



They were weighed five days in succession at the end of 

 the experiment, and had been weighed 5 days in succession 

 just previous to being turned out. The following table shows 

 the gains made by each lot, and the relation that these gains 

 bear to those made in the previous winter.
