SUMMARY 



It will be profitable to consider together the results of 

 the four years' experiments with roughnesses of various 

 kinds when fed without grain. Altogether fourteen lots of 

 animals were involved, the experiments extended over four 

 years, and included: 



Four trials of Whole Corn Stover versus Timothy Hay. 



Two trials of Shredded Stover versus Whole Stover. 



Two trials of Siloed Corn Stover versus Whole and 

 Shredded Stover. 



Two trials of equal parts Corn Stover and Clover Hay 

 versus Timothy Hay. 



I. The Feeding Value of Timothy Hay Without 



Grain 



On the basis of the results reported in the preceding 

 tables it may be said that yearling steers when in thin con- 

 dition and after having lost what the farmer terms "grass 

 sap," which in practice usually occurs before the animals 

 leave the pasture, may be wintered on timothy hay without 

 any grain whatever and make a small gain in live weight. 

 That is, timothy hay of average quality is nutritious enough 

 to a little more than maintain animals of this class and in 

 this condition. 



The gain made, however, is small, varying from a slight 

 loss in one experiment, when the winter was particularly un- 

 favorable, to a considerable* gain when the quality of the 

 hay was good, and the winter was dry, bright and crisp but 

 moderate. 



The whole gain for the four years was 85 pounds for one 

 steer in 281 days, or the equivalent of a gain of 54 pounds 

 per steer for a six months wintering period, from November 

 ist to April 30th. It is believed that this is as high as 

 would occur in actual practice. 



To accomplish this, yearling steers weighing an average 

 of 750 pounds will, on the basis of our four years' experi- 

 ments, consume and waste an. average of 18.25 pounds of 

 hay per day. This is the actual average amount offered in 

 our experiments covering four years, when computed on the
