The Bulletin. 



The comparative results as given in this bulletin include the data from 

 November 3, 1913, to February 22, 1914, inclusive, making the total 

 ■experimental period 112 days

 for shipment to the feed lot until they were loaded and turned over to 

 the commission buyer at the local shipping station. 



LENGTH OF EXPERIMENT. 



The length of the experiment has been treated elsewhere in consider- 

 able detail. The preliminary period was 19 days, the experimental 

 period 112 days, and the period preparatory to shipment 3 days, making 

 a total feeding period of 134 days. The most important point to bring 

 out in this connection is the fact that the experimental period was not 

 of sufficient length to bring out the characteristic difference in the value 

 of the two roughage feeds used. 



Former experiments* show that for about 100 days the results ob- 

 tained from using cotton-seed hulls and corn silage in conjunction with 

 cotton-seed meal are not greatly different. It is after the expiration of 

 the one-hundred-day period or thereabouts that marked differences in 

 the value of these feeds usually occur. Even under the conditions of 

 this experiment, however, there was a marked difference in the results, 

 but more especially in the value of the finished animals. The difference 

 in the gains was not as great as would have been likely had the feeding 

 been continued for a longer period. The results under the conditions of 

 the experiment were not materially different than anticipated.
