 DISCUSSION OF RESULTS. 



Tables I and 2 give the result of this feeding test. The time 

 of feeding is divided into periods, to better study the results, as the 

 experiment progressed. Each lot of steers received the same kind 

 and juality of hay throughout the test. The only difference in the 

 ration given was in the varying amounts of grain. 



GAIN IN LIVE WEIGHT. j 



Table No. i shows the weights and gains made by the various 

 lots. Considering, first, the experiment period of 99 days, or 14 

 weeks, from Dec. 20 to March 29, we find that lot II (5 pounds of 

 .grain per day) gained 536 pounds, while lot IV (10 pounds of grain 

 per day) gained 706 pounds, or 170 pounds more. This was also 

 36 pounds more than was gained by lot I and 51 pounds more than 

 was gained by lot III. The daily gains were low, compared with 

 previous years' feeding. Lot I gained more than lot II, although 

 lot I received less grain. Lot IV, on 10 pounds of grain, gained 

 but 1.19 pounds per day per steer, and lot I, on three pounds of 

 grain, gained 1.13 pounds per day per steer a very slight differ- 

 ence. 



Considering the experiment period the effect of the increased 

 grain ration is seen in the increase in the gains made as the amount 

 of grain is increased, but the difference is much less than the dif- 

 ference in the grain ration would lead a person to expect. 

 Considering, next, the whole time of the test we have a somewhat 

 similar result. The steers in each lot gained on the average from 

 149 pounds for lot II to 177 pounds for lot IV and averaged for the 

 carload 167.7 Mbs. each during the 129 days of the test. The daily 

 gain per steer ranged from 1.16 pounds per day for lot II to 1.37 

 pounds for lot IV. When we consider the whole of the feeding 

 period, except for lot II, there is but little difference in the gains 

 made by the different lots fed the different amounts of grain. Lot 

 I received 3 pounds of grain per day per steer and gained 1024 

 pounds. Lot III received 7 pounds per day and gained 1037 

 pounds, or but 13 pounds more than lot I in 129 days Lot IV re- 

 ceived 10 pounds of grain per day and gained 1066 pounds, or but 

 44 pounds more than lot I on three pounds of grain per day. 



Considering each individual steer, those fed on 7 and 10
