Table II shows the average daily rations that were supplied during 

 the feeding period. On account of several changes that were made dur- 

 ing the progress of the experiment, it became necessary to present the 

 data embodied in this table in four irregular periods, in order that 

 proper comparison might be made. 



Fig. 3 Contentment reigns in the feed lot. 



The tabulation in the first period shows the average daily ration con- 

 sumed by Lots 1 and 2 during the fifty-nine-day period. It also shows 

 that the average daily gain per lamb in these lots during the fifty-nine- 

 day period was 0.349 and 0.285 pound, respectively. Although the 

 fact is not shown in the table, it may be of interest to mention that 

 during the first thirty-eight days the lambs were on feed, Lot 1 made 

 an average daily gain of 0.39 pound per head, while those in Lot 2 

 gained 0.316 pound daily. During the three weeks immediately fol- 

 lowing the first thirty-eight days of the experiment the daily gains 

 dropped off materially. In Lot 2 the average daily gain dropped to 

 0.23 pound during the last three days of the first period. 



At this point in the experiment it was evident that it would not be 

 well to allow the lambs constituting Lot 2 to remain on the sole ration 

 of cotton seed meal and silage for a longer time, as it was with diffi- 

 culty that they were kept "on feed." In an effort to overcome this
