were made in 1913 when the gain of 1.69 pounds was made. The 

 average for this entire period was 1.97 pounds. 



In Lot II the highest gains were made during the second year 

 by a daily average of 2.20 pounds per head. The lowest gains 

 were made during the last year by an average of 1.69 pounds. It 

 is noteworthy that this lot made its heaviest gains during the first 

 56 days, and its low gains during the second period. There was 

 very little difference in the gains made during the second period 

 in Lots III and IV. Lot V (a) and (b) and Lot VI (c) were fed only 

 one winter, and made substantial gains during the second period. 



Recapitulating the gains for the entire period of 140 days we 

 find that they are in direct proportion to the silage fed, provided 

 it was supplemented with cottonseed meal as a source of protein. 

 The lowest gain was made in Lot III which received alfalfa hay 

 as a source of protein. As may be observed there is not a very 

 marked difference in the average daily gain of the various lots, 

 which ranged from 1.79 pounds per head daily in Lot II to 2.12 

 pounds in Lot V (b), which was fed only one year.

(a) 1913-14. (b) 1914-15. (c) 1915-16. 



Table IV shows the amount of feed and air-dry matter con- 

 sumed daily per steer by periods, the amount of air-dry matter 

 required to make a pound of gain and the cost of producing a 

 pound of gain. The results are divided into two periods, namely, 

 the first 56 days and the last 84 days. The results for the total 

 period of 140 days, and the average amount of feed consumed per 

 steer per day are reported for each period. The ration in nearly
