By the third week, six calves developed an appetite for this material 

 and not until the seventh week, were all the calves in-Lot I eating this 

 feed. The amount of this mixture consumed by the calves in Lot I 

 averaged .98 pound per day. The total amount consumed per head for 

 the period included in this experiment was 178.71 pounds, equivalent 

 to 1.59 bushels of corn and 2.78 bushels of oats. The variation in 

 daily consumption between individual calves was slight, the mini- 

 mum being .76 pound and the maximum, 1.07 pounds. No re- 

 lationship appears to exist between the amounts of dry mash con- 

 sumed and the gain in live weight. 



The only dry roughage fed was alfalfa hay and the average 

 daily amount consumed by Lot I was 2.5 pounds, equivalent to 455 

 pounds per head for the period included in this experiment. Some 

 alfalfa hay was consumed during the first week. During the sev- 

 enth and eighth weeks, the largest increase in daily consumption of 

 alfalfa hay took place. By the twelfth week the calves were consum- 

 ing approximately, two pounds per head per day ; the fifteenth week, 

 three pounds "per head per day; the twentieth week, four pounds 

 per head per day ; and the twenty-fourth week, five pounds per head 

 per day. The maximum daily consumption of alfalfa hay by Lot 

 I was 5.59 pounds. The appetite for alfalfa hay varied with indi- 

 viduals as is shown by the following: one calf began eating hay 

 4uring the first week, three during the second week, four during the 

 third week, six during the fourth week, seven during the fifth week, 

 nine during the sixth week and ten during the seventh week. 

 Calf No. ii consumed the smallest amount of alfalfa hay or 

 .66 pound less than that eaten by the average calf in Lot I. This 

 calf weighed the least at birth and consumed approximately, the 

 smallest amount of all feeds fed. The gain in live weight is directly 

 proportional to the feeds consumed so far as this individual calf is 

 concerned. The calf that ate the largest amount of hay con- 

 sumed .'6 pound more hay than the average for the lot and ranks 

 high from the standpoint of total gain. 



The silage was not relished to any great extent by the calves 

 in this lot, although they were not given an unlimited amount as is 

 sometimes done. The first indication of a desire for silage was 

 manifested during the fourth week, although a very small amount was 

 consumed. One-fourth of a pound per day was consumed during 

 the ninth week, half a pound during 1 the nineteenth week and .63 

 pound during the twenty-sixth week. Two calves began eating 

 silage by the fifth week, five during the seventh week, seven during 

 the eighth week, eight during the ninth week and ten during the 

 tenth week. 



The average daily consumption of silage was .33 pound per 

 head or approximately, 60 pounds per head for a period of one 

 hundred eighty-two days. The variation in the amount of this feed
