4 pounds per head daily, and all of the corn silage "was given that the 

 calves would eat. This increased as the amount of hay was reduced, 

 until during the last three periods each calf ate about 25 pounds of 

 silage daily. 



The concentrated feeds of the other two lots were increased in 

 about the same manner. "When the calves of lot 2 were on full feed 

 they consumed 2 pounds of cottonseed meal and 8 pounds of shelled 

 corn per head daily, whereas each calf in lot 3 received 12 pounds of 

 shelled corn each day. The amount of silage consumed by the calves 

 of lot 2 was about 7 pounds less than that consumed by the calves of 

 lot 1. The calves of lot 3. which were fed on shelled corn alone as 

 the concentrate, consumed but about half as much silage each day 

 during the last two periods as the calves which were fed cottonseed 

 meal. The amount of alfalfa hay was the same for all of the lots. 



The last column of Table 16 shows the average amount of feed 

 consumed daily by each calf for the entire feeding period of 156 days. 



Table 17 shows the average initial weight, the average final weight, 

 the average gain per calf, and average daily gain per calf for the 

 entire feeding period.

The average weights of the calves of the three lots were very uni- 

 form at the beginning of the test, being 430. 430, and 434 pounds 

 for lots 1. 2. and 3. respectively. The average total gain per calf 

 for the entire period was 271. 265. and 280 pounds, or a daily gain of 

 1.74. 1.70, and 1.80 poimds per head, respectively. These gains were 

 very satisfactory for a long feeding period and they indicate that 

 all the calves did well. 



The calves of lot 1 were inclined to grow and did not fatten as 

 rapidly as the calves of either of the other two lots. The calves of 

 lot 3 were the fattest of the three lots, although there was not a 

 ofreat deal of difference between the calves of lots 2 and 3.
