BULLETIX 631, U. S. DEPARTMENT OF AGRICULTURE. 
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 com 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 dairy gain of 
1.74, 1.70, and 1.80 pounds 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 
great deal of difference between the calves of lots 2 and 3.
