Each calf in lot 1 ate an average of 2.61 pounds of cottonseed meal, 
10.26 pounds of cottonseed hulls, and 4.31 pounds of hay during the 
whole fattening period of 107 days. It should be understood, how- 
ever : that these calves were not started off suddenly with these 
amounts of feeds ; they gradually were made accustomed to the feeds, 
especially cottonseed meal, by beginning with small amounts. For 
instance, on November 17, the day the test was begun, each calf in 
this lot was given only 1.5 pounds of cottonseed meal, and this 
amount was divided equally between two feeds; on this same day 
each calf ate 7 pounds of cottonseed hulls and 4 pounds of hay. On 
December 2, or 15 days after the test began, the daily feed of each 
calf in the test had been raised to 2 pounds of cottonseed meal, 9 
pounds of cottonseed hulls, and 4 pounds of hay. By January 13 
the daily feed for each calf had been raised to 3 pounds of cottonseed 
meal, 11 pounds of cottonseed hulls, and a fraction over 4 pounds of 
hay. The daily allowance of cottonseed meal was not increased after 
this date. 
The calves in lots 2 and 3 were fed somewhat more liberally on the 
concentrated part of the rations and more sparingly on the rough- 
age parts. This could be done because of the introduction of corn- 
and-cob meal. Changes in either the amount or the kind of feed 
should be made gradually, especially when dealing with young 
animals. 
WEIGHTS AND GAINS. 
When the first weights were secured, in November, the calves 
averaged from 6 to 8 months hi age. On this date they averaged 376 
pounds in weight. Though not large for their age, they were consid- 
erably larger than the average for this State. Their dams were large 
for Alabama cows, probably averaging 1.000 pounds in weight in 
normal breeding condition, and they should have produced larger 
calves. In Department Bulletin 73 it is seen that calves averaging 
460 pounds at 9J months of age were gotten from cows which aver- 
aged only 630 pounds in weight in their winter form, or about 850
