CALF FEEDING IN ALABAMA AND MISSISSIPPI. 53 
The roughage used during one year was not the same as that used 
another year, but each year the roughage was exactly the same for 
the lots which were being compared. 
In the first two tests, where corn was substituted for cottonseed 
meal, the substitution was made pound for pound and the results 
were unsatisfactory, because a pound of corn has a much smaller 
feeding value than a pound of cottonseed meal; and the corn- fed 
calves therefore were getting a smaller amount of digestible nutrients 
and consequently did not do as well as the cottonseed-meal-fed calves. 
During the later experiments, where corn was substituted for cotton- 
seed meal, the substitution was made in about the proportion of 2 
pounds of corn for 1 pound of cottonseed meal. 
The use of corn invariably increased the cost of the gains made, 
regardless of the kind and amount of roughage used. Where corn 
was fed very sparingly as a substitute for cottonseed meal, the 
amount or size of the daily gains of the calves was not increased ; but 
where corn was fed liberally the calves made larger daily gains than 
the calves fed on cottonseed meal alone. The increased gains were 
not great enough, however, to overbalance or offset the increased cost 
of the gains, so the cottonseed-meal-fed calves were usually a little 
more profitable. 
Unless the calves that were fed corn were followed by shoats to 
utilize the waste grain, the feeding of corn was not as profitable as 
the use of cottonseed meal as the sole concentrate. 
In the South, during the last three years, there has often been a 
margin of 2 to 3 cents a pound between purchase price of calves at 
weaning time and selling price in the spring. Under such conditions, 
with the current prices of feedstuffs, the feeding of calves for the 
market has been very profitable. 
The work of 1916-17 indicates that calves too young to wean and 
fatten for market in the fall can be made to pay a nice profit by 
letting them nurse the cows during the winter, feeding them grain 
on grass the following summer, and selling them in the fall, or by 
following the summer feeding with a short feeding in the dry lot and 
selling about Christmas or soon after.
