COCOANUT MEAL AS A DAIRY FEED.
BY JOHN M. SCOTT.
In recent years the manufacture of cocoanut oil on a large scale from
the dried "meat" of the cocoanut (copra) has given a by-product known as
cocoanut meal. This material has been placed on the markets as a dairy
food. A chemical analysis of the cocoanut meal with which our experi-
ments were conducted indicated that its apparent feeding value was in
excess of half that of cottonseed meal.
CONDITIONS OF THE EXPERIMENT.
Four cows were selected from the dairy herd and divided into two
lots, so that the period of lactation in each lot would be as nearly com-
parable as possible. The feeding time was divided into three equal periods
of twenty-one days each, with seven days preliminary feeding before each
of the three periods, so as to change the feeding gradually. Each lot
received the same amount of bran and shorts; but the cottonseed meal and
cocoanut meal were not fed- in equal, but in equivalent rations, which were
calculated from the results of the chemical analysis.
The experiment proper lasted sixty-three days, during which time the
cows which were fed -with cottonseed meal produced 1,888.5 pounds of
milk, and the cows which received cocoanut meal gave 1,844 pounds of
milk; so that the balance in favor of cottonseed meal was only 44.5 pounds
for the whole period, or an average of a little more than 11 ounces a day.
(One gallon of milk weighs 8.6 pounds.)
From the above results, we find that one pound of cottonseed meal is
nearly equal to two pounds of cocoanut meal for milk production. This
corresponds nearly to the results of the chemical analyses of these two ma-
terials. In other words, our experiments indicate that a unit of protein
from cocoanut meal is very nearly, but not quite, equal to a unit of protein
from cottonseed meal.
In this experiment the total amount of feeds consumed were as follows:
First Test-Cocoanut meal, 453 pounds; bran, 1,008 pounds; shorts,
1,008 pounds. Second Test-Cottonseed meal, 252 pounds; bran, 1,008
pounds; shorts, 1,008 pounds.
March 21, 1908.
One pound of cottonseed meal with the proper amount of bran and
shorts produced 7.49 pounds of milk; while one pound of cocoanut meal
with the corresponding amount of bran and shorts produced only 4.06 pounds
So far as we are able to detect, the cocoanut meal had no bad effects
on the general health or constitutions of the animals. After the first few
feeds the cows all seemed to relish the cocoanut meal, and apparently ate
it as heartily as they did cottonseed meal. .The cows were weighed at
regular intervals, and a comparison shows that they all gained a little in
weight during the period of the experiment.
The test reported here was not conducted during the best season of the
year for the dairy cow. The hot weather of July and August, when ac-
companied by an abundance of flies and mosquitoes, is not conducive to a
good yield of milk. This, no doubt, accounts in part for the low daily
average yield per cow, which was a little less than two gallons. This is
what would be called only a fair yield for a good dairy cow. A good cow
ought to give an average of 2.5 gallons of milk a day.
