290 REPORT OF THE FARM SUPERINTENDENT OF THE 
WARM WATER FOR MILCH COWS. 
An experiment was planned for warming water for cows to get 
some idea of its influence on the yield of milk early in the winter, 
but the only cows available for the purpose were so far advanced 

from calving that there could be little hope of affecting their flow _ 
materially. Hence the experiment was deferred until a cow came — 
in fresh, and she was paired with a heifer milking with her first 
calf. Their feed was to have been of the same hay and grain 
mixture, differing only in the amount eaten. One was to have 
water at the temperature at which it entered the stable (36° F.), 
while to make the contrast as great as possible and relieve the 
other from too much work warming water, the temperature was to _ 
be raised to 96° F. No roots or silage were to be allowed in order ‘ 
that all the water consumed should be taken directly and thus 
help in the trial. During the first few days on the dry food it was 
feared that sufficient hay would.not be eaten, so for two days — 
stover was offered, but so little was desired that it was dropped — 
and the hay increased until it was certainly enough for the wants — 
of the animal. 
When the cow Juno dropped her calf she was given warm water 
and manifested considerable eagerness for it, so when she had 
fairly begun giving a full flow of milk the experiment was begun. 
The heifer Belle has always shown a disposition to be shy and: : 
to resist anything like familiar approach. This quality soon — 
showed itself in a refusal to drink from a pail and time was lost — 
in teaching her by thirst to drink from a vessel in which the 
weight of water consumed could, be’ determined. ‘hus it was_ 
_ March fifth when the experiment was fairly started. 
Belle seemed disturbed and out of condition, and on the ninth 
sugar beets were added to her diet, but when it came to change 
her to warm water it was refused and she was thrown out of the 
experiment entirely. — 
May, another heifer that had dropped her first calf February — 
twenty-seven, four days after Juno dropped hers, was thought of — 
to take Belle’s place, but she at first had some swelling in her 
udder and could not be fairly used. She was, however, given 
- warm water during Juno’s cold water period but was continued 
no longer as the temperature of the air was rising and it seemed 
impracticable to carry the trial later. 
In order to warm the water conveniently a wooden box lined 4 : 
with galvanized iron was adapted for use. The box was twenty-
