68 REPORT ON EXPERIMENT STATIONS, 1952
These investigators believe that true spontaneous ketosis in dairy cows
is due to adrenal gland deficiency. This gland in turn is probably
deficient because of improper functioning of the pituitary gland. The
investigators have found that cortisone and ACTH are about equally
good in correcting both these deficiencies and in bringing about an
incidental increase of blood sugar and promoting recovery within a
relatively short time, depending on the size of dose. This action, of
course, applies to uncomplicated, spontaneous ketosis. Feeding sugar
or molasses during the dry period did not effectively prevent ketosis,
but it is thought that this treatment is helpful for the first few weeks
following calving in those herds in which the incidence of ketosis is
Wisconsin dairy specialists may have found a low-cost cure for
ketosis. They want to test the material further before they make any
recommendations, but an inexpensive salt called sodium acetate looks
very promising. This discovery arose from research on rumen digestion.
The changes in the fatty acids of the rumen and the effect on
milk production suggested that there is a possible relationship between
these acids and ketosis, which results from an upset of the fatty acids
of the blood stream. Since sodium acetate had been successful in correcting
the low test caused by fatty acid upset in the rumen, the dairy
specialists reasoned that it might also help to correct the fatty acid upset
in the blood stream and thus cure the disease. Several cows with
ketosis were fed 1/4 to 1 pound of the salt and most of them have recovered
from the disease. However, the dairy specialists are urging
caution in the use of the chemical. It will not cure all cases of
ketosis-especially if there are complicating conditions. The scientists
are encouraging veterinarians to try sodium acetate and to report
their results. If the treatment works, it could save millions of dollars
each year in Wisconsin alone.
New York (Cornell) reports that sodium propionate, a white powder
used as a mold inhibitor by bakers, has brought about recovery in
cows suffering from this condition. Affected cows apparently use
this substance to increase the amount of sugar in their blood. Tests
indicated that one-half pound of sodium propionate per day for 10
days is sufficient for a cure and is relatively inexpensive.
Liver Fluke Infection in Cattle
It was previously reported that as a result of its Island-wide survey,
the Puerto Rico station found that in 1 year more than 6.24 percent
of cattle livers (total weight of diseased livers estimated at 45,871
pounds) were condemned because of liver fluke infestation. The station
has continued its study and reports promising results from the
use of an intradermal (skin) test for diagnosis of the infection in
cattle. So far 94 percent of 87 such tests performed have conformed
with the findings on physical examinations of livers from freshly
slaughtered cattle. Use of the test may help in the maintenance of
fluke-free herds and thus reduce to a minimum the losses due to liver
infestation and the resultant, unfavorable influences on milk and meat
production. The test will also indicate which animals should be
treated and when to treat them.
