MILK FEVER IN COWS

This disease affects cows only among domestic ani-
mals. Its attacks are almost entirely confined to cows
when giving birth to the third, fourth, fifth or sixth calf,
that is, to cows whose energies have become centered on
the production of maximum quantities of milk. One of
the chief causes, therefore, is a plethoric condition of the

system in cows of mature age and that are great pro-
ducers of milk. The other predisposing causes include:
Easy delivery; high temperatures in stables; a costive
condition of the system, and lack of exercise. Among the
symptoms that indicate the approach of the disease are
uneasiness, accompanied by switching of the tail, a stupid
or wild condition of the eye, sudden constipation and a
checked milk flow. As the disease progresses, the cow
lies stretched out in a torpid or semi-torpid condition.
Among the preventive measures are: A spare diet, light
and laxative, before calving for about a week; ample
exercise and a mild laxative from 2 to 5 days of the calv-
ing, as a quart of linseed oil or a pound of Epsom salts.
This, together with the daily use of Pratts Animal
Regulator, will usually effect a cure.
The pumping of atmospheric air filtered and steril-
ized and well boiled water is very efficacious. This treat-
ment can be obtained by the use of Pratts Milk Fever
Outfit for Air Treatment. The price is $3.
