CONDITIONS INCIDENTAL TO PREGNANCY. 49. 
bones are enlarged, friable and brittle. This condition 
has been noticed in Mares, Cows, and Ewes, as well as 
Bitches and Swine. 
The cause is due to an insufficiency of food,. or to 
food that is lacking in mineral and nitrogenous 
elements. 
The treatment is, to supply food rich in the con- 
stituents required, and medicinally, nerve tonics and 
preparations of calcium. As a preventive, animals 
should not be bred from too young. 
CGidema. 
Serous infiltration into the connective tissue, at 
different parts of the body of pregnant animals, the 
Mare being the principal victim. The condition is 
most marked in primipare, and appears much later in 
better bred animals, than in those of coarse breeding 
and lymphatic temperament. The cedema commences 
at the lower part of the hind limbs, gradually ascending 
to the hocks, or higher, and may extend to the 
dependent parts, such as along the floor of the 
abdomen, mamma, chest, and fore-arms. 
The condition is said to be due to pressure of the 
foetus on the pelvi-crural vessels, and to an anemic 
condition of the system. The large mammary veins 
of the Cow, allowing of free return of blood from the 
hind limbs, is considered the reason why this animal 
is exempt. 
Exercise and hand-rubbing are generally all that 
is necessary, the swelling disappearing a day or two 
after parturition.
