CONDITIONS INCIDENTAL TO PREGNANCY. 49 



laones 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. 



CEdema. 



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 primiparse, and appears much later in 

 better bred animals, than in those of coarse breeding 

 and lymphatic temperament. The oedema 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, mammae, chest, and fore-arms. 



The condition is said to be due to pressure of the 

 foetus on the pelvi-crural vessels, and to an anaemic 

 ■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 

 ^fter parturition.
