use on children is obtained from heifers that have cow pox. To 

 prevent the spread of cow pox in a herd the affected animals 

 should be the last ones milked and the hands of the milker 

 should be disinfected when he is through milking. 



TUBERCULOSIS OF THE UDDER. 

 Tuberculosis of the udder is not very common but when it 

 occurs it manifests itself in the shape of hard, slightly tender 

 lumps in some part of the glands. These grow more or less 

 slowly until finally the whole quarter may be filled. In the 

 meantime the milk is normal in appearance and only gradually 

 decreases in quantity. It is needless to say that such milk is 

 unfit for food and the only treatment for the trouble is to 

 destroy the cow. 



GARGET. 



Garget is one of the most troublesome diseases that the dairy- 

 man has to contend with. It results in the loss from the dairy 

 of many otherwise valuable cows. In its mildest form it mani- 

 fests itself in a scant supply of milk from one quarter of the 

 udder. This milk will contain some thick, stringy particles that 

 may only be discovered when the milk is strained. In more 

 severe cases all the quarters of the udder may be seriously 

 swollen and hot and the secretion of milk almost entirely sus- 

 pended. The cow will also be stifif and lame, with little appe- 

 tite. Garget usually results from mistakes in feeding, such as 

 sudden changes in the quantity or quality of feed. But it is 

 also produced by direct injury to the udder, as lying on an 

 uneven floor or a stone in the pasture. Some rough milkers 

 have more trouble with garget than more careful milkers. 

 Treatment is not always very satisfactory. Old cows that have 

 had frequent attacks of garget are often best treated by sending 

 them to the butcher. From the first attack, even although it is 

 severe, the cow usually recovers within a few days as the result 

 of a moderate dose of physic and daily doses of an ounce of salt- 

 peter, with light laxative food. Sometimes satisfactory results 

 follow the distending of the udder with sterile air as in milk 

 fever. This is nearly always beneficial when there is consider- 

 able thick milk in the udder that cannot readily be removed. 

 Contagious garget is due to the growth in the udder of certain
