308 DISEASES OF CATTI.E. 



Sturdy. — (See Hydatides.) 



Teats. — Teats of milch cows are often subject to diseases 

 and derangement. 



1st. Milk stones sometimes stop the flow of milk, and 

 are felt within the milk channel, when the teat is pressed 

 •between the fingers. For their removal, take a silver 

 probe or knitting needle, and, if possible, force the obstruc- 

 tion up into the udder. 



2d. Strictures of the milk channel of the teat cause a 

 small stream of milk to flow, and impair the usefulness of 

 that quarter of the udder. This can also be remedied by 

 using a silver probe or needle, commencing, however, with 

 a small size, and gradually using thicker or larger ones, 

 till the channel is as large as wanted. This operation will 

 have to be carried on for a week or two, the first day using 

 the small probe three times in the day, and following the 

 next day with the larger size, and so continuing with other 

 sizes, till finally cured. 



3d. Warts are of occasional trouble to the cow, and to 

 those who milk her. Irritation, and sometimes swelling 

 is induced, which cause closure in the channel of the teat. 

 Warts are to be removed by a pair of sharp scissors. 



MILK SYPHON. 



4th. Sore teats are cured by the simple ointment, one 

 ounce, and one drachm of the rust of copper, commonly 

 called verdigris, added to it. The milk can be drawn from 

 the teat by means of a tube, as is shown by the above 

 illustration, called a milk syphon.
