they will not come through. You can have a good deal of 

 trouble with these things. If we make any attempt to cut, we 

 injure the teat. The best method is to use the milk tube until 

 they disappear. We have instruments to introduce into the 

 teat, but they usually do more harm than good. All that is 

 necessary to do in such a case is to draw the milk off with the 

 tube, until these small objects disappear, which they will. 



We have another disturbance in the teats, a form of skin 

 disease, called acne, which gives a great deal of trouble. It is 

 mistaken for cowpox. There is a great difference between that 

 and acne. Acne is sharp at the point. Cowpox, when it starts, 

 goes up like a perpendicular wall. It usually rises one-eighth 

 inch above the surface, and after the third day serum exudes, 

 leaving a hollow in the center. We can tell the difference in 

 that way. Cowpox exhausts itself in about three weeks' time 

 and does not return. Cowpox never affects the animal the 

 second time. If a cow having cowpox is standing in the barn 

 with the others, they will not take the disease. It is only gotten 

 by contagion or by rubbing in. This trouble, acne, will appear 

 on the teats and udder of the cow, and sometimes on the inside 

 of the hind legs, and when one crops goes away, another crop 

 makes its appearance, and will go on from one month to another 

 and sometimes longer, and is very troublesome. The best way 

 to treat this disease is to give internal medicine. With cowpox 

 we do little but milk with the milk tubes, you can't stop it. Acne 

 is a condition of the system, necessitating giving the cow a dose 

 of medicine internally. We give 1 ounce Fowler's solution of 

 arsenic at a dose twice daily in her food for five or six weeks. 

 It has no action on the milk the cow gives. 



These are the principal things we find connected with the 

 udder of the cow, with the exception of some internal things. 

 The cause of the cow's giving bitter milk is due to some chemical 

 change in the udder that it not well understood. You will some- 

 times find benefit from giving a dose of physic and changing the 

 food. 



Any questions about the udder that you would like to ask?
