Garget. 145 



or of the milk ducts into the udder tissue where they 

 cause inflammation. Such physiological troubles are 

 usually confined to a single animal, and the swelling and 

 fever are generally temporary. In well developed cases 

 the milk is likely to contain flakes of slimy clotted ma- 

 terial. If the inflammation persists, the milk secretion 

 may cease altogether and only a yellowish liquid be ob- 

 tained. If the attack is of short duration, no permanent 

 harm is likely to result, the normal flow of the diseased 

 quarter may be restored during the same lactation period 

 or at the beginning of the next. A prolonged attack is 

 likely to cause a loss of the quarters involved. 



A much more serious type of garget is that known as 

 infectious or contagious garget, which is caused by cer- 

 tain bacteria which are able to grow in the udder and 

 cause serious trouble. This form is much more import- 

 ant than that caused by cold or wounds as it is very likely 

 to spread from one animal to another. The milker is 

 usually the cause of the spread of the trouble in the herd. 

 An animal that has garget in any form should be milked 

 last or the hands should be washed in a disinfectant 

 such as can easily be made by the use of the corrosive 

 sublimate tablets that can be obtained at any drug store. 

 It is also advisable to remove the animal from the stable. 

 Through carelessness a large part of the herd may be- 

 come infected. 



The milk from animals having inflammation of the 

 udder, no matter how slight it may be, should not be 

 mixed with that from healthy animals. It should be 

 thrown away.
