AILMENTS OF COWS AT CALVING TIME 81 



substance. There is little or no pain on handling, 

 practically no secretion of milk ; simply a gradual 

 drying up and destruction of that quarter. In 

 tuberculosis the disease usually assumes a chronic 

 type from the onset, there being a slight hard en- 

 largement at the top of the gland which gradually 

 extends down until the whole of the quarter is 

 destroyed. Ticks are also a common cause. 



Treatment. Avoid the various causes, for in the 

 chronic form little or nothing can be done. In the 

 acute state suspend a poultice made of bran on to 

 the cow's udder by means of tapes over her quarters 

 and simply cutting holes to allow the teats to pro- 

 trude. Do not make the poultice too hot. The 

 udder may be thoroughly bathed with hot water, 

 but this is of little value unless thoroughly done 

 several times a day and for about twenty minutes 

 each time, after which the udder should be kept 

 warm. It is sometimes of value to rub in an oint- 

 ment such as belladonna or camphorated oil. The 

 teats should be regularly stripped three or four 

 times a day even if there is not any milk. This 

 may prevent the formation of abscesses, and in the 

 case of recoveries stimulates secretion of milk. 



Gangrenous Mammitis. 



This is usually a sequel to acute inflammation of 

 the udder, and unless attended to usually causes the 

 death of the animal. In this condition the udder
