Thirty-fourth Annual Convention. ^^"^ 



The unfavorable termination of mastitis is abscess forma- 

 tion or gangrene of the part. Should an abscess form it should 

 be lanced as soon as possible and the contents evacuated. The 

 cavity should be injected with antiseptics till the wound has 

 healed. 



Gangrene. 



Gangrene is where a part or all of the gland dies. This 

 disease often terminates fatally where a large portion of the 

 gland is involved. The affected part becomes blue or purple 

 red, cold, and sensation is partly or entirely gone. The milk 

 from the affected part is dirty brown in color and has a putrid 

 odor. 



Treatment. 



The treatment in cases where the disease is well developed 

 is of little avail. Antiseptics internally and externally should 

 be used freely. 



Cow Pox. 



There is a contagious disease that attacks the udder and 

 teats or cows known as cowpox (variola.) This is a form of 

 inflammation of the udder that principally involves the skin, 

 although it may affect the deeper tissues. It is characterized by 

 the formation of small vexicles or blisters which contain a straw 

 colored fluid. These vexicles pit, or a depression is formed in 

 them after three or four days ; this is followed by the formation 

 of a yellow pus which dries down into a scab. The sore slowly 

 heals and after a few days the scab drops off. Where these 

 blisters form on the teat they are usually broken by the hands of 

 the milker and a raw sore is formed which heals very slowdy on 

 account of the constant irritation from milking. 



Treatment. 



Cowpox usually runs a short course and terminates in 

 recovery, so the only treatment called for is that which will 

 assist in healing up the sores; strong carbolized vasaline is 

 perhaps as good as anything. Caustics may be applied where 

 the sores become indolent. 



The preventive treatment in this malady as well as in con- 

 tagious mastitis is far the most important. The well animals 

 should be separated from the disease and the affected cows 

 should be milked last.
