/BATTLE LICE are injurious to all classes of cattle, 

 V/ but the greatest losses occur in young stock and 

 poorly nourished old animals. The losses are caused 

 by irritation, digestive disturbances, arrested growth, 

 low vitality, and increased death rate. 



Three kinds of lice are commonly found on cattle, 

 and all three species may be present on the same 

 animal at the same time. The same method of 

 treatment may be used for the three species. 



Methods of treatment include hand applications, 

 spraying, and dipping. The first two methods are 

 suitable only for small herds. Dipping is the best 

 method of applying treatment. 



Arsenical dips, coal-tar creosote dips, and nicotin 

 solutions may be used for dipping cattle to destroy 

 lice. Two or more treatments should be given 15 to 

 16 days apart. 



Plans of cattle-dipping plants and directions for 

 building vats and dipping cattle are given in this 

 bulletin.
