240 PARASITIC DISEASES 



thoroughly cleaned and disinfected. This is necessary in order 

 to destroy lice that have become scattersd about by the lousy 

 animals, and prevent the reinfection of the treated animals. 

 The best method to use in cleaning the quarters is to remove all 

 litter and manure from the stable or houses and their immediate 

 surroundings. It should be burned, or hauled to a field or lot 

 where other animals cannot come in contact with it for a few 

 months. The walls, floors and partitions should be sprayed 

 with a three per cent water solution of liquor cresolis compositus. 

 Lime may be scattered about the buildings, yards and runs. 

 The most satisfactory method of destroying lice on the bodies 

 of animals is by washing or dipping in a water solution or 

 mixture of some reliable disinfectant or oil. 



Running hogs through a dipping tanh that contains a one 

 or two per cent water solution of liquor cresolis compositus, or a 

 coal tar disinfectant, or that has from three-fourths to one and 

 one-half inches of oil on top of the water, is the most satisfactory 

 method of destroying the hog louse. Because of the thinness of 

 the hog's coat and the danger from irritating the skin when 

 strong solutions of a disinfectant are used, most swine breeders 

 prefer crude oil as a remedy for lousiness in hogs. Crude oil 

 may be applied to the bodies of hogs with a swab. If this method 

 is practised instead of dipping, it is advisable to crowd the 

 hogs into a small pen, and apply the oil in front and between 

 the thighs and back of the arms. This may be practised during 

 the cold weather when it is impossible to dip the animals. 



Horses may be )vashed with a one or two per cent water 

 solution of liquor cresolis compositus, or a coal tar disinfectant. 

 If the weather is cold, it is advisable to pick a sunny day, and 

 blanket tlie animal after rubbing it as dry as possible in order to 

 prevent chilling and catching cold. 



Cattle may be treated in the same manner as horses. Mercu- 

 rial ointment rubbed in small, amounts on the skin back of the 

 horns and ears, where the animal cannot lick it, is a common
