226 Diseases of Poultry 



of the less irritating ointments recommended for scaly legs 

 (see p. 222). 



The following list gives some ointments in the order of 

 their desirability for use on the body. 



Oil of caraway ointment (1 to 5). 



Balsam of Peru. 



Creolin treatment (1 to 10). 



Helmerich's ointment. 

 Salmon gives a modification of the latter ointment which 

 he considers an improvement for use in depluming scabies. 



Flowers of sulphur, 1 dram, 



Carbonate of potash, 20 grains, 



Lard or vaseline, | ounce. 

 Scabies may also be cured by liquid applications. The 

 two following preparations are recommended by Salmon : A 

 solution of balsam of Peru in alcohol (1 part of balsam to 

 3 of alcohol) or 1 dram of creolin, 2 ounces of glycerine, \ 

 ounce of alcohol and \ ounce of water. Either of these 

 liquids are applied by rubbing into the skin. The applica- 

 tion should be repeated every 4 or 5 days until the disease is 

 cured. 



Other Mites Affecting Poultry 



Another form of Body Mange or scabies is found asso- 

 ciated with the mites Eiyidermoptes bilobatus and Epider- 

 moptes bifurcatus, but it has not been certainly demonstrated 

 that they are the cause of the disease. Present evidence 

 indicates that they are. 



The disease closely resembles favus (p. 223), but usually 

 does not affect the head. The regions commonly attacked 

 are the neck, breast, the wings and the body under the wings. 

 It sometimes affects the entire body, including the head. 

 The skin becomes irritated and shows an accumulation of 

 scales or crusts especially at the base of the feathers.
