§ 22. No disinfection is required for dourine and vesicular exanthema. 



Mange [Scah] 



§ 23. 1. During the treatment of the diseased or suspected horses or 

 sheep, or of sheep flocks in which the disease exists, the stables, hurdles, 

 equipment, utensils, blankets, cleaning implements and other objects which 

 have come in contact with such animals are to be cleaned and disinfected. 

 When the animals are treated by dipping, the cleaning and disinfection is to 

 be carried out at each dipping. If the animals are treated by hand applica- 

 tions, the cleaning and disinfection is to be repeated at shorter or longer inter- 

 vals according to the degree of the disease. After the completion of the 

 curative treatment, the final disinfection is to be made. 



2. Stables or other compartments and hurdles used by horses or sheep 

 affected with mange before slaughter, or before treatment was begun, must 

 be immediately cleaned and disinfected after the diseased animals are 

 removed. 



3. The disinfection is carried out as directed in § 14. As disiafectants, 

 dilute cresol water, carbolic acid solution or lime are to be used. Special 

 attention is to be given to all objects with which the diseased or suspected 

 animals have come in contact (mangers, racks, posts, pillars, stalls, tie ropes, 

 halters, harness, saddles, cleaning instruments, blankets, housing, clothes of 

 attendants, wagon poles, etc., in connection with horses; hiu-dleB, racks, 

 mangers, posts, sheep folds, sheep shears, shovels, manure, clothing and foot- 

 gear of the attendants, etc., in connection with sheep). 



4. The manure from the infected stables is to be removed to the field 

 and immediately plowed under. If the latter cannot be done at once, the 

 sheep are to be kept away from the manure until the work is finished.
