the cattle scab and the symptoms are similar. Shedding of the 

 wool in patches is an advanced symptom in sheep while a ragged 

 condition of the wool shows earlier. 



Control of sheep' scab, as of cattle scab, is accomplished by 

 dipping, the same dips being available for both. 



Mange and Scabies of Horses * 



Scabies of horse's is a disease similar to the scabies in cattle. 

 Mange is caused by a mite of a different genus, (Sarcoptes scabei) . 

 The species involved has several varieties, named to indicate the 

 host. Thus the one on horses is equi, on dogs it is called cam's, on 

 hog suis, while the same mite is hominis on man. The mites may 

 be transferred from one host to another but generally do not live 

 long except on the original host. The disease caused by the mange 

 or itch mites does not differ materially from the ordinary scabies. 

 Earliest indications of infection are a tendency to rub affected 

 parts, the hair being entirely rubbed off in spots. 



Treatment of mange or scabies in horses, consists of rubbing some 

 solution such as is used in dips into the skin of the affected parts, 

 being sure that the entire infected area is treated and repeating the 

 process three or four times at intervals of about four days. Lime- 

 sulphur solution, as recommended for dipping, is as convenient 

 and satisfactory as anything. Nicotine preparations will also 

 be found to be effective. 



Swine Mange 



Swine mange manifests itself usually on the upper parts of the 

 body from head to tail. A general roughened and unhealthy 

 appearance of the skin will suggest the existence of the disease. 

 This may be confirmed by the finding of the mites. This is done 

 by scraping off the skin until some of the deeper layers are reached 

 and examining with a microscope. 



Treatment consists of dipping or local application of some of 

 the dips sold for the purpose or of home made lime-sulphur solution. 

 If the animals are dipped the dip should be kept at about body 

 temperature. 



Ticks Attacking Cattle * 



Several species of ticks attack cattle and others are occasional 

 parasites -of other animals and may be found on man. Perhaps
