Prevention is more important than treatment in any case where it can be secured; because it is surer; it is cheaper; and is usually much easier to administer than medical FIG. 72. A PLAIN CASE OF SHEEP SCAB. The spread. —Whether the disease spreads rapidly over the body or not depends to some extent upon the thriftiness or un- thriftiness of the individual animal. When sheep are fat and the wool is well supplied with yolk this disease spreads slowly, and is much less serious. It should be borne in mind that sheep cannot have scab unless the mites first reach the surface of the body. The infection is frequently made when one sheep rubs against posts or fences where scabby sheep have previously rubbed. In the latter case the mites are first transferred from the diseased sheep to the post, and then from the post to the healthy sheep. In other cases the mites are transferred when a diseased sheep rubs against a healthy one. Digitized by Microsoft®.
