326 DISEASES OF SHEEP. 



been more prevalent within the last thirty years than 

 previous to that time, which is accounted for to some 

 extent in the varieties and breeds of sheep and in the 

 increasing number. So much is this so, that farmers can- 

 not find highland pasture sufficient for them, and they are 

 brought down and put on moist lowland pasture, where 

 they can find plenty of food without travelling much ; 

 hence, the growth of horn is more than the wear, or the 

 supply more than the demand. Subsequently the horn 

 becomes over-grown and turns upon the sole, and bruising 

 the sensitive structures, earth and sand soon find their way 

 into the cavities produced, causing inflammation of the 

 laminae, lameness, and secretion of fetid pus. 



Causes. As before stated, it results from an increased 

 supply of horn which turns up from the toe, pressing upon 

 and irritating the sensitive structures of the foot. 



This affection of the feet is almost certain to follow the 

 removal of heavy bred sheep, such as the black-faced 

 Cheviot and Southdown, from their native and upland 

 pastures to rich meadow and arable lands. Their native 

 Avalks being rough and rugged — the grass not so plenty, 

 which insure the sheep walking over a large tract of land 

 in order to procure their food — hence the waste and supply 

 of hoof is balanced. 



Treatment. AVhenever the sheep is observed to go lame, 

 it must be caught and the feet examined. Remove all 

 filth and sand ; then cut off every loose and unsound 

 jDortion of horn Avith a stout pocket knife, and apply the 

 following to the sore parts : Oil of turpentine, two ounces ; 

 sulphuric acid, half an ounce; olive oil, one ounce; mix. 

 To be applied with a small piece of sponge or cloth on the 

 end of a stick ; or a goose feather will answer very well. 

 If sores occur on the digital space (divisions) or elsewhere.
