180 DISEASES OE THE DIGESTIVE SYSTEM. 



dmbiUcal Bcmia. 



Umbilical Hernia is very common in tlie sheep, and rarely 

 if ever causes any inconvenience. 



■Creatmcnt. 



Where rupture threatens the life of the animal through 

 strangulation it had better be sold to the butcher. Umbilical 

 hernia as seen in sheep, while unsightly, is seldom serious and in 

 no case would an operation for this trouble in sheep be justified. 



Stricture. 



In the bowel occurs as a result of changes in the tissues of 

 the bowel, resulting from acute inflammation, chronic thickening 

 and degeneration of its walls, which by constricting the tube, 

 acts as a mechanical obstruction to the passage of faecal ma- 

 terial. This complaint is rare, and when occurring in sheep 

 has no differential symptoms to distinguish it from inflammation 

 of the bowels, which it virtually causes. 



It is always fatal. No treatment. 



Tolvulus. 



Is a twist or alteration from natural position of part of the 

 bowel, generally the ileum twisting round the colon. !No treat- 

 ment or diagnostic symptoms. Always fatal. 



Intus-Susception. 



Is when one part of the bowel slips into the part posterior 

 to it. It may be likened to the finger of a glove, half turned 

 inside out. This is supposed to occur from violently increased 

 bowel motion, (peristalsis). This also is a fatal affection, with no 

 particular diagnostic symptoms. In all the above enumerated 

 troubles the symptoms simulate those of inflammation of the 

 bowels, there being intense nervous prostration and nausea, with 

 an absence of bowel sounds or miirmurs, scientifically called bor- 

 borygmus. ]^o treatment.
