CHRONIC CATARRHAL ENTERITIS IN CATTLE. 



Causes : As in acute chest diseases, abdominal tuburculosis. Lesions : 

 Thinning, discoloration, degeneration of mucosa, foetid, mucous contents, 

 black, baked masses, lymph glands pigmented. Symptoms : Impaired 

 appetite, irregular bowels, tympanies, lies with nose on right flank, un-
