Fhikes in the Liver 341 



appear gradually and increase in severity until the 

 animal dies from general emaciation. 



The first symptom noticed is that the animal is out 

 of condition; the skin and mucous membranes are pale, 

 the hair or wool is dry or rough, the appetite is lost, 

 and the animal drinks large quantities of water. Drop- 

 sical swellings appear in dependent parts of the body. 

 The bowels may be constipated or there may be profuse 

 diarrhea. These symptoms become more aggravated 

 until death takes place. 



Microscopic examination of the discharges from the 

 bowels will often reveal large numbers of the eggs. 

 After death, the liver is found to contain diseased, 

 yellowish nodules, each of which contains one of the 

 flat, ovoid flukes. 



The most satisfactory treatment is to prevent the 

 disease by removing the animals to uninfested pastures, 

 especially to those which are high and dry, and allowing 

 them only pure fresh water. In the early stages of 

 the trouble, an abundance of nutritious, easily-digested 

 food will do much to assist in overcoming it. Salting 

 the animals daily with a mixture of one part sulfur 

 to six parts of common salt is also good. Medicines, 

 except in the way of tonics, are of little value in the 

 treatment of this disease.

 are caused by the presence of small round worms
