PARASITIC DISEASES OF THE HORSE. 4iil 



Symptoms. — AVhen the worms exist in small numbers they 

 present little or no symptoms. If present in large numbers, 

 there will be symptoms of abdominal pain. Wasting in appear- 

 ance, the animal becomes i)()t bellied, with recurrent depraved, 

 voracious appetite, dryness of the skin, and constipation, suc- 

 ceeded by diarrhoea. In some cases nervous symptoms will be 

 presented. The owner may generally notice that the animal is 

 passing worms. The prognosis is favorable. 



Treatment. — Good water and good food are essential. Clear 

 the bowels by giving a dose of oil or six drachms of aloes. Then 

 give oil of turpentine, two, three or four ounces in a pint of lin- 

 seed oil. Follow for seven days wnth similar treatment. A sharp 

 cathartic should be given on the eighth day, such as aloes, eight 

 drachms. Santonin in one to two drachm doses may be given. 

 Another remedy is highly spoken of, as follows: Pulverized 

 antimony tartar, one-half ounce; calomel, one-half drachm. Oil 

 of Felix mass, one drachm; oil of savin, one drachm; pulverized 

 ginger, one drachm; turpentine, one ounce, is also a good remedy.

 are found in the large intestines, and in great numbers. They 

 inhabit the colon, being very abundant in the flexures of that in- 

 testine, but are more numerous in the rectum. They escape by 

 the anus, and cause irritation by the horse rubbing its tail against 

 any hard substance, or suddenly lifting the tail and turning it or 

 switching while traveling. There is a yellow incrustation around 

 the anus and adjacent skin, formed by eggs of the worms dis- 

 charged from the body. 



Treatment. — It is very diflficult to destroy these parasites. 

 Injections of common salt in solution are beneficial. Three ounces 

 of turpentine and common oil should be given daily for several 

 weeks. Tincture of aconite in the usual doses may be tried.
