382 DISEASES OF HORSES AND CATTLE. 



anus and dries there causing an itchiness and the 

 animal will frequently rub its tail. It will eat 

 large quantities of food and become pot-bellied. 

 In some cases^there will be colicy pains and more 

 or less bloating. No matter how good the food 

 may be or the quantity eaten the animal still re- 

 mains in poor condition. When ^the above symp- 

 toms are present a watch should be kept, for very 

 likely a worm or two will be discovered in the 

 feces. We may then, with a degree of certainty, 

 suppose that worms are the cause of the trouble. 



Treatment: There are a number of substances 

 used for the dislodgement of these worms. Give 

 the horse two ounces of turpentine in half a pint 

 of raw linseed oil at a dose on an empty stomach 

 morning and night for three or four days, then 

 give one quart of raw linseed oil as a physic. An- 

 other good remedy is to mix two drams of asa- 

 fetida, one dram of calomel, one dram of savin 

 and two drams of the fluid extract of the male 

 shield fern and make into a ball and give at night 

 on an empty stomach. A bran mash can be given 

 two hours after the ball and on the following 

 morning one ounce of aloes as a physic. This is 

 a very effectual remedy. When one has not time 

 to lay up his horse benefit is sometimes obtained 

 from giving him two drams of sulphate of iron and 

 half an ounce of gentian at a dose morning and 

 night in a bran mash if the horse will take it; if 

 not, put it into a quart of gruel and give as a 

 drench; continue tjiis for a week.
