ROUND WORMS 



ROUND WORMS are the larger kind usually found in horses, 

 and when full grown are six to fourteen inches in length. They usually 

 inhabit the small intestines; when many are present the animal loses 

 condition, gets pot-bellied, has a rough coat, capricious appetite, shows 

 a tendency to eat dirt, with occasionally a colic or diarrhoea, and pres- 

 ence of worms in the dung. The riddance of a horse of these parasites 

 is not very difficult if a thorough effort is made to dislodge them. In 

 order to get the best effects the animal should be starved before giving 

 the drugs, which may be as follows : 



National Vermifuge — 1 tablespoonful. 

 Common Charcoal — 3 tablespoonfuls. 



mixed and given in the feed three times a day, followed by a dose of 

 aloes, or : 



Two ounces turpentine, one pint new milk, given three successive 

 mornings on an empty stomach. The fourth morning give two drachms 

 Tartar Emetic in a pint of raw linseed oil ; if the horse has to be worked 

 steadily the following powders will be useful : 



Powdered Copperas — 1 ounce. 

 Powdered Bluestones — 1 ounce. 

 Powdered Sugar — 2 ounces. 



Mix and make into twelve powders, one to be given twice daily in the 

 feed. 



Worms are not common in cattle ; in sheep are the frequent cause 

 of losses and occasionally so in pigs. 



STOMACH WORMS, usually found in lambs, are the most 

 serious and most common. They are very small, one-quarter to 

 one-third of an inch long, pale reddish in color, and are found in the 

 fourth stomach only. Lambs affected are thirsty, pale in the ^yes, 

 lose weight, are dull, lose their appetite, may scour or eat dirt. Ben- 

 zine or gasoline, two to four drachms in six ounces of new milk, 

 given three mornings in succession on an empty stomach, have been 

 highly recommended ; creolin and milk in similar doses may also be 

 used. National Vermifuge for sheep should be mixed vi^ith plenty 

 of salt and placed in the salt troughs. 



TAPE WORMS when present cause symptoms similar to those 

 described for stomach worms. In addition, paleness of the skin and
