a day in her food. Diarrhoea in pigs is also present in cases of tuber- 

 culosis. 



283. Worms. — As a rule pigs do not suffer so much from worms 

 in the intestinal canal as might be supposed, considering the animal's 

 filthy habits. There are, however, several kinds of worms found in 

 the pig, the most common being the Ascaris suilla, a worm creamy 

 white in colour, and varying from 3 to 7 inches in length, which is 

 found in the stomach and small intestine, and is of the nematode or 

 round worm order (Plate XIX.). Symptoms. — When infected with 

 worms, the animal is restless and hide-bound, with the skin dirty, dry, 

 and scaly ; the belly is tucked up and the back arched ; there is occa- 

 sional diarrhoea and vomiting, and, when the worms are numerous, 

 convulsions or fits. Treatment. — The medicines named for worms 

 in the dog (pay. 277) can be given in a little milk, or the powders 

 can be mixed in castor oil and milk and administered by the aid of 

 a clog with a wooden sole, or a strong shoe with a hole cut in the 

 leather at the toe (Plate LIV., No. 3). Press the clog into the 

 mouth of the pig and pour the medicine inside, when it will be 

 swallowed without the danger of choking. Daily doses of one to 

 two teaspoonfuls of flowers of sulphur answer well for worms, w r hile 

 turpentine in doses varying from 1 teaspoonful to 1 tablespoonful 

 mixed with oil and milk, or beaten up with an egg and given as 

 described above, also has a good effect. 



284. Protrusion or Eversion of the Rectum is sometimes met 

 with in young pigs, but most frequently in sows after parturition. 

 When seen, the parts must be thoroughly washed with tepid water 

 and Sanitas, smeared with extract of belladonna, and returned, and 

 then kept in its place by stitches of tape put across the opening. 



285. Imperforate Anus. — Calves, lambs, and pigs are occa- 

 sionally born with the end of the bowel covered up, and blinded by 

 a continuation of the skin over the opening. On manipulating with 

 the fingers, the hard faeces are felt underneath. It is very easy with 

 a sharp knife to cut through the skin into the canal, and to dress 

 the wound daily with antiseptic mixture (par. 1060, No. III.), until 

 the parts are healed, when the animal, as a rule, generally does well.
