ROUND WORMS.
Cause.—Is undoubtedly due to filth or hogs eating food or drinking water contaminated with well developed eggs or embryos of roundworms, thus taking them into their digestive canal, where they multiply rapidly and set up considerable irritation. This worm varies in length from three to thirteen inches, and is of a reddish-brown color.
Symptoms.—The Roundworm is generally passed with the feces, and can be readily seen with the naked eye. A hog infested with a large number of these worms is generally restless, appetite varied. When these worms develop in large numbers, they obstruct the intestines. In other cases they irritate and inflame the intestines, causing inflammation and diarrhoea, and death may be due to either obstruction or inflammation of the bowels.
Treatment.—Treatment is very satisfactory. Withhold all food from eighteen to twenty-four hours. Then place in one pint of finely ground feed, Calomel and Santonin, each five grains to every one hundred pounds of hog weight. For instance, if the hog affected with round worms weighs two hundred pounds, double the dose by giving ten grains of each of the above, but if the hog only weighs fifty pounds, give one-half the dose mentioned, or two and one-half grains of each. This treatment should be repeated in a week or ten days to assure the expulsion of worms that might have survived the first dose. Feed sparingly on laxative food, as bran mashes and vegetables, for a few days following each treatment.
RUPTURE.
(Scrotal or Inguinal)
Definition.—In the male the intestines pass through the wide Inguinal Canal, through which the cord of the testicle passes. It is not difficult to recognize this form of rupture, as the scrotum that normally retains only the testicles is usually enlarged by the bowels entering it. Sometimes the scrotum almost reaches the ground, and in this case, both sides of the scrotum, or the sack which contains the testicles, also contains intestines. If the pig is held up by the hind parts, the intestines will gravitate back into the abdominal cavity, but as soon as a pig lies down or stands they again return into the scrotum. The testicles can be located at the bottom of the enlargement.
Cause.—Hereditary tendencies predisposes them to rupture; pigs having large Inguinal Canals through which the testicle passes; by pigs being crowded, injured, squeezed at troughs, or passing through narrow doorways. Weakness and severe straining from constipation also produce rupture.
Symptoms.—An enlargement of the sack containing the testicles. Sometimes there may be a strangulation of the intestines where they fold or twist. They become inflamed and produce death. The pig dies in great pain, but fortunately, strangulated ruptures in pigs are very rare, as the scrotum and canal which the intestines occupy relax and become very roomy.
Treatment.—Operation is the only method of relieving or curing Inguinal or Scrotal Rupture. My advice is to operate as soon as possible. When the pigs are small, there is less danger. The pig to be operated on should be fasted for at least twenty-four hours, as it is easier on both the operator and the pig when the intestines are empty, or nearly so.
The operation which I have found to be very successful is as follows: Have an assistant hold the pig up by its hind legs. Prepare an antiseptic solution of Carbolic Acid five per cent, or Bichloride of Mercury, one in one-thousandths, in a pan. Have a needle threaded with a medium sized absorbent silk or cat-gut suture. Prepare a clean, sharp knife; wash the seat of operation with either antiseptic solution. Now, proceed to locate the testicle by having the hind parts elevated. The intestines must be pressed back into the abdominal cavity. The testicle will remain in the sack or scrotum; now grasp the testicle between the fingers and make the incision through the scrotum and to the lower portion. It may be necessary to insert two fingers to withdraw the testicle. When the testicle is located, withdraw it. Before cutting it off it is well to run a needle containing a thread through the last covering of the testicle so as to prevent the membrane from returning. After this is securely done, remove the testicle and sew the inner membranes that envelop the rupture and testicle with what is called a “tobacco pouch suture.” Draw it together firmly and tie and cut off suture about one-half inch from the knot. Your operation is now complete. Do not sew the outer incision in the scrotum, as it would have a tendency to accumulate dirt and hold pus. It should have a free drainage. Wash with one of the above mentioned antiseptics twice daily until thoroughly healed. Also feed laxative foods that are easily digested.
