In the upper picture the pigs are treating themselves. Below are shown hogs which died during shipment to market.] Avoid any breaking of the healing tissue and do not have the washing solution too strong, else it may injure the delicate tissue growth. A teaspoonful of carbolic acid to a quart of water is strong enough. With lacerated wounds the treatment is very similar. If the wound goes bad and becomes spongy add a tablespoonful of acetate of lead and a tablespoonful of sulphate of zinc to the antiseptic solution and apply twice daily. [Illustration: MAKING POST MORTEM EXAMINATIONS The upper right hand picture shows the intestines of a healthy sheep. On the left nodule disease is discovered. The bottom picture illustrates how a carcass may be opened for the examination.] =Nail Punctures.=--These very frequently cause trouble. You have no way of observing the wound and your only way of judging is from the way the animal walks or acts, and if the hoof is unduly hot. Locating lameness in the stifle joint is a common but inexcusable error, as the action resulting from lameness in the two parts is entirely different. The so-called gravel which is said to enter the sole of the foot and then to work out at the heel is usually the working out of the pus or the matter resulting from a nail puncture or a bruise. If an animal becomes suddenly and severely lame and there be no evidence of any injury to any other part of the leg, such as swelling, heat and pain upon pressure, it is always well to look for puncture in the foot. If the animal stands with the lame foot extended and when walking places the lame foot well forward and brings the well foot up to it, the evidence of puncture is still stronger. To examine the foot properly the shoe should be removed. It is not sufficient to merely scrape the bottom of the foot clean, for if the nail has pulled out and the horn sprung back in position, all trace of its entrance may have been obliterated. To examine the foot properly, tap the hoof with a hammer or knife and the exact spot may be definitely located. If the injury is of a few days’ standing, additional heat in the hoof and, perhaps, slight swelling of the coronet may also be present. In treating such wounds, pare away only such parts of the hoof as necessity requires and introduce a bit of cotton cloth rolled as a string by means of a probe of some kind. Both probe and cotton must be treated with the antiseptic solution. This solution should be a little stronger than for flesh wounds. Make the solution by using a teaspoonful of carbolic acid to only a pint of water. After the cotton has been inserted a few times and withdrawn, each time a fresh cord being used and fully saturated, leave the last one in for a few hours and then repeat the treatment. This should be done three or four times each day.
