1 V Y . ' _ . 1 ini ** E p t The Prevention of Hog Cholera. 75 I c 1 1 ` j In administering serum, the hogs to be treated should be g . I penned up the night before and handled as quietly and ,,;?_ _~ _,iL {Y expeditiously as possible, and all instruments used in the . 'p.ei rp-- _ inoculation should be thoroughly sterilized by boiling in V water immediately before the injection or administration. . _ Hog cholera serum is administered with a hypodermic syringe and needle into the muscle of the hog. A conven- ient site is the muscles of the inside of the ham. Hogs too large to throw are snubbed to a post with a rope around a'-;- the upper jaw, and serum injected into the muscles of the neck just_ behind the ear or back of the jaw. It is not con- venient to draw the serum from the bottle into the syringe, " and a sterile container must be used. A covered porcelain H cup or a tumbler with a saucer for a cover will suffice. The container as well as the syringe must be thoroughly boiled or washed in a strong disinfectant before using. Before making the injection the skin at the site of injection must _ be washed with disinfectant. A 3 per cent. compound solu- i . tion of cresol or any of the reliable coal tar dips may be used. in , Body temperatures are taken to detect animals infected at g - time of inoculation. Such animals may sometimes be saved F, by administering double the usual quantity of serum, but ji uniform results must not be expected in infected herds. l Serum is preventive and not curative. Hogs may be given fp the single treatment at any age, the dose of serum depend- - L ing on the weight of the animal. A Dose Table. l- _ 10 c c. up to 10 lbs, in weight. 15 " for all sizes between 10 and 20 lbs. 20 " for all sizes between 20 and 50 lbs. 30 " for 75 lbs. or more than 50 lbs. 40 " for 100 lbs. or more than 75 lbs. _ p i 50 " for 150 lbs. br more than 100 lbs. 60 " for 200 lbs. or more than 150 lbs. 4 _ A 70 " for 250 lbs. or more than 200 lbs. i 80 " for 300 lbs. or more than 250 lbs. . 90 " for 400 lbs. or more than 300 lbs. `Y l 100 " for more than 400 lbs.
