METHODS OF VACCINATION

MEIHODS OF NACCIN AIIUN
 There are two methods of vaccna- ton. Two materials are used in the work One is called serum. It is the material that counteracts or holds in check the cholera germs in the hog when he gets them in his system. Serum loses it's eff feet on a hog in from four to six weeks after vaccination. It is a portion of the blood of a hog that has had the cholera so severely that he cannot be made to have it again. There is some property in this blood that overcemes the cholera germ or it's effect when they come in contact Serum never causes cholera.
 "The other material which you can use at the same time yoa use the serum is called virus. Virus is blood from hog that is sick with cholera. Remember, if you bring the virus on your farm it is simply many germs of cholera condensed in small space. if in using 1t even drop is spilled put strong disinfectant on it at once or the germs may live for months and give cholera to the next crop of pigs.
 Virus is never used except when it is used with serum. A quantity of serum is injected in the neck or back of the point of the shoulder or in the flank. The germs in the virus g;y- the hog the dis ease and the serum counteracts, so that very seldom hog that is properly treat ed with good materials becomes danger OuSlV SICK, ana generally IeCoNeTS qutSNiS. This is called the simultaneous treatment Virus should never be used except by a graduate veterinarian or man who has had special training. The treatment With serum alone Is called the serum treat ment' or single treatment. When serum and virus are used at the same time 1t is called simultaneous treatment or double method.
 MUST HAVE CHOLERA
 ~l~o f i- r tha fnn hogs have been vaccinated by the si- treatment that renders them perma nently immune. It is the fact that with virulent virus gives them cholera that renders them immune. The only hog permanently immune Is one that has had the cholera.
 If you can get a good veterinarian who will be careful in his work, always employ him to vaccinate your hogs if you use virus. You can get good serum and virus from state or federal licensed firms or your agricultural college. After you to use the treatment. if you have not time to write, have your bank wire for it, giving the number of hogs you have to be treated and weights. and what kind of vaccine you want. This way you get fresh material. which is all important,
 "A perfectly healthy and vigorous hog does not take cholera nearly as readily as hog in unhealthy condition. Get rid 1T ice, whloh suck the blooa IfeiH hess' Worms also pull down the vitality of the animal. Heref is a good remedy for worms: On the 1st and 18th of each month let the hogs miss a feed, generally In the morning with hogs fed twice day, but at noon with young pigs that are fed three times day. The next feed should be slop, and with it mix turpentine as follows: For pigs weighing less than 95 pounds. one-half teaspoonful for each nig; from 25 to abfieut 40 pounds, one teasnoonful; from 40 to 100 pounds, two teaspoonfuls. and for large hogs a tablespoonful. This with the evening feed, The next morning give the same size dose of kerosene mixed with slop. This treatment Is safe if reasonable care is taken in preparing 1t. 1t is cheap and effective.
 With healthy hogs on the farm there is much less chance for the cholera germs to become effective"
