Ai i ik Treatment of a Va< i enated Herd. 



It' the scrum is pure and potent and the vaccination is done proper- 

 ly, the treated animals will seldom mis- a feed. Usually, however, 

 the serum treatment causes a slighl febrile reaction and the tempera- 

 ture may vary several degrees from normal for a period of days, some- 

 times going to 105 degrees or even higher. Within from six to ten 

 days the animal should return to normal conditions, with temperature 

 at about 103 degrees. 



If a hog becomes noticeably sick after vaccination the chances are 

 that either an insufficient dose of serum has been given, or the potency 

 of the serum is not as high as it should he. Avoid turning hogs into 

 muddy, dirty or filthy lots after they are injected. The very worst 

 place to vaccinate hogs is in the barn and the most dangerous place 

 to turn them after they are treated is in a barn yard where they have 

 access to manure. Tf they are not kept away from filth and manure 

 the losses from tetanus ("lock jaw") and septicaemia ("blood poison" ) 

 is likely to he heavy. Rest to turn them out to pasture. Tf abscesses 

 form, it indicates that the proper cleanliness and care has not been 

 exercised in the work. When abscesses do form they should be lanced 

 and the wound washed once daily with one tablespoonful lysol to one 

 quart of warm water. 



Causes of Failures From Serum Treatment. 



The few failures or unfavorable results which have been reported 

 may be attributed to one of the following three causes: 



(a) Underestimating the weight of hogs. 



(b ) Treating sick hogs with well hog doses. 



(c) Treating chronic cholera. 



Whenever you underestimate the weight of a hog you fail to give 

 a sufficientlv large dose of serum to protect him from the virus ad- 

 ministered. Here T desire to re-emphasize what has been stated many 

 times before. Give enough scrum. Don't cut the dose down to c.c. 

 in order to save 15 cents, for in so doing you may be killing a hog 

 worth S_'5. Don't treat sick hogs with well hog doses. Sick hogs 

 require double doses. The only way to determine the fact of sick- 

 ness i- to take temperature-. If temperature is over 104 the hog is 



already infected. Into such a hog you are supposed to put a double 



dose of serum and no virus. To those showing a temperature of less 

 than 104 degrees give the simultaneous treatment. There is nothing 

 quite SO important in vaccinating hogs as taking temperatures. Ybu 



may expeel to lose from 25 to 35 per cent of sick hogs treated even 



—55—
