Methods of Vaccinating. 



Two methods of vaccinating are in vogue, viz. : serum alone, and 

 simultaneous method. The scrum alone method means injection of 

 serum without virus. This method only affords temporary immunity — 

 three to six weeks. We do not advocate or even indorse this method 

 as the immunity does not last long enough to justify the expense. 



The simultaneous method consists in the injection of a small amount 

 of virus at same time serum is injected. This method affords life 

 immunity and does not cost one cent more and does not require one 

 minute additional time than the serum alone method. This simul- 

 taneous method has our unqualified indorsement and is the only one 

 we advocate. 



Time to Vaccinate. 



The proper time to vaccinate hogs is before they become sick. If 

 you wait until they are standing around with ears drooping, backs 

 arched, noses to the ground, no appetite, hind legs partly paralyzed 

 and temperature above 105, it is certainly too late to save all of them 

 and oftentimes the majority will succumb even in spite of serum treat- 

 ment administered in double doses. 



Vaccinating Suckling Pigs. 



The protection of young pigs from cholera is the "knottiest prob- 

 lem" which the department has been called upon to solve; however. 

 from our own experience and the experience of others, we are con- 

 strained to summarize the young pig problem as follows: 



We know that suckling pigs are extremely SUSCentible to hog 

 cholera and that when they contract it the death rate (mortality) is 

 very high- oftentimes [00 per cent of them die. 



We know that it is impossible by any known method of vaccina- 

 tion to gel life immunity in ;in\ large per cent nf suckling pigs.
