DIRECTIONS FOR VACCINATING. 



i. Sterilize instruments by boiling. 



2. Wash your hands. 



3. Carefully estimate weight of hog. 



4'. Restrain the hog by holding or otherwise. (See Figs. 32 



and 33.) 



5. Paint site of injection with tincture of iodine. 



6. Wash mouth of serum and virus bottles. 



7. Measure amount of serum with graduate and pour serum into 

 barrel of syringe. 



8. Replace syringe piston and cap. 



9. Fill virus syringe with required amount of virus. See label on 

 serum bottle. 



10. Inject serum behind ear or behind shoulder of one side and 

 virus on the other side. If more than one syringeful is to be used, 

 withdraw the needle and make the second injection on opposite side, 

 in which event virus should be injected into some other site. (See 

 Figs. 32 and 33.) 



Dose Table, 

 dosage simultaneous method in healthy herds. 

 5 to 15 pound pigs — 10 c.c. serum, Y\ c.c. virus. 

 15 to 25 pound pigs — 15 c.c. serum, y 2 c.c. virus. 

 2 5 to 5° pound shoats — 20 c.c. serum, Y / 2 c.c. virus. 

 50 to 75 pound shoats — 25 c.c. serum, }i c.c. virus. 

 75 to 100 pound shoats — 30 c.c. serum, }i c.c. virus. 

 100 to 125 pound hogs — 35 c.c. serum, 1 c.c. virus. 

 125 to 150 pound hogs — 40 c.c. serum, 1 c.c. virus. 

 150 to 200 pound hogs — 45 c.c. serum, i x / 2 c.c. virus. 

 200 to 250 pound hogs — 50 c.c. serum, \Y 2 c.c. virus. 

 All hogs over 250 pounds — 60 c.c. serum, i l / 2 c.c. virus. 

 The dose of serum prescribed above is the minimum amount which 

 will protect, and the virus dose prescribed is the maximum amount 

 which hogs will stand with safety. In sick herds we urgently recom- 

 mend one-third to one-half increased dose of serum, even though the 

 temperature is not elevated sufficiently to indicate actual sickness. 

 We believe by following this suggestion a much larger per cent of 

 hogs in such herds will be saved than there would had the dose not 

 been increased. 



11. After finishing a job of vaccinating all instruments and utensils 

 should be thoroughly washed and dried. The syringe pistons should 

 be lubricated with 3 in 1 Oil to prevent sticking to barrel.
