REl'ORT OF ASSISTANT VETERIXARIAN. 



Honolulu, June 4, 1913. 

 Dr. \'. A. X'org-aarrl. Chief of Division of Animal Industry. 



Sir: — I hereby submit the followinj:!^ report for the month of 

 May, 1913: 



Tuberculosis Control. 



No testing has been done this past month due to the lack of 

 transportation and an assistant. The services of Mr. Joseph 

 Richards, one time City and County Milk Inspector, have been 

 obtained for this Division by the Board of Commissioners, and 

 in a day or two the necessary repairs to the machine will be com- 

 pleted when we can again start on this important work. The 

 test this year, which is the fourth general test of the dairies in 

 the City and County, should total close to 6,000 head of cattle. 



Hog Cholera. 



Several outbreaks of Hog Cholera have occurred during the 

 past month in which the disease has assumed a greater virulence 

 than has been experienced before in this Territory, and the re- 

 sultant loss has been very heavy in some districts. Until recently 

 Hog Cholera has never taken a prominent place in the list of 

 diseases affecting live stock in this Territory. Assuming a very 

 mild type it has been easily controlled by strict sanitation and pro- 

 phylactic measures in the diet and care of the animals. Now, 

 however, such measures seem to be of little avail and in order to 

 control and entirely eradicate this disease an entirely different 

 line of treatment has been inaugurated. 



The treatment now being followed consists of subcutaneous in- 

 jections of anti-hog cholera serum. This produces a passive im- 

 munity lasting from five to six months and enables the animals to 

 successfully pass through an outbreak of the disease. We feel 

 confident that we can by this means materially reduce the losses 

 from this disease and keep it under control. 



On the 22nd of May a valualile herd of twenty-seven (27) 

 hogs owned by the College of Hawaii were given subcutaneous 

 injections of anti-hog cholera serum varying in amounts from 10 

 to 50 cc. according to the size of the animals. A short time before 

 the treatment was applied it had been rejiortcd at this oftice that 

 liog cholera had broken out in this herd with the loss of two ani- 

 mals. Serum was immediately cabled for and upon arrival the 

 remaining animals were at once treated. Since then no deaths 

 have occurred and temporary immunity to the disease has boon 

 established. 



Great care is necessary to prevent abscess formation at the j^oint 

 of injection. Thorough disinfection and clean surface are abso- 

 lute rcquirenvnts ; 5 i)er cent. carl)'»lic acid or a strong solution
