 DIVISION OF ANIMAL INDUSTRY. 



REPORT or THE TERRITORIAL VETERINARIAN, 

 FEBRUARY, 1921. 



Honolulu, March 15, 1921. 



Board of Commissioners of Agriculture and Forestry, Honolulu, T. H. 



Gentlemen: — I have the honor to submit the following report on the work 

 of the Division for the month of February : 



TUBERCULOSIS CONTROL. 



During the past month a total of 516 head of cattle were tuberculin tested 

 of which number 5 head w'ere condemned, branded and slaughtered, positive 

 lesious of tuberculosis being found in each case. 



SWINE PLAGUE. 



On February 15 I was called by Dr. W. T. Monsarrat to investigate and 

 diagnose an outbreak of disease among swine at the Alexander Young Farm, 

 Kalihi. 



Upon arrival I found one hog dead — or dying — which I had killed for 

 diagnostic purposes, and two showing symptoms of commencing sickness. 



The post-mortem examination of two carcasses revealed hemorrhagic septi- 

 cemia with commencing intestinal complications in one case. Vaccination of 

 the remaining animals about tw^o hundred head with mixed infection vaccine ; 

 the administration of necro bacillosis powder in the feed and thorough clean- 

 ing and disinfection of the premises was advised. The recommendations 

 were carried out in a very efficient manner by Dr. Monsarrat with the result 

 that the total loss was confined to the two animals dead at the beginning of 

 the outbreak. 



HEMORRHAGIC SEPTICEMIA OF CATTLE. 



At the request of Mr. George Gibb, manager of Hutchinson Sugar Plant. 

 Co., I left on the S. S. Mauna Kea for Naalehu, Kau, Hawaii taking with 

 me 1750 doses of vaccine and serum for the revaccination of the Kaalualu 

 ranch cattle. 



I arrived in Hilo on the morning of February 27 and left the sanie day 

 with Dr. Elliot for Naalehu and the following morning started vaccinating. 

 In all about 2600 head of cattle were vaccinated and as the supply of vac- 

 cine was practically exhausted at the time these were injected, I considered 

 it unnecessary to remain at the ranch longer and so left for Hilo en route to 

 Honolulu. 



From the time of the first vaccination in May, 1920, to the time of my 

 arrival, betAveen 100 and 150 head of cattle had been lost and revaccination 

 was deemed advisable. During my stay in Hawaii no cattle were reported 

 lost either on the ranch or on the various homesteads. Since my return Mr. 

 Gibb has recently reported the loss of four head with five more sick, all being 

 cattle vaccinated at the time I w-as on the ranch. 



On March 12 enough vaccine was forwarded to Dr. Elliot to inject 2600 

 head giving them double the ordinary amount. This, together with what 

 they have already had should produce as high a degree of immunity as it is 

 possible to obtain in connection with this disease. 



At best, the period of immunity following vaccination is short, conse- 

 quently revaccination will have to be practiced for some time and losses 

 among the cattle in this particular district will occur from time to time for 

 a considerable period. Animals sick from the disease or just coming down
