REPORT OF THE COLONIAL VETERINARY SURGEON, HONG KONG,
FOR THE YEAR 1939.
Section I.
(a) Owing to the persistence of unsettled conditions it is very difficult to tell at present whether or not the live stock industry of the Colony is increasing. At the moment, owing to the recent military activity in the adjacent Chinese territory the amount of live stock in the Colony is larger than before but it is not yet possible to tell how much of the increase will remain.
(b) The position as regards animal health remains very satisfactory.
Section II.
(a) Disease Control.
Control of importation and movement still prove effective.
CONTAGIOUS ABORTION.
The position is not serious and continues to improve. Segregation of infected animals and the rearing of all calves on milk from non-aborting cows is still carried on.
Anthrax. Two cases occurred among ponies in a stable near the frontier.
Three cases occurred in cattle sheds on the island. All were isolated cases.
Rabies. No case occurred throughout the year. Control of movement and muzzling was continued.
The following animals were kept under observation during the year on account of being suspected of being rabid but all were found free from the disease:-
Cats 2.
Dogs 305.
Monkeys 1.
7 brains were examined by the Government Bacteriologist but no Negri bodies could be demonstrated.
Rinderpest. One small outbreak occurred in a group of cattle sheds on the mainland among cattle which had been immunised by the serum simultaneous method. The virulence of the infection seemed to be high but the power of spread very low, cases occurring singly and at comparatively long intervals. Fifty animals were affected and 22 died.
TUBERCULOSIS.
Tuberculin testing by the majority of owners is still carried out and reactors are isolated from the rest of the herd. Reactors which are poor milkers, infected with B. Abortus or showing any abnormality of the udder, are slaughtered. Calves from reacting cows are removed at birth and reared on milk from healthy cows.
All milk sold in the Colony is pasteurised.
A few cases of infection of the neck glands are found in swine.
