It was most important that owners should realise the danger of disease in stock, the Chief Veterinary Surgeon (Mr. Max Henry) stated today when he opened the 17th annual conference of the Institute of Stock Inspectors, at the School of Arts, City.
Past experience showed how vital it was that disease should not be allowed to spread, Mr. Henry continued, and he instanced an outbreak of pleuro-pneumonla, which swept through Victoria, spread to the northern Queensland cattle industry, and left behind a dreadful trail of dead beasts.
"We must make the stockowner understand that a beast allowed to recover from pleuro-pneumonia is a potential menace for the rest of its life," he said.
One of the problems of last year was the discovery of sheep infested with true cattle tick, said Mr. Henry.
The sheep concerned were not in N.S.W., but since infestation had occurred elsewhere, it was possible to occur here.
After two dippings, several thousand sheep had been removed from the affected areas. Johnes' disease was also a problem in 1935 he said. If it could be proved definitely that the disease existed in N.S.W. and it could be located, future heavy economic loss might be saved the State. Two authentic cases were on record locally, both in newly imported cattle. Fortunately the cattle had been kept isolated.
Dealing with tuberculosis, Mr. Henry said the problem was to find means of doing effective work with the staff now available.
The chairman (Mr. W. J. Smith Young) congratulated Mr. Henry on his efforts in combating pleuro-pneumonia. Today it was practically unknown, which was in contrast to the position 20 years ago. It was a wonderful record, and there was now little fear of any disease getting out of control.
