A SURVEY OF CATTLE PRODUCERS IN THE BOOPHILUS MICROPLUS ENDEMIC AREA OF QUEENSLAND TO DETERMINE ATTITUDES TO THE CONTROL OF AND VACCINATION AGAINST TICK FEVER

摘要

A survey by mail was used to determine the views of beef producers in the Boophilus microplus endemic area of Queensland on the control of and vaccination against tick fever, Data from 448 questionnaires were analysed, representing 2.7% of beef producers in the survey area. Producers considered buffalo fly (Haematobia irritans exigua) infestation as the most important problem whereas tick fever ranked sixth overall, Private veterinarians were regarded as the most important source of information on vaccines for cattle followed by a weekly rural newspaper. From the survey we estimate that about 33% of producers used the tick fever vaccine produced by the Tick Fever Research Centre of Queensland Department of Primary Industries but there were significant (P < 0.05) variations between regions and herds, Large herds (greater than or equal to 400 head) in south-east Queensland were the most likely to be vaccinated against tick: fever, Of the producers who did not use the vaccine, over 70% replied that there was no need to vaccinate because of the low risk of the disease in their herds. In 52% of unvaccinated herds the treatment of animals with acaricide was considered the most important means of tick fever control and 61% of these herds comprised Bos indicus x Bos taurus or Bos indicus cattle.
