Relative perceptions of prevalence, impact and importance of photosensitisation in Australian livestock: A survey of veterinarians, livestock traders and livestock producers

AIMS: To investigate the relative differences in the perceptions and awareness of outbreaks of photosensitisation in Australian livestock stakeholders, including veterinarians, livestock traders and producers. METHODS: A questionnaire was developed and circulated to livestock veterinarians, producers and traders in Australia via email addresses obtained from public access sources. The questionnaire was designed to evaluate participants' awareness and perception of health, welfare, and production issues associated with outbreaks of photosensitisation and towards the incidence and importance of photosensitisation in livestock. RESULTS: One hundred and twenty‐eight online responses were received in total. Nearly half of the respondents (49.0%) indicated they would encounter 1–3 outbreaks annually. The majority of veterinarian and livestock producers stated that outbreaks of photosensitisation were common and economically important, with cattle and sheep being equally considered as susceptible species to this condition, and secondary (hepatogeneous) photosensitisation is the most common type. CONCLUSION: This survey confirms the anecdotal evidence that photosensitisation in livestock in Australia is commonly encountered by veterinarians and livestock producers. However, there is no industry‐wide common acceptance of the issue, broader opinions should be canvassed when considering impacts on stakeholders regarding photosensitisation outbreaks in livestock in Australia or abroad in the future.
