Hypothesis
What is the prevalence of neonatal infectious arthritis and the associated farm management practices on UK sheep farms?
Conclusion
The study found a 64% prevalence of neonatal infectious arthritis among UK sheep farms, with various management practices influencing its occurrence.
Supporting Evidence
- 64% of farmers reported cases of joint ill in the 2020 lambing period.
- The median incidence of joint ill was 1.4% of lambs born.
- Prophylactic antibiotic use was associated with a reduced risk of joint ill in outdoor flocks.
- Farmers reported a median of 8.5 cases of joint ill per farm.
- Only 5% of farmers had the bacterial cause of joint ill diagnosed by a vet.
Takeaway
This study looked at how many lambs got sick with joint problems and what farmers do to try to stop it. They found that many farms had sick lambs, even when they tried to prevent it.
Methodology
An online questionnaire was distributed to UK sheep farmers, collecting data on prevalence, management practices, and risk factors associated with neonatal infectious arthritis.
Potential Biases
Responses may reflect social desirability bias, as farmers might report practices they believe are correct.
Limitations
The study may be affected by reporting bias, as farmers with NIA outbreaks may be more likely to respond.
Participant Demographics
322 farmers from 69 UK counties, with a mix of lowland, upland, and mountain farms.
