Insights from Hoof Health Lesion Report: Implications for Dairy Farmers

DESCRIPTION

This report by Dr. Shawn McKenna reviews data on hoof health lesions in dairy cattle from Alberta, British Columbia, and Ontario. It highlights the importance of consistent data collection as a user-friendly tool for farms, although not all herds were included in the analysis. Key findings reveal a high prevalence of Digital Dermatitis and Sole Ulcers, with significant variation between herds. The report emphasizes the need for targeted interventions on specific farms due to regional differences in hoof health challenges and the impact of environmental factors like humidity.

  1. Summary of Reported Hoof Health Lesions – What it May Mean to You Dr. Shawn McKenna

  2. Review of Tools

  3. Great data collection too • Important that the data going in is consistent • Very user friendly to collect data • Intended primarily as a farm specific tool • Not every herd has been included….so it doesn’t tell the whole picture….

  4. Alberta Dairy Hoof Health Project • Completed in December 2012 • Alberta, British Columbia and Ontario • AB – 158 farms • BC – 85 farms • Ontario – 335 farms • We have usable data on 106 herds

  5. Cows with Lesions • These would be cows that have been recorded to have significant lesions • Not all trimmers rated if cows were lame… • Not all cows had one diagnosis….

  6. Digital Dermatitis • Hairy Heel Warts • Some farms have no signs of it, but that number is low • 82% of farms have signs of HHW

  7. Sole Ulcers • Again, most farms reported to have some sole ulcers, but a small proportion of farms have severe issues

  8. Sole Hemorrhage and WLD

  9. Toe Ulcers • A lot of variation between herds • Seen very sporadically

  10. Interdigital Dermatitis / Erosions • Infected tissues at heels • Due to wet feet

  11. What does this mean? • A lot of variation between herds • Need to work specifically on your herds • In our region, we seem to have higher levels of infectious foot issues • Higher levels of humidity/moisture?

  12. Still seem to have a lot of issues with wet feet

  13. Going Forward? • Spend more time using this data within your own farm as a benchmarking tool • Encourage getting this data and showing interest will drive continuing usage
