Great to see these five, $3,000 awards for high school students based on creative submissions rather than grades. Topic: Agriculture and food careers and their impact on sustainability. Please RT & Share with students and schools (in Canada) - both rural and urban alike.

Keep safe around cattle, folks. A little reminder of what an aggressive cow can look like. More than protecting her calf too (which is a few months old, and not even her own - but adopted). This cow is genuinely stressed / upset, and a safety risk.

Please join us in-person at the U of Guelph, or virtually on-line, May 10. Science to understand how animals experience the world is less scary than you think. Click the link to register and to see the full schedule of talks.

Highest prices I've EVER seen on dollar calves, yesterday at the auction here in SW Ontario. Selling on choice, the group of 12 we watched had a range of $350 to $900, and averaged $530!

It sure does (IMO)! The challenge for ethologists is describing it and the affective state(s) experienced by the calf in the cart, and those watching the show. What is it about bedding?!?

Please retweet / re-X(?), share to your contacts, or send via DM to help Charlotte Winder and I get as many responses as possible to our short survey of Ontario cow-calf producers.

Culling decisions: Analyze cattle welfare, enhance the bottom line agproud.com/articles/60249…. Whether beef or dairy, could calling them "market cows" instead of "cull cows" help orient our thinking more toward financial opportunity rather than them being merely a discard?
