Just 5 Minutes Of Neck Scratches Make Dairy Cows Happier, Calmer

By Shyla Cadogan

 In the dairy industry, keeping calves happy and healthy is important, especially during weaning. New research shows that a little human interaction can do the trick — particularly if it means a nice neck-scratching for the young cows.

Scientists from the University of Florida might be a welcome, cost-effective discovery for farmers. Their new study shows that socialization with other calves and humans, even if only for five minutes, can improve their well-being.

“Calves are active and seek stimulation following milk-feeding, so providing more things to do, like brushing, may calm calves, reducing sucking behaviors after feeding and increasing rest,” says Emily K. Miller-Cushon, PhD, of the University of Florida Department of Animal Sciences, in a statement.

In this episode of The Swine Nutrition Blackbelt Podcast, Cierra Kozole, PhD candidate in Swine Nutrition at the University of Guelph, explains how methionine supports lactating sows beyond milk protein synthesis. She discusses updated requirement estimates, source comparisons, methylation demand, and why modern sow genetics may require more precise amino acid strategies. Listen now on all major platforms!

"Methionine supports protein synthesis while also serving critical functions through methylation pathways that influence multiple biological processes."

Meet the guest: Cierra Kozole / cierra-kozole-772b64253 is a PhD candidate in Swine Nutrition at the University of Guelph in Canada. Her doctoral research focuses on refining estimates of methionine requirements for primiparous lactating sows, including evaluating methionine sources, nutrient partitioning, methylation reactions, and the links among amino acid supply, milk production, and sow protein retention.
