Episode 30: PCOS Round Table

-Full video episode available on YouTube-

What started as scattered observations across different herds slowly turned into a much bigger conversation.

In this episode, Patrick Powers sits down with John Atkinson of Cashmere Cattle, Grant Vassberg of Kallion Farms, and Dr. David Rainosek to discuss fertility, hormonal balance, embryo production, and a growing theory surrounding possible PCOS like patterns in cattle, recently updated in human medicine terminology to PMOS.

The discussion explores why some naturally fertile cows consistently show lower egg counts but higher embryo development and pregnancy rates, while some high follicle count donors struggle with long term reproductive consistency.

Along the way, the group discusses selection pressure, weaning weights, embryo transfer economics, observational cattle knowledge, and the growing disconnect between what producers are quietly seeing in the field and what modern systems currently prioritize.

This is not presented as settled science or final conclusion.

It is an open discussion built around real world observations, existing research, and a belief that difficult questions deserve honest conversation.
