Five cows on the cull list this morning. Run the retention math at $3,010 a springer, and three of them are worth more in the stall than any heifer you could buy.

Replacement heifer inventory just hit its lowest level since 1978. That single number rewrote the keep-or-cull decision on every dairy in North America, and most herds haven't caught up. The Bullvine Podcast breaks down the retention pay-off math, the fresh-pen blind spot that corrupts it, and four fixes that don't cost a dollar of new capital.
