Episode Details

Waiting six hours to feed colostrum caps roughly a quarter of your show heifer's disease protection. The class was decided at 2 a.m. in January, not at the clipping chute in September.

The Bullvine Podcast takes apart the research on why the 28% IgG loss is an absorption efficiency problem, not a colostrum quality problem — plus the hay belly trap, the Jersey-on-Holstein ration mistake, and the Ferrari problem with genomic Feed Efficiency scores. Every threshold, every decision, every trade-off a working breeder needs before next show season.

What You'll Learn

• Why colostrum absorption collapses by hour six, even when quality stays intact
• The Brix and serum IgG thresholds the 2020 Lombard consensus actually requires
• How uNDF240 creates hay belly before your grain program can work
• Why Jerseys on Holstein rations freshen with mushy udders
• What a high Feed Efficiency RBV means for your show prospect's BCS
• The 30-day move with your herd vet that tells you if your program works

Elite embryos at the tier of Sale of Stars, Sale of the Century, and All Canadian Classic trade in the low to mid four figures, with recipient conception around 30 to 40 percent. That's high four to low five figures per live calf on the ground — before starter, before fitting. Losing 28% of her immunity because you slept through her birth isn't a protocol detail. It's the single highest-leverage decision in the whole development program.
