## Resource

A 300-cow Wisconsin dairy thought 6-week weaning saved $6,600 a year. The real cost, once BRD and age at first calving were priced in: $11,190. This episode of The Bullvine Podcast walks through the full ledger on Dave's 300-cow herd — $55 per calf "saved" on milk replacer, erased by 24 pneumonia cases at $260 apiece, plus 60 heifers calving a month late at $82.50 each. When the math is honest, the calendar program burns cash. What You'll Learn Why 20% post-weaning BRD quietly cancels your milk-replacer savings The $252–$282 true cost of a single BRD case in the first 120 days How Quigley's 15 kg NFC threshold redefines when a calf is ready Why weaning at 42 days often leaves calves short on starter intake The intake gate that replaced the calendar: 2 lb/day for 3 days What a 10–14 day step-down does to BRD and AFC on a 300-cow herd Why This Episode Matters At replacement cow values near $3,110 per head in late 2025, every BRD case is an equity decision, not a vet bill. The ISU 2024 heifer budget pegs an extra month of rearing at roughly $82.50 per head — meaning 60 late-calving heifers quietly cost $4,950 a year. The 2024 Welk, Neave, and Jensen review of 44 studies confirms intake-based weaning outperforms fixed-age early weaning on growth and feed intake.
