E546 The $6,600 6‑Week Weaning ‘Savings’ Trap: Why It Can Mean an $11,000 BRD and Calving Bill on a 300‑Cow Dairy

About this episode

This episode discusses the hidden costs of a 6-week weaning program on a dairy farm, revealing significant financial implications related to BRD and calving age.

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.

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…
