Field notes on this focus

1. Note 01Camera scores are screening — not diagnosesComputer-vision gait scores can prioritize cows and track herd trends — useful screening when camera setup is honest, never a veterinary diagnosis on their own.Knowledge level in this topic: Intermediate.

2. Note 02Early Lameness Detection: Why Treating the First Lame Step MattersCatching the first mild limp beats waiting for an obvious non-weight-bearing cow. Early follow-up shortens lesion progression and protects lying time and milk.Knowledge level in this topic: Intermediate.

3. Note 03Digital Cushion Thickness, Transition, and Sole-Ulcer RiskThe digital cushion helps dissipate load beneath the pedal bone. Thin sole soft tissues have been associated with later claw-horn lesions, but cushion thickness is not simply a reflection of body condition. Stage of lactation, parity, farm conditions, previous lesions, and tissue structure all appear to matter.Knowledge level in this topic: Advanced.
