Professional & scientific writing on modern dairy.
Bouvera Dairy Digest is a working journal of dairy practice — reviewing evidence, sharing on-farm protocols and translating research into decisions herd managers can act on.
Lying time as the master welfare signal: what 12 hours really means
Lying time is the single most validated behavioural indicator of dairy cow welfare. A review of thresholds, measurement pitfalls and what recent accelerometer studies add to a 20-year evidence base.
- Why 12 hours per day is a floor, not a target
- Cubicle design factors that consistently move lying time
- How to read accelerometer data without over-fitting the herd
- Distinguishing low lying time from fragmented lying bouts
Lameness prevention: from prevalence audits to a functional-trimming calendar
Herd-level lameness above 20% is a system failure, not a hoof problem. Combining Sprecher-style locomotion scoring with modern claw-lesion epidemiology to build a preventive trimming schedule that actually holds.
Heat stress is now a Northern European welfare problem
The THI-68 threshold sits well below the summer conditions Scandinavian and UK barns were designed for. Retrofit priorities that convert cooling spend into welfare and yield.
Cow-calf contact systems: what the evidence base actually says in 2026
Extended cow-calf contact has moved from a fringe question to an active research programme. What the current literature supports, what remains contested, and what the practical trade-offs look like in commercial herds.
Pain management for disbudding: the current standard of care
Cornual nerve block plus NSAID plus sedation is now the evidence-based baseline for calf disbudding. A summary of the drugs, timing and monitoring that make it work on-farm.
Environmental enrichment for dairy cows: beyond brushes and pasture
Mechanical brushes are now standard, but the enrichment literature has moved well beyond them. What the current evidence supports for cows, heifers and calves in intensive systems.
Calf bedding: the underrated determinant of pre-weaning welfare
Nesting score, dryness and thermal insulation drive calf morbidity more than most other pen-level factors. What the evidence supports for bedding type, depth and management.
The economics of dairy welfare: what pays back and what doesn't
Welfare investments are routinely framed as costs. The published economic literature tells a more nuanced story: several core interventions pay back within a lactation, while others require premium markets to justify.
A short history of dairy welfare science: from Brambell to sensor-based assessment
Dairy welfare science is younger than most practitioners assume. Tracing the arc from the 1965 Brambell Report through the Five Freedoms, Five Domains and modern positive-welfare frameworks.
Dairy welfare legislation: an international comparison in 2026
EU, UK, US, Canadian, New Zealand and Nordic frameworks diverge sharply on tethering, disbudding, cow-calf contact and pasture access. A practitioner's map of the current legal baseline.
