Further housing hazards | Wider feeding alley | ↓ | Sarjokari et al. (2013), Westin et al. (2016b) |
Higher cow: cubicle ratio | ↓ | Gieseke et al. (2020) |
↑ = significant increase in prevalence of lameness (p < 0.05), ↓ = significant decrease in prevalence.
Only in primiparous cows.
Only during second lactation (effect of treatment*lactation).
Mastic asphalt is a mixture of crushed stone gravel and bitumen (slip‐resistant but abrasive), partially‐floored mastic asphalt: 55–66% mastic asphalt, 33–45% rubber or plain concrete.
