1
Number of farms.
2
Mean ± standard deviation per cow*year (kg).
3
Statistical analysis: MA = multivariable analysis (in the case of univariable pre‐selection of factors only effects of the final models were considered).
4
Milk delivered per cow*year.
5
Risk decreased with ø daily milk yield > 35 L and increased with < 25 L compared to 25–35 L.
