1Activity and rumination were recorded by HR-LD Tag (SCR Engineers Ltd) with a 3-axis accelerometer and a microphone.
2Herd = organic or conventional; Month = January to December; Year = 2014 to 2017; Breed group = contemporary Holstein, 1964 Holstein, crossbreds sired by Montbéliarde, Viking Red, Holstein, Normande and Jersey; Parity group = primiparous or multiparous.
