Table 1.

Daily behavioural patterns (mean, SD and range (minimum and maximum)) for each of the three groups (29 cows each) managed on a single farm over the experimental period of 13 d. Grazing, ruminating and lying times were measured using accelerometers attached to each cow (data from 29 cows/group). There were no differences in the duration (p > 0.1) between the groups for any of the behaviours.

Variable	Mean	SD	Range
Grazing time (h/d)
Group 1	7.5	1.4	4.1–10.0
Group 2	7.7	1.3	3.8–9.6
Group 3	7.6	1.8	3.8–10.1
Ruminating time (h/d)
Group 1	8.2	0.8	6.7–9.4
Group 2	8.4	0.7	7.1–9.8
Group 3	8.1	0.7	7.0–9.3
Lying time (h/d)
Group 1	9.0	0.8	7.2–10.1
Group 2	8.8	0.9	6.9–11.8
Group 3	8.9	1.0	7.4–11.5
