Abstract Sensors can measure various types of behaviour automatically in a dairy herd. They can,therefore, be used to monitor a herd and the computer can detect deviations of normalbehaviour and give an attention to the farmer. In order to do so, normal baseline values areneeded. Since these may vary due to parity and housing conditions, the aim of this study wasto investigate the effects of parity and freestall bedding (cow matrass vs deep litter) on dailylying time, locomotion, standing and eating time from 42d a.p. – 28d p.p. Sixteen Dutch dairyfarms (3,158 cows) were used in this study and the number of steps per day, time of standingand lying (in sec/2 h period)and time eating (in sec/2 h) were collected by means of Nedapsmart tags (Groenlo, the Netherlands). Furthermore, in the first two weeks post-partum bloodsamples were collected to measure BHB levels. T-tests and timeseries were used for comparison.The results of locomotion revealed that primiparous cows made 833 (SD 132; P<0.001) moresteps on daily basis in comparison with multiparous cows. Animals housed on cow matrassesmade on daily basis on average 621 (SD 30; P<0.001) more steps vs animals in stalls with deeplitter bedding. Primiparous cows spent daily on average 64 minutes (SD 4.8; P<0.001) less timelying down and animals on farms with cow matrasses lie on daily basis around 30 (SD 17.3;P<0.001) minutes less when compared with animals housed on farms with deep litter bedding.The number of lying bouts increased from 6 to 9 per day 1 day before calving and decreased to7 per day after calving. The time lying per day decreased before calving. And the average lyingtime increases again in the first week post-partum. Cows that had a subclinical ketosis postpartumwere eating half an hour less during the dry period. Already 42 days before calving thisdifference could be observed. It became clear that with sensors differences in behaviour duringthe dry period can be detected that could lead to managerial interventions to reduce the riskfor diseases post-partum. This study is ongoing and more data will be obtained.
