A variety of on-farm tests for the assessment of the human-animal relationship were evaluated. At the herd level, cows were tested in a voluntary animal approach (VAA) test, where the number of cows and their latencies to interact with a stationary human was recorded. The reactions of cows to an approaching person were also recorded during the avoidance (AV) test. In the first study, both tests were conducted on the same day on 12 commercial dairy farms, with two people recording responses simultaneously. The cows were tested with both familiar and unfamiliar people. The inter-observer reliability was high for both tests. The shortest latency for touching the unfamiliar test person was found on the first test day. There was high test-retest reliability for the AV test, and no effect of familiarity of test person was found. The objective of a second study was to determine the correlation between the two behavioural tests. On ten commercial dairy farms with loose housing cubicle systems, both behavioural tests were conducted on the same day at four different times. There was a high correlation found for the VAA and AV tests at herd level. The human-animal relationship at the herd level can be evaluated on-farm using the AV test. The motivation for the animal’s approach behaviour during the VAA test was not as clear.
