Summary:

Danish Friesian cows in their first, second, or third lactation (early or late lactation), and some dry cows were divided between the age groups and scored for rising behaviour while in tie-stalls three times per day for five consecutive days. Scoring occurred at 11:30 h, 15:00 h, and 17:30 h. The cows were encouraged to rise using increasing levels of encouragement while minimizing the amount of force used. Scores for rising were between 1 and 5, with 1 meaning the cow rose normally and smoothly, and 5 meaning the cow rose front first. The level of encouragement required was also scored. Video recording of behaviour was recorded to assess total lying time, lying frequency, maximum lying bout length, time to lie down, time for preparatory phase of lying, time to rise and time for final phase of rising. Video records of rising were also scored. The stage of lactation affected total lying time, number of lying bouts, maximum bout length and rising behaviour while lactation number had a minimal effect on lying behaviour. Using the proposed score for rising reliably showed whether cows in tie-stalls had difficulty rising when at least 3 observations were included. The proportion of cows in different stages of lactation and of different parities should be included in assessments of rising behaviour because the stage of lactation and parity significantly affected rising behaviour.
