Abstract
Effects of three rearing conditions on the lying behaviour of heifers during integration into the dairy herd and their performance during the first lactation were investigated: (1) free, (2) half-day (6:45 a.m. - 06:00 p.m.) or (3) no mother-contact during the first nine weeks of life. ‘Free'- (n=5) and ‘Half'-calves (n=5) were kept in groups consisting of 13 or 11 mother-calf pairs, respectively, in the cows' barn and were suckled. Calves without mother-contact were separated after birth, grouped with other calves at two weeks of age and were fed with max. 2x3 L warm whole milk per day with a nipple bucket (‘No': n=9). During the 10th week of life mother-contact calves were separated from the dam with visual contact and were trained to drink milk from a nipple bucket. After this week all calves were grouped together and rearing conditions were the same with gradual weaning until the 13th week of life. Grown up heifers were introduced into the dairy herd (61-90 cows) in the evening 2-3 milkings after their calving, mostly singly but in one ‘No' and three ‘Free' heifers as pairs. Apart from two "No" heifers all animals had pasture access during regrouping. Lying behavior was recorded with data loggers during the first 48 h. Thereafter body weight, height at the withers and trunk girth were measured. Age at calving, milk yield until the 100th day of lactation, mean daily milk yield of the total lactation, lactation duration and culling rates were taken from the milk recording data. No significant differences between ‘Free'- and ‘Half'-heifers could be found in any parameter. On the first day after introduction heifers of all groups showed considerably reduced lying durations. In the second 24 h ‘Free'- lay significantly, ‘Half'- in tendency longer than ‘No'-heifers, based on more lying bouts. Within the ‘Free'- and ‘Half'-groups lying duration increased through more frequent lying bouts from the first to the second day. Lying duration of ‘No'-animals increased only slightly, and non-significantly, due to a significant increase of lying bout durations. No advantages in growth and productivity could be detected.
