Abstrakt
In robotic milking dairy systems lack of control over intakes can be problematic for
balancing the forage and concentrate portions of diets. This can lead to proble
ms associated with
high concentrate intakes and concomitant low forage intakes. To check this as a problem, the
feeding behaviour of cows was observed: the number of daily visits to the feed barrier, the
duration of these visits and actual feeding, of high
and low yielding cows. The cows were robot
-
milked and fed a ration comprising, separately, concentrate feed from a robot and a feeder, and a
grass/clover silage mix forage at the feed barrier. Individual variation in visiting times and times
spent at the
feed barrier were greater than the effect of level of production. There was no evidence
that cows with higher milk yields are differentially motivated to feed from forage. But more
dominant cows spent more time feeding than submissive cows.
