Abstract

Legislation in Sweden and Norway requires that dairy cattle have outdoor access in summertime. Pasture utilization can be challenging with high yielding cattle and large herd-sizes. Therefore, many farmers choose to offer their cows access to an exercise- and recreation area only, rather than a full production pasture. However, is an exercise paddock as attractive as production pasture for the cow? We compared part-time production and exercise grazing in an automated milking system, with outdoor access in the morning (4.5 h) and the evening (4 h). The production pasture group (P) was offered fresh production pasture daily (≥15 kg dry matter (DM) cow-1) and given a limited silage ration (6 kg DM) night-time. The exercise pasture group (E) was given access to a small exercise paddock (<1 kg DM cow-1) and were fed silage ad libitum 24 hours. Milk yield did not differ significantly: 36.1 kg for P and 36.0 kg for E. However, behaviour differed (P<0.0001), with 5.5 (P) and 2.6 h (E) spent outdoors, and 3.7 (P) and 0.6 h (E) grazing time. In conclusion, while milk-yields were similar between the groups, lower amounts of supplementary feed were needed for cows on treatment P, who also spent longer hours outdoors and grazing.
