Abstract

The objective of this study was to test the effect of two different pasture allocation frequencies (1 vs 7 days) on milk production of grazing dairy cows. Ten lactating Holstein cows were randomly assigned to the treatments in a 2×2 Latin square design with two 7-day periods repeated three times (autumn-winter, early and late spring). During autumn-winter all the cows had one grazing session and were supplemented with 10 kg DM of a mixed ration. In spring, the cows were not supplemented and were removed from the pasture only for milking. The pasture used was a mix of Festuca arundinacea, Lotus corniculatus and Trifolium repens. Neither milk production (27.0±2.38, 20.8±0.69 and 14.7±0.66 kg cow–1 day –1), post-grazing sward heights (10.6±0.23, 11.9±0.83 and 16.3±1.37 cm), nor daily grazing time (196±10, 535±22 and 592±14 min cow –1 day –1) were different between treatments in autumn-winter, early spring, and late spring, respectively. This finding opens a viable option for farmers to simplify daily management and reduce labour demands.
