Description

The purpose of this research was to determine milk productivity from pasture, using dairy cows of higher performance (>7500 kg for a 305-day lactation) in an intensive grazing system. In both 1993 and 1994 two groups of 3 cows each were grazed from spring to autumn: one group in 1.1 ha (LS) and the other group in 0.65 ha (HS) pasture. A different part of each pasture was cut for hay or silage twice a year. Concentrate and roughage were supplied according to the nutrient requirement of the cows. Milk production from grazed and harvested herbage of the LS pasture in 1993 and 1994 was 10,509 kg/ha and 8,766 kg/ha, respectively, and that of the HS pasture was 9,918 kg/ha and 12,025 kg/ha, respectively, for the same 2 years. The cattle’s energy intake from the LS pasture was 80 % of their total intake, and 50-60 % of their total intake from the HS pasture.
