Description
The effect of two stocking rates of 5 (L) and 7 (H) heads of lactating dairy cows per hectare on herbage utilization and milk production were determined under a time-restricted grazing during 2 years from 1993 to 1994. The annual herbage utilization and milk production from pasture in 1993 were lower in H than L (herbage, 7.9 vs. 9.1tDM/ ha; milk, 8.1 vs. 9.6t/ha) since the days of grazing cycle was considerably shorter in H than L (7.8 vs. 17.1days). As a result of changing the expected daily herbage intake per head of H seasonally in 1994, the annual herbage utilization and milk production from pasture were higher in H than L (herbage, 9.9 vs. 9.6tDM/ha; milk, 12.1 vs. 10.5t/ha) even if the stocking rate of H was higher than L.
