Abstract
The effects of herbage mass at closing (CHM) and closing date (CD) in autumn on spring herbage mass (SHM) were investigated on 10 dairy farms over a 2-year period. SHM was regressed on CHM and CD. CD had significant (P < 0.001) effect on SHM. Each 1-day delay in closing from 1 October to 11 December reduced SHM by 15.0 kg dry matter (DM)/ha. The effect of CHM varied significantly with farm x year combination. Exponential herbage accumulation curves were fitted to the data to describe the accumulation of herbage from closing in the autumn to final measurement in spring. These models had a r.s.d. of 367 and 320 kg DM/ha for Year 1 and 2, respectively.
