Description
In much of Buenos Aires Province, Argentina 60% of the year’s pasture production occurs during spring. This trial was carried out to test the minimum area necessary for grazing in the period of maximum pasture growth in the 3 to 4 months of spring, so that in turn the maximum potential area for forage conservation could be estimated. At the two levels of herbage allowance aimed for (achieving 18.1 and 36.6 kgDM/cow/d), herbage intake was 11.1 and 13.4 kgDM/cow/d and milk production 20.9 and 22.3 l/cow/d respectively. While these differences were not significant, the trial demonstrated a potential of 70 % of pasture area could be available for forage conservation in a normal spring, which compares with 5 to 15 % with some of the best milk producers.
