Management of summer feed deficits on three high-performing dairy farms in the Manawatu.

摘要

New Zealand dairy farmers can use a range of options (e.g. summer forage crops or silage) to minimize the impact of both variable and inadequate summer feed supply. Much has been written about recommended procedures for planning and monitoring pasture-based systems, but there is little documentation on the processes actually used by New Zealand dairy farmers. To this end the summer management processes of three high-performing Manawatu seasonal supply dairy farmers were studied over a period of four years. The farmers used management systems based on their experience. A range of simple techniques was used to identify potential feed deficits. The farmers then used a set of decision rules to select the best option or combination of options to overcome feed deficits. The study highlighted the potential benefits that could accrue from integrating farmer knowledge with scientific knowledge.
