A range of forage sources and a range of cow feeding options were defined and assembled as a linear programming model to synthesize and evaluate alternative North Island dairy systems and to develop research priorities. Forage crops significantly increased production and average and .minimum income in Northland systems but had a much smaller effect on a Ruakura system. Average profitability was increased only slightly by conservation. The most rewarding research area would be to increase pasture yield. Table 1: Effects of levels of cropping and conservation on average system performance; Table 2: System responses to higher pasture yield assuming no extra cost |
