Description
The development of productive dairy farm systems integrating irrigated temperate pastures with rain-grown tropical pastures in subtropical Australia is described, Milk production increased from 2976-34211/cow (P<0,01) with increased temperate pasture allowance from 0. I to 0.2 ha/cow, and this increase was similar for nitrogenfertilised ryegrass or clover-ryegrass mixtures, Temperate pastures provided cows with a high protein diet (20-30% crude protein}, enabling energy-rich grain and molasses concentrates to be efficiently used, Increasing supplementation to S kg grain/cow day increased milk yields to S109 I/lactation. Nitrogen fertilisation of perennial tropical grasses enabled higher stocking rates to be used and, together with the increases in production/cow, increased farm output from 464S I/ha to 7300 I/ha.
