Description
Limits to pasture and animal production from perennial ryegrass (Lolium perenne) and white clover (Trifolium repens) pastures have been studied in systems experiments with fattening dairy beef bulls in the lowland Manawatu region of New Zealand. At high stocking rates the management system utilizes peak spring pasture growth and provides sufficient herbage for animals during periods of low growth in self contained, no conservation farmlets. High animal production of approximately 1000 kg of carcass meat/ha annually has been achieved. Accumulation of pasture reserves in autumn through long rotations and reductions in grazing pressure in summer through slaughter of fattened animals are important features. Pasture growth rates in both summer and winter are considered to limit animal production and strategies for overcoming them have been evaluated. Nitrogen fertiliser applied at 100 kg/ha annually in two applications to increase late winter and spring growth rates increased pasture and animal production by 7-8% annually. Gains of up to 13% in animal production attributable largely to the growth of red clover in summer and autumn have been achieved. Higher summer and autumn growth rates from irrigated ryegrass-white clover pastures have increased animal production by 7-8% annually.
