Potential environmental effects of dairy sheep
There is little knowledge about the environmental impacts of dairy sheep. Evidence is required to support the reputation of sustainability and assess whether dairy sheep milking may be a suitable land use in nitrogen-stressed catchments.
Research was undertaken to quantify some of the potential environmental effects of dairy sheep production systems in New Zealand. The four goals were:
- Quantify nitrogen losses to water
- Estimate the intensity of nitrogen and greenhouse gas emissions
- Characterise effluent and refine good management practice guidelines
- Refine farm system models
