NEW ZEALAND DAIRY FARM SYSTEMS AND KEY ENVIRONMENTAL EFFECTS
Frontiers of Agricultural Science and Engineering 2021, Volume 8, Issue 1,
• NZ dairy farming systems are based on year-round grazing of perennial pasture (ryegrass/white clover).
• Milk production per hectare has increased by about 29% with increased use of externally-sourced feeds over the last two decades.
• Externally-sourced feeds with a low protein concentration can potentially reduce N2O emissions and N leaching per unit of production.
• Systems analysis is important for evaluating mitigations to minimize trade-offs between environmental impacts.
This paper provides an overview of the range of dairy pasture grazing systems used in New Zealand (NZ), the changes with increased inputs over time and associated key environmental effects including nitrogen (N) leaching and greenhouse gas (GHG) emissions. NZ dairy farming systems are based on year-round grazing and seasonal milk production on perennial ryegrass/clover pasture where cows are rotationally grazed in paddocks. There was an increase in stocking rate on NZ dairy farms from 2.62 cows ha−1 in 2000/2001 to 2.84 cows ha−1 in 2015/2016. During the same period annual milk solids production increased from 315 to 378 kg·yr−1 per cow. This performance has coincided with an increase in N fertilizer use (by ~ 30%) and a twofold increase in externally-sourced feeds. Externally-sourced feeds with a low protein concentration (e.g., maize silage) can increase the efficiency of N utilization and potentially reduce N losses per unit of production. Off-paddock facilities (such as standoff or feed pads) are often used to restrict grazing during very wet winter conditions. A systems analysis of contrasting dairy farms in Waikato (largest NZ dairying region) indicates that the increased input would result in an increase in per-cow milk production but little change in efficiency of milk production from a total land use perspective. This analysis also shows that the increased inputs caused an 11% decrease in N footprint (i.e., N emissions per unit of milk production) and a 2% increase in C footprint (i.e., greenhouse gas (GHG) emissions per unit of milk production).jiafa.luo@agresearch.co.nz

This paper summarizes the development of utilization models for the return of livestock and poultry manure to farmland in China. It analyzes the problems affecting the industrial development of the utilization of livestock and poultry manure recycling, and discusses development strategies for the next step in this process. In past years, important progress has been achieved in exploring utilization models for returning livestock and poultry manure to farmland, and in identifying suitable parameters for the farmland carrying capacity of livestock, both at home and abroad. However, problems remain such as unbalanced nutrients after combining planting and livestock systems, large nutrient losses, and a lack of reasonable principles for manure application on farmland. In the next step, studies should be based on the concept of the environmentally friendly return of manure to farmland and should introduce the concept of nutrient management after combining planting and livestock systems. Techniques should be carried out for the collection, storage, and processing of manure; for its return to farmland; for reasonable manure applications; for balancing nitrogen and phosphorus nutrients in order to reduce non-point source pollution; and for other aspects. In addition, policies about the efficient recycling of livestock and poultry manure should be promoted.
