Current dairy related projects at Plant & Food Research - October 2011

  • Determine the impacts of dairying on soils by studying the efficiency of soil nitrogen use by winter feed crops, and effects of cultivation practices, simulated grazing and urine deposition on nitrate leaching under grazed forages (Pastoral 21 P-II: MSI, DairyNZ, Beef +Lamb, Fonterra).
  • Define soil physical and chemical properties that influence nitrogen transformations in grazed forage crop systems and the effects of changed land use on processes of water and N use (MSI).
  • Determine the carbon, nitrogen and water footprints of forage crops in differing winter feeding systems (MAF-SFF, SIDDC).
  • Assess the impacts of increased use of crops for supplementary feeding on dairy farms in Taranaki using split herds grazing on ‘all grass’ vs ‘grass + crop’ systems and determine the long-term effects on soil properties (MAF-SFF).
  • Develop forecasting systems around research models (APSIM ) and crop calculators  for managing irrigation and fertiliser N requirements forage cereals and brassicas (Ballance Agri-Nutrients).
  • Breeding and selection of new cereal and brassica forage cultivars with improved productivity and quality (MSI and industry).
  • Develop new opportunities for reducing the impact of insect damage in brassica crops, and improving the dispersion of biological control agents for chewing insects (MAF–SFF).
  • Develop guidelines for improving fertiliser management on West Coast hump and hollow and flipped soils as they develop following modification (MAF–SFF, Westland Milk Products).
  • Develop and evaluate AquaTrac for monitoring crop and pasture water use and for managing whole farm irrigation.

Dairy related research funded by Ravensdown / FertResearch - November 2011

  • Increasing dairy productivity (high rates of N) while not increasing N loss (multiple eco n applications). This is being investigated at LUDF and in Southland.
  • On-going development of OVERSEER Nutrient budget software (FertResearch, MAF and AgResearch)
  • All paddock testing to remove nutrient restrictions and avoid unnecessary application of unneeded nutrients. (LUDF, commercial farms)
  • Within paddock variation in soil fertility and other soil properties. (Commercial farm)
  • Investigating best timing of eco n application in relation to late summer/early autumn urine deposition. (Canterbury, Southland and as a subset in the NOMR trial series).

DairyNZ South Island Research Projects – November 2011

FEED & FARM SYSTEMS

1. MSI 20 Dairy Systems for Environmental Sustainability – Dave Clark

Objective:To redesign dairy farm systems so that they achieve sustainability. Systemic and technological solutions will allow farmers to measure and control environmental outcomes with the same ability that they achieve production targets. This will be achieved by delivering:

  • New animal and pasture based technologies.
  • Integration of new technologies into existing and new farm systems.
  • Redesigned farm systems that break the “more feed, higher stocking rate” strategy, retain profitability and deliver major reductions in N losses.

1. P21 Phase 2 Canterbury – David Chapman

Objective:  To re-design, and capture synergies between, milking platform and wintering systems that increase productivity and decrease environmental footprint in grazed Canterbury dairy businesses.  Sub objectives include:

  • To quantify nutrient losses to the environment resulting from wintering on crops on light-textured soils
  • Investigate tactics for reducing nutrient losses, including use of fodder crops with lower protein concentration compared to kale (eg fodder beet), nitrification inhibitors, tannin-containing supplements, and ‘mop-up’ cereal crops grown in double-crop rotation with the winter crops
  • Determine the efficiency of different wintering strategies for achieving cow body condition score targets for start of lactation, and carry-over effects on lactation performance
  • Determine the productivity and nutrient loss footprint of a very high producing dairy system using high BW animals and relatively high levels of inputs (fertiliser, feed), similar to the traditional pathway for increasing productivity in the NZ dairy industry.
  • Quantify productivity and nutrient losses from a high producing, ‘efficient’ dairy system also using high BW animals, but with lower stocking rate and fewer inputs to maximise the efficiency of resource use
  • Conduct complete economic and environmental impact analysis of whole farm systems, accounting for all land and other resources used for production, over at least 4 years
  • Communicate findings to dairy business owners and providers of dairy winter grazing support in the region


2. P21 Phase 2 Otago/Southland – Dawn Dalley

  • Objective: to develop farm systems for the Southland/Otago region that are proven, profitable, simple, adoption-ready and lift production by 20% and reduce nutrient loss by 30%. 3. SY916 West Coast Monitor Farms – Dawn DalleyObjectives:
  • Develop a database of reliable pasture growth rates for 4 dairying regions on the West Coast.
  • Demonstrate the benefits of regular monitoring and feed wedge development on day to day and strategic decision making
  • Develop a database of seasonal pasture quality and its relationship to farm management decisions.


4. SY 1001/SFF 10-027 Southern Wintering Systems initiative – Dawn Dalley

Objective:  provide the framework for an integrated approach to achieving winter management practice change on dairy farms, their support blocks and with winter graziers in the southern South Island. The key outcomes will be increased adoption of wintering systems that reduce the environmental impact, are cost effective, practical to implement and meet animal welfare requirements while providing reliable sources of high quality feed. This project is designed to use farmer-to-farmer extension to increase the awareness of issues of current wintering systems and to demonstrate good management practice. Case studies and profiled farms achieving good management across a range of wintering systems will be key for successful adoption.

5. SY1002 Milking Efficiency – Jenny Jago

6. FD1004 Pasture Persistence – David Chapman

7. SY705 National Forage Evaluation Index – David Chapman

8. SY708 Whole farm model/Modelling dairy system – Pierre Beukes

ANIMALS

9. AN1004 and SFF10/024 Improving reproductive performance in large herds. Chris Burke

Objective:  to generate and deliver knowledge that supports farmers and their advisers to improve reproductive performance in large dairy herds, particularly in the South Island.

Current dairy related projects at LIC - November 2011

  • Analytics Programme:  Combining various farm information datasets then applying research and statistical analysis to create tools to enhance on farm decision making. Currently we are looking to pull together various available datasets to begin the analysis phase. The initial focus will be on reproductive performance and how we can provide timely, relevant information to farmers in a format that is easily understood.
  • Automatic Oestrus Detection:  To continually evaluate and improve our EZ Heat camera system and consider any new possibilities. Current trials are underway at various installation sites for this seasons mating.
  • Genomic Selection:  To increase reliability of DNA proofs and genetic superiority of LIC's DNA Proven sires. The next phase will be the addition of genomic information from large numbers of cows in 2011/12.  In addition we will be integrating genotypes from other parties who we have swapped genotypes with.
  • Reproduction Solutions:  This aim is to establish, develop and sustain industry momentum and appetite for continuous and sustainable improvement in the reproductive performance of the national dairy herd. Currently we are working with DairyNZ to establish a national performance benchmark for 6 week in calf rates and improving customer access to reproductive data.

  • Pasture persistence / pasture renewal: Pastures, renewed and old, in North Otago, Central and North Canterbury are monitored in this study. Tom Fraser at Lincoln leads our South Island data collection for this SFF/DiaryNZ funded project.
  • Environment - Surface Water Quality: The AgResearch Land and Environment team at Invermay lead this project which has research activities in North Otago and Southland.
  • Systems: AgResearch leads the P21 Systems Demonstration Trial at Telford, in partnership with DairyNZ.
