3. UCD Lyons Research Farm

Funding is provided for the research programme for the Development of a high-output grass-based spring milk production system. This research programme commenced at the beginning of January 2019, and is for an initial 3 year period. It will then be reviewed, and may be continued for a further period, depending on progress.

The aim is to

  • To incorporate the most recent advances in grassland management for dairy farms
  • Use a type of dairy cow that did not exist 15 years ago that has high milk output and fertility
  • Employ the best practices from nutrition research and dairy cow husbandry

The research will

  • Continue to evaluate a higher output spring system
  • Produce KPIs suitable for high out grass based milk production (grass, milk, fertility).
  • Optimise cow genotype in the system
  • Evaluate different nutritional strategies and management strategies in the system

Dissemination is via

  • Weekly notes published on the Lyons Farm Website
  • Hosting industry groups on an ongoing basis
  • Reports in the main agricultural media

4. UCD Veterinary Faculty

Funding is provided for a Calf Housing & Pneumonia Project which will run for a 4 year period, commencing at the beginning of 2019.

Key questions which this project will address for dairy farmers, vets and advisors will be:
1. How can we use modern technology to better assess calf housing?

  1. Can we use better, modern diagnostics to diagnose calf pneumonia?
  2. Knowing these, how can we modify existing calf houses to reduce the risk of calf pneumonia?
  3. What are the long-term health/growth/fertility cost-benefits for the heifer calves coming into the milking herd in two-years time?

5. NUIG Novel Slurry Treatment and Management Technology

This project presents a novel additive treatment of farm slurry to (1) significantly reduce GHG and toxic gas (ammonia and hydrogen sulphide) emissions from milk production and during slurry storage, while (2) enhancing the value and energy potential of the treated slurry for anaerobic digestion and (3) providing an enhanced slurry-fertiliser for grass production, reducing the requirement for mineral fertilizer.

NUIG has developed Methanogen Inhibiting Reactive Species, which is an innovative platform technology to eliminate GHG emissions from organic residues and animal manures.

In preliminary laboratory and pot-scale work carried out at NUIG, after 14 weeks of storage, treated dairy manures

  • Had emitted over 98% less GHG than untreated controls
  • Had an increased nitrogen content (up to 400% greater than untreated controls)
  • Enhanced crop yields (by 15%) when used as a fertilizer in pot-trials
  • Could displace chemical fertilizer (by 40%) compared to untreated controls
  • Increased biogas output by 40% during AD, yielding major economic benefits.

The product is safe and generates no environmentally harmful residues and contains only food-safe ingredients.

Preliminary work has been carried out, which confirms the findings at lab scale in NUIG, and has identified a final formulation for pilot testing at the instrumented slurry storage facility in Johnstown Castle. This facility will allow for replicated, control testing and will generate data suitable for international publication. Two portable gas analysers are available to allow the technology to be tested on two working farms.

This project commenced in September 2020, and is expected to be completed at the end of October 2021.

6. VistaMilk 4 year programme to quantify carbon sequestration in grassland

The project commenced in February 2021, and is a four year project. Science Foundation Ireland provides the bulk of the funding and Dairy Research Ireland provides the industry contribution.

The new National Climate plan aims to reduce GHG emissions from the State by 51% by 2030, and this poses a considerable challenge for Irish Agriculture. Enhancing soil organic carbon (SOC) sequestration and reducing soil-based CO2 emissions offers the potential to reduce emissions whilst maintaining productivity and to further reduce the C footprint of Irish agricultural produce.

Agricultural soils are currently reported as a net source of carbon emissions due to historic drainage of peat soils for agricultural use. Correct management of drained peat soils provides an opportunity to reduce emissions and protect our largest carbon sink, with over a billion tonnes of carbon stored in these soils.

Enhancing C sequestration also offers value for money, with abatement from organic soils alone representing savings ranging from €109m to €327m over the period 2021-2030. National data are required to better quantify soil carbon emissions and sinks from agricultural land, enable mitigation measures that increase carbon sequestration to be included in the national inventory, and enable Ireland to benefit from the 2018 EU Effort Sharing Regulation.

Accurate estimates of net emissions from our drained organic and CO2 sinks associated with mineral soils is essential to enable the sector to achieve the ambitions set out in the Programme for Government, and the EU Farm to Fork communication strategy, as well as having the potential to create a very positive narrative around emissions in agriculture for the dairy sector.

Changes in SOC in response to land use change or land management change are small relative to background SOC levels and it can take a number of years to verify measurable levels.

The project will involve Soil C Monitoring on a variety of soils and management types, CO2 Flux monitoring, Field Scale monitoring for mineral soils, remote sensing and activity data and ecosystem modelling of Carbon, Nitrogen and water cycles, building on the recent investment in this area by the Department of Agriculture, Food and the Marine.

The outputs will be

  • Quantification of gross sequestration of managed pasture across a range of soil types for inclusion in Life Cycle Assessment.
  • It will quantify the C sequestration potential of pasture management, and establish the relationships between changes in CO2 fluxes and changes in soil C pools associated with pasture management.

Modelling of C sinks and sources will allow for a move to Tier 3 land management factors. Refinement of the models will allow for the development of more accurate decision support tools for farmers in terms of relating sward management decisions to enhanced C sequestration.

7. Accelerating the rate of genetic gain in both dairy and beef cattle and increase the value of beef output from the dairy herd using in vitro produced embryos.

This project, to be undertaken by Teagasc, was approved for funding in March 2021.

The project will establish a methodology to use Assisted Reproductive Technologies to intensively select for genetic improvement in dairy bulls and beef breed bulls suitable for use in the dairy herd. This is necessary to continue rapid genetic gain in the face of greater sexed semen usage, which will diminish the number of male dairy calf births.

It will also test the economic feasibility of using embryos with greater than 75% beef breed genetics on dams not suitable for generating replacement heifers. The aim is to transform the dairy herd calf crop to a combination of high genetic merit dairy female calves and premium quality beef calves.

There will be three complimentary studies

  • Evaluate the potential to accelerate genetic gain in dairy cattle (EBI).
  • Evaluate the potential to accelerate genetic gain in beef bulls suitable for use on the dairy herd (DBI).
  • Evaluate the potential to use low cost beef embryos to impregnate dams that are not suitable for generating replacements (commercial beef).

8. Comparison of IgE-Mediated Cows Milk Protein Allergy (CMPA) Management Strategies.

This project was approved for funding in March 2021, and the National Dairy Council is also contributing to the project.

The research study will be conducted by Dr Juan Trujillo Wurttele from Cork University Hospital. He is a specialist in paediatric allergies and sought support for a preliminary study to retrospectively look at data collected from three hospitals, all using different protocols to treat CMPA.

From his observations he has seen that controlled exposure to cows’ milk is associated with better outcomes, and that complete avoidance is associated with less favourable growth and development. The study will analyse the data which could verify these observations, and this study could provide data which could enable Dr Trujillo build his research into a bigger intervention.

The findings will be published in a high impact journal, will be presented at an international conference, be disseminated to health professionals and outcomes highlighted in the media.
