We’re pleased to let you know that new materials from the new Zealand Climate Smart Agriculture Initiative are now available on the website. These resources focus on livestock greenhouse gas measurement and may be useful to your work or to others in your networks.

You’ll find the new content under the Livestock Emissions Measurement section, located within the Livestock Research Group → Collaborative Activities. This page brings together practical information on key measurement methods including respiration chambers, the SF6 tracer technique, headbox systems, and the Greenfeed emission monitor.

Under this section, two new technical pages have been added:

• Headbox Respiration Systems – includes documents such as Headbox Best Practice and Headbox Troubleshooting Advice, along with a YouTube playlist covering design and operation, developed for the international workshop hosted in Cambodia’s Royal University of Agriculture in 2025.
• Greenfeed Emission Monitor – features training videos from the workshop on Quality Assurance for Greenfeed Users held at the University of Los Baños – Dairy Training and Research Institute. This workshop was jointly led by the Philippine and Vietnam Greenhouse Gas Measurement Hubs, with support from the New Zealand Government and the University of California, Davis.

A series of 4 engaging online workshops exploring innovative research and practices for soil health, carbon sequestration, and sustainable land management.

Abstract: The red seaweeds, Asparagopsis taxiformis and A. armata inhibit methane production in ruminants, considered to be mediated by bromoform. This review examines the toxicology, metabolism, epidemiology and pharmacology of bromoform. IARC concludes bromoform is not classifiable as a carcinogen to humans, whereas the US EPA classifies it as a probable human carcinogen based on a low incidence of intestinal tumours in female rats given high gavage doses chronically. Under the same conditions, mice exhibited no tumours, suggesting that tumour formation is secondary to localised cytotoxicity. While there is some in vitro evidence of mutagenic potential for bromoform, likely via a metabolic pathway involving GSTT-1, this pathway is unlikely to be relevant at low doses. The human evidence, from drinking water disinfection by-product studies, is inconclusive. While some residue studies find bromoform in milk, the concentrations approach background levels and pose no significant cancer risk. The collective implication of these findings is that bromoform, as an environmental inhibitor, does not pose a significant risk. A precautionary approach would ensure that bromoform intake does not exceed the capacity for rumen degradation such that concentrations of residues in tissues and milk and consequent dietary exposure are minimised and below relevant health-based guidance values.

The Ag Emissions Centre is seeking an experienced Project Manager to support a multi-country science team, report and deliver the project on time, and within budget.

The CH4IEF project (Methane Inhibition and Electron Flow) is a groundbreaking animal trial exploring the long-term use of methane inhibitors in ruminants – uncovering their effects on native microbial communities and advancing the science behind methane production and its connection to animal productivity. You’ll be working with a global science team and helping uncover new pioneering insights.

Key responsibilities:

• Support planning and timely delivery of research activities

• Implement effective budget monitoring and control

• Coordinate high-quality reporting to funders

• Ensure robust documentation, data storage, and archiving

• Lead internal/external communication and info-sharing
