Farm-ready hardware

Comfortable: Ventilated neoprene reduces heat build-up and minimizes risk of rubbing.
Allows natural behavior: Flexible baffle arms allow cows to eat, drink and groom without obstruction.
Secure: Multiple sizes and adjustable straps ensure a snug, secure fit across cows.
Robust and safe: Designed and tested on-farm, with an integrated backflush to reduce clogging and a breakaway mechanism to ensure the device detaches if caught.
Fast, granular results

Fast: Minimal adaptation period, continuous sampling, and fast data processing delivers results in as little as 48 hours1.

Flexible granularity: Adjustable sampling modes allows users to optimise for granularity or battery life, with up four readings per day – CH4, CO2 and DMI in grams/day.

Actionable insights: Pre-set dashboards show individual data, group comparisons and animal rankings. Data can be downloaded for further analysis and reporting.
Easy-to-access support
- 24/7 Resource Hub: How-to-guides and training videos directly accessible via ZELP insight.
- Fast troubleshooting: Dedicated support team on-hand to help with any technical queries.
- Warranty coverage: 12-month hardware warranty and easy-to-access replacements.
| Method | Main metrics | Granularity | Cost | Labour | Behaviour alteration | Throughput |
|---|---|---|---|---|---|---|
| Respiration chamber | CH4 / CO2 production (g/day) | Multiple within-day readings | High | High | High | Low |
| SF6 technique | CH4 production (g/day) | One daily estimate | High | High | Medium | Medium |
| GreenFeed | CH4 / CO2 production (g/day) | One daily estimate | Medium | Medium | Medium | Medium – can only sample animals that adapt to using unit |
| Laser methane detector | CH4 concentration (ppm) | Spot measurements | Low | High | Low-Medium | Medium |
| Sniffers | CH4 concentration (ppm) | Spot measurements | Low | Low | None | High – but can only be used in trough/dairy settings |
| ZELP Sense | CH4 / CO2 production (g/day) and DMI (g/day) | Multiple within-day reading | Low | Medium | Low | High |
