Cow-friendly wearable device

Comfortable:

A breathable neoprene headpiece minimises heat build-up and rubbing, while a flexible nosepiece allows cows to eat and drink without obstruction.

Safe:

Designed and tested on-farm, with an integrated breakaway feature designed detach if caught.

Scalable:

Device wearability allows scalable deployment – there’s no need for controlled environments or voluntary feed-station visits.

Fast, reliable results

Fast:

Minimal animal adaptation requirements, continuous sampling and fast data processing deliver results quickly - not weeks post-trial.

Reliable:

Initial evaluation trials indicate ZELP Sense can produce emission estimates of comparable reliability to existing accepted approaches.

Granular:

Users get up to four CH₄ and CO₂ readings per day (g/day), plus daily DMI estimates (kg/day – in beta)¹.

Easy-to-access support

24/7 help centre:

Videos, how-to-guides and training available via ZELP Insight.

Remote support:

Dedicated support team on-hand to help with any queries.

Warranty coverage:

12-month hardware warranty and easy-to-access replacements.

Livestock emissions measurement without the usual trade-offs

Most measurement techniques require a trade-off between accuracy, cost, labour and speed. ZELP Sense is different.

Method	Main metrics	Granularity	Cost	Labour	Behaviour impact	Scalability
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
Laser methane detector	CH₄ concentration (ppm)	Spot measurements	Low	High	Low-Medium	Medium
Sniffers	CH₄ concentration (ppm)	Spot measurements	Low	Low	None	Medium
ZELP Sense	CH₄ / CO₂ production (g/day) and DMI (kg/day)	Multiple within-day reading	Low	Medium	Low	High

Hear from our users

“ZELP Sense is an innovative way of measuring methane – it’s infinitely more portable than existing tools and allows me to get a more complete sample of my cow’s enteric methane emissions.”

ZELP Sense provides CH₄ , CO₂ and DMI estimates. Evaluation trials for CH₄ and CO₂ estimates are available here. DMI estimates are currently in beta and users will be updated once this feature is fully released.
