What is it?

SmartWorm is a world-first app to enable farmers conduct targeted selective worm treatment (TST) based on an advanced algorithm. This enables a sheep farmer to reduce their use of wormers by 40% without any loss of animal performance. This is achieved by identifying in real time which animals would or would not benefit from a wormer treatment.


The algorithm calculates a lambs potential growth rate based on a number of factors (liveweight gain, rainfall, temperature, pasture availability and pasture quality) and gives them an individual target. If they are not reaching this target, it recommends treating the animal.

Why use it?

Controlling parasites is one of the biggest challenges facing sheep farmers. Modern parasite control is becoming unsustainable due to resistance issues with anthelmintics (wormers) on most farms, and is costing farmers millions each year. The 2015 WAARD Project in Wales showed that out of 47 farms tested, 94% have resistance to Benzimidazole (1-BZ), 68% have resistance to Levamisole (2-LV) and 51% of have resistance to Ivermectin (3-ML).


SmartWorm preserves the efficacy of anthelmintics by reducing their use to as much as necessary but as little as possible. This is crucial to maintain existing production levels, protect social licence and facilitate the sustainable intensification of agriculture into the future.

"Key for me in using this solution was that it fitted into the existing schedule of handling my lambs every 4 weeks. It worked very well – I saved some drench, it was much faster dosing the lambs because I don’t have to dose them all, and there was no loss of performance. It’s a no brainer.”

"Not only did I use less wormer, but I’m now able to select replacements that require less worm treatments. Therefore, I expect the wormer reduction to get better because I can now breed sheep who are resistant and resilient to worms. I feel I’m making a huge contribution to enhancing biodiversity and soil health on the farm due to the significant reduction in wormer use.”

Using SmartWorm, Brian reduced wormer use by 42% with no loss of performance.

Features of SmartWeight:


- Selective worming algorithm: just two inputs - estimate of pasture availability since last weighed (cm's), and pasture quality (Poor, Average, or Good). Requires no internet, instant calculation


- Worm R/R Rating: using the algorithm data, our app generates a rating out of 10 that tells you how resistant/resilient the animal is to worms. You can selectively breed the best, and cull the worst animals to improve the natural parasite resistance/resilience within your flock

- Advanced weighing functionality: rapid weight capture, ADG and life data in real time


- Individual animal record card: weight and treatment history of your animal


- Comprehensive medicines database: record selective, whole group & individual treatments on the fly during a weighing session


- Extensive session stats: min/max weights, avg weight & ADG, % dosed/not dosed


- Output integration: export the output information and import into your sheep management software (TGM, Border Software, Shearwell, AgriWebb etc.)


- Installable on any Apple/Android phone or tablet

What you need (3 bits):

SmartWorm is best used with the Cotter Crate, but it also works with other sheep handling and weighing equipment you may already have on farm.

Compatible equipment:


WeighRite (recommended*)

Tru-Test S3

Tru-Test EziWeigh7i (Android only)

Tru-Test XR5000 (Android only)

Any weigh crate

with digital weigh bars (Trutest,

Gallagher, Shearwell etc.)

EID readers

Agrident AWR300

Agrident AWR250

Agrident APR600

Agrident APR250

Tru-Test XRS2 

Tru-Test SRS2

Allflex APR Reader


*If your equipment is not listed,

please contact us to add integration

If you're already fully equipped with:

1. Weighhead

2. Weigh crate with digital weigh bars 

3. EID reader

you can get selectively treating immediately.

Example existing equipment setup:

- Tru-Test XR5000 weigh head

- Prattley 3 way draft crate

- Agrident AWR300 EID stick

- SmartWorm App on phone/tablet


Step 1: Plug your weigh bars into your weigh head. Connect your weigh head by bluetooth to the SmartWorm app

Step 2: Connect your EID stick reader to your phone via bluetooth

Step 3a - if using a sheep handler (Cotter Crate/Combi Clamp/Clipex/Te Pari): the app will show in real time who does/does not need treatment with a green or red mark. Dose the red ones. The app will record the red ones as dosed.


Step 3b - if using a drafting crate: Click the "treatment" draft option in the app. This will draft the ones marked green (no dose) one direction, and draft the ones marked red (need a dose) the other direction. Run your animals through and draft accordingly. Then dose all the red group.
