Your complete guide to the platform — from analysing bulls to managing paddocks and satellite data.
Sign up free at beefai.tech. Enter your name, farm name, and email. You'll get instant access to the bull analysis tools.
Go to Analyse and paste a TransTasman Angus Cattle Evaluation (TACE) link, or enter the animal's registration number. BeefAI reads the EBVs, runs them through the APEX scoring engine, and gives you a complete report in seconds.
Pick the goal that matches your operation: Balanced (all-round), Maternal (better females), Growth (weight gain), Efficiency (feed conversion), or Carcase Merit (eating quality). This changes how traits are weighted in your APEX score.
Tap the heart icon on any bull to add it to your Shortlist. Before a sale, analyse the whole catalogue, then compare your top picks side by side.
BeefAI pulls in 18+ EBV traits from the TACE database: Birth Weight, 200-day, 400-day, 600-day Growth, Milk, Scrotal, Docility, Days to Calving, Mature Cow Weight, Carcase Weight, Eye Muscle Area, Rib Fat, Rump Fat, Retail Beef Yield, IMF (Intramuscular Fat), Shear Force, and Net Feed Intake. Every trait is compared against the whole Angus breed using TACE percentile tables.
Paste a catalogue link (from Angus Australia or AuctionsPlus) and BeefAI will analyse every lot in the sale. Bulls are ranked by APEX score so you can quickly see which ones suit your breeding goal. You can filter, sort, and shortlist from the results.
BeefAI works with additive genetic predictions (EBVs). It cannot see phenotypic traits like structural soundness, udder quality, temperament in the paddock, or development environment. Always inspect bulls in person. EBVs tell you what an animal can pass on genetically — not what it looks like today.
The APEX score (Angus Percentile Excellence) is the overall rating for a bull against your chosen breeding goal. It measures multi-trait percentile positioning, trait balance, and biological stability within the Angus breed.
| Score | Rating | What It Means |
|---|---|---|
| 4.5 – 5.0 | Exceptional | Elite across multiple traits — rare genetics |
| 4.0 – 4.4 | Very Strong | Well above average, minor gaps only |
| 3.5 – 3.9 | Above Average | Solid all-round — a reliable choice |
| 3.0 – 3.4 | Average | Middle of the breed — some strengths, some weaknesses |
| Below 3.0 | Below Average | Significant gaps — check the trait breakdown |
A Curve Bender breaks the normal pattern where high growth comes with heavy birth weight (and calving trouble). These bulls have moderate birth weight combined with elite 600-day growth — meaning fast-growing calves without the calving risk. BeefAI flags them automatically. They're uncommon and valuable.
Cow Economics looks at what kind of females a bull will produce. Key signals:
| Signal | What It Means |
|---|---|
| Heavy Cows | His daughters will be big-framed — you'll run fewer per hectare and use more feed per cow |
| Above-Average Cows | Moderate-to-large daughters — watch the stocking rate impact |
| Moderate Cows | Efficient daughters that suit grass-based systems — the SAV ideal |
| Lighter Cows | Smaller-framed daughters — can run more per hectare but check growth isn't sacrificed |
The Maturity Pattern (Early, Balanced, Later) tells you when daughters will finish — earlier-maturing cattle suit shorter supply chains.
Tap the heart icon on any bull card or analysis page to save it. Your shortlist persists across sessions — add bulls from different catalogues and sales, then review them all in one place.
Select two or more bulls from your shortlist and tap Compare. You'll see their APEX scores, trait radar charts, top strengths, and key risks side by side. This is your decision tool on sale day.
Go to Grazing → Properties and add your farm. Enter a name and GPS coordinates (latitude/longitude). This anchors your property on the satellite map.
You can add paddocks two ways:
• From the Paddock Map: Click "New Paddock" and draw the boundary directly on satellite imagery. BeefAI auto-calculates the area from your drawing.
• From Properties: Add a paddock with name, area (hectares), and soil type. You can draw the boundary later on the map.
Create mobs (groups of cattle) from Grazing → Mobs. Give each mob a name (e.g. "Heifers 2025", "Steers Lot 1") and head count.
When you move cattle into or out of a paddock, record it: select the mob, enter the date in and date out, and the head count. This builds Paddock Memory — the history BeefAI uses to calculate rest periods, grazing pressure, and health scores.
The Grazing Dashboard shows your farm at a glance:
• CEI (Carbon Efficiency Index): Your farm-wide biological efficiency score (0–100). It links genetics, climate, and pasture into one number.
• Status: "Building" (improving), "Holding" (stable), "Slipping" (declining), or "Under Pressure" (needs attention).
• Drought Alerts: Automatic warnings based on BOM rainfall data — no rain gauge needed.
• Paddock Cards: Each paddock shows its CBM (Carbon Momentum) and SHP (Soil Health Proxy) scores, plus current status.
The map shows all your paddocks on satellite imagery. Colours tell you the status:
| Colour | Meaning |
|---|---|
| ■ Green outline | Paddock boundary drawn |
| ■ Blue outline | Currently drawing a new boundary |
| ■ Orange fill | Mob currently grazing in this paddock |
Click any paddock on the map to see its details, mob history, and satellite connection status.
BeefAI connects to the Sentinel-2 satellite (European Space Agency) to read your paddock's vegetation health from space. It measures NDVI (Normalized Difference Vegetation Index) — essentially how green and photosynthetically active your pasture is.
• Sync All: On the Grazing Dashboard, tap the "Sync Satellite" button to pull the latest data for all your paddocks at once.
• Sync One: On any paddock's detail page, tap the "Sync" button to update just that paddock.
• Connect to Satellite: On the Paddock Map, click a paddock and tap "Connect to Satellite" to link it for the first time.
After syncing, BeefAI calculates the OPF score (0–100) for each paddock. It combines four things:
• NDVI Level (20%): How green is it right now?
• NDVI Trend (20%): Is it getting greener or browning off?
• Recovery Response (30%): How well does it bounce back after grazing?
• Seasonal Cycle (30%): Is it performing as expected for the time of year and soil type?
When you analyse a catalogue, BeefAI can generate a Carbon Report for the bulls. This evaluates the environmental footprint of their genetics using three metrics:
• MEI (Methane Intensity): How much methane per kg of beef produced
• NFI (Net Feed Intake): Feed efficiency — lower is better
• CER (Cow Efficiency Rating): How much maintenance the daughters will cost
The RGS rates bulls specifically for regenerative grazing systems. It deliberately diverges from the APEX score — a bull can be commercially excellent but unsuitable for regen if his daughters are too heavy or too hard to get in calf.
| Tier | What It Means |
|---|---|
| AMP Ready | Genetics aligned with Adaptive Multi-Paddock grazing — efficient, fertile, moderate daughters |
| Regen Aligned | Good fit for regenerative systems with minor trade-offs |
| Conventional | Better suited to higher-input, conventional production systems |
| Regen Risk | Genetics that work against regenerative goals — heavy, high-maintenance daughters |
The CEI on your Grazing Dashboard is different from the Carbon Report. It combines your actual satellite data (pasture health) with genetic backbone (the bulls you're using) and management signals (rest periods, stocking rate) to give a real-time measure of your whole farm's biological efficiency.
My Herd lets you record the animals currently on your farm — cows, bulls, and calves. Log weights, scan data (EMA, IMF), health treatments, and calving events.
Once you've recorded calving and weight data, BeefAI compares the predicted performance (from EBV analysis) against actual results from your calves. This closes the loop — you can see if a bull is delivering what his genetics promised.
This usually means one of three things:
• No location set: The paddock doesn't have a drawn boundary or GPS coordinates. Go to the Paddock Map and draw the boundary.
• Cloud cover: The satellite couldn't get a clear view. Try syncing again in a day or two.
• Session expired: If you've had the page open for a long time, refresh the page and try again.
This means your session timed out. Simply refresh the page and try again. This can happen if you leave a page open for a long time without interacting.
Make sure your property has GPS coordinates set, and that the paddock either has a drawn boundary or a centre point (lat/lon). Paddocks without any location data won't appear on the map.
Check that you're pasting a valid TACE link or registration number. BeefAI needs to find the animal in the Angus Australia database. If the bull is very new or from a private sale, the data might not be published yet.
Contact us at beefai.tech/contact and we'll sort it out.
