Regen Feature — Now Live

The BeefAI™ Regen Genetics Score (RGS) is a proprietary genetic scoring tool — distinct from grazing education programs — that analyses BREEDPLAN/TACE data specifically for producers running AMP systems. It answers a different question from the standard production $Indexes: given that this property is managed regeneratively, which genetics will best support the biological machinery the regen system depends on?

Most regen producers are still selecting bulls the same way a feedlot backgrounder does. The traits that drive profit in a conventional system are not the same traits that drive profit — and land recovery — in an AMP system. That gap is what the Regen Genetics Score closes.

Regenerative grazing is a system of biological intensification. Long rest periods allow pasture to recover fully before the next graze. High stock density during the graze event deposits organic matter, stimulates root exudation, and drives the liquid carbon pathway that builds soil carbon over time. The genetics running through that system need to be matched to it — not selected against it.

The Problem With Conventional Selection in a Regen System

Conventional bull selection optimises for growth rate and carcase weight per unit of feed consumed in a feedlot or high-input grazing system. In that system, a heavier mature cow is not a liability — supplementary feeding can offset her maintenance requirement during a dry season.

In an AMP system, that logic breaks down. The regen producer relies on the land to carry the herd. There is no feed buffer. A cow with a high mature weight is consuming pasture that should be rest-recovering between grazing events. She is compressing the biological recovery window the entire system depends on. And if she does not get back in calf quickly — or stay in the herd long enough to repay her development cost — the genetics are working against the enterprise at every level.

“Selecting bulls for regen is not just about picking low-input animals. It is about matching the genetic profile of the herd to the biological requirements of a system that generates value through soil, not supplement.”

The Four Traits That Drive the Score

The Regen Genetics Score is built on four TACE-published EBVs, each chosen because of a direct, documented biological relationship with AMP system performance.

Trait 1 — Feed Efficiency
Net Feed Intake — Residual (NFI-F)
The primary efficiency trait. More negative = less feed consumed for the same output. In a regen system with no feed buffer, feed efficiency is not a bonus — it is the mechanism that protects rest period integrity and reduces pressure on recovering pastures.
Trait 2 — Maintenance Cost
Mature Cow Weight (MCW)
Every kilogram of mature cow weight is a daily maintenance cost paid in pasture. In AMP, the paddock is the bank account. A lower MCW EBV means less daily withdrawal, longer rest periods, and more biomass available for soil biology between grazing events.
Trait 3 — Longevity
Daughter Longevity Index (DLI)
The investment in a regen herd compounds over time. A cow that stays in the herd longer deposits more dung, more carbon, more root exudation. The DLI is both an economic trait and a soil biology trait in an AMP context — the herd is part of the regen process, not just the output.
Trait 4 — Calving Window
Days to Calving (DTC)
AMP grazing rotations are planned around pasture growth phases. A tight calving window allows the highest-demand period — calving and lactation — to be aligned with peak pasture growth. A spread calving window forces paddocks offline for longer and compresses the recovery periods available to the rest of the rotation.

How It Works in Practice

The RGS is calculated from the percentile ranks of each trait, weighted according to the producer’s operation type. The result is a composite score on the same zero-to-ten scale as the existing BeefAI Champion score.

Regen Genetics Score
Regen Verdict + GENEius™ Narrative

A producer uploading a TACE document for a bull they are considering for a regen operation will receive both the standard Champion score and the RGS — side by side. A bull that looks average in the conventional index may score elite in the regen index. Or vice versa. The point is that the right answer depends on the system the bull is going into.

Why This Is DOI-Referenced Methodology

The Regen Genetics Score is not a subjective weighting scheme. Each of the four traits is linked to a documented biological mechanism. NFI-F and MCW each have dedicated BeefAI™ Zenodo publications. The DLI has its own six-trait composite methodology paper. Days to Calving is the primary fertility EBV in TACE.

The RGS methodology is peer-reviewed and fully documented. Every weight, every adjustment, and every threshold is citable. Producers, agronomists, and Scope 3 auditors can verify the logic behind every score the system produces.

Three Value Chains. One Decision.

The genetics driving a regen herd are now intersecting with three converging commercial pressures at once. The Regen Genetics Score is built to serve all three.

01
Carbon & Soil
Lower MCW and better feed efficiency means more pasture left to recover. More recovery means more root exudation, more MAOM formation, and higher soil carbon over time.
02
Compliance
Mandatory Scope 3 disclosure is arriving for Australian beef supply chains. The RGS gives producers a documented, DOI-referenced genetic credential for lower-emission herds.
03
Premium Nutrition
Research shows pasture-raised cattle have markedly different nutritional profiles — 3.1× antioxidants, 4.2× Vitamin E, 118× forage phytochemicals vs grain-fed. Genetics that keep cattle on pasture longer capture this premium.

What’s Included

Two features are included in your existing BeefAI™ subscription. A third — full land calibration — is available as a premium add-on for operations that want their genetics scored against their own country.

Included — Existing Subscription
Regen Genetics Score in the Analysis Report
Every TACE analysis for a producer on a regen or AMP operation includes the RGS alongside the standard Champion score. The bull report shows which of the four regen traits are above or below the operation threshold, with plain-English GENEius™ commentary explaining the regen-specific verdict.
Included — Existing Subscription
Regen Producer Report Template
A dedicated regen producer report integrating the RGS with the Carbon Build Momentum (CBM) score from the paddock management engine. Genetics and land performance in a single producer-facing document.
Land-Calibrated Genetic Selection
$100 / month
Full calibration of the RGS against measured pasture performance data from your own property. Your pasture recovery rates, grazing event scores, and seasonal indicators feed back into the genetic scoring weights — so the genetics you select are calibrated to your country, not a breed average. The most precise regen selection tool available in Australian beef.

The same rigour. A different question. A new score.

Peer-Reviewed Methodology

The Regen Genetics Score is built on published, citable science. Every trait weight, adjustment factor, and scoring threshold is fully documented. Producers, agronomists, and Scope 3 auditors can verify the logic behind every score the system produces.
