BeefAI™ Champion — Comprehensive Scoring Methodology and Technical Reference

This technical reference documents the BeefAI™ Champion platform — a multi-engine genetic decision support system for Australian Angus cattle producers. It details three core engines: APEX (Angus Percentile Excellence) for scoring bulls on a 0–5.0 scale against TransTasman Angus Cattle Evaluation (TACE) breed percentiles; ACE (Adaptive Complementarity Engine) for optimising sire-to-cow mating assignments using the Hungarian Algorithm; and GENEius (Genetic Evaluation and Numerical Engine) for AI-powered genetics consultant commentary. The document covers the six-step BeefAI Genetic Optimisation Method™ including EBV percentile normalisation, goal-weighted multi-trait scoring, biological guardrails, antagonism detection, complementarity mating optimisation, and methane emission intensity modelling. It provides the mathematical formulation for scoring, tier classification, heifer safety verdicts, prepotency estimation, and selection index decision trees across all supported Angus Australia breeding goals. Calibrated to March 2026 TACE data.
