Genetic gain
Is your herd's genetics heading the right way — and fast enough to stay ahead of your costs? Two views answer that, then the per-trait detail below.
Gain vs your cost of production
Your realised genetic-merit trend against your own cost of production — both per breeding cow (cows + heifers; bulls and steers excluded so the two lines share one denominator), both as change from the base year. Merit climbing faster than cost is real-terms gain; cost climbing faster is the signal to act. Your numbers only — no market or commodity prices in this chart.
Enter as many past years as you have — the chart works straight away. One deliberate figure per year (tax time is a good prompt). This is your own all-in running cost per cow, not a benchmark.
Maternal ↔ terminal drift
Where each birth-year cohort sits on the maternal–terminal axis, valued on your enterprise weights — the direction your herd's genetics have been travelling. Some operations want to lean terminal, others maternal; this just shows which way you've gone, so it's a choice and not an accident.

Selection differential per cohort
Top-decile minus whole-cohort mean, year by year. Bigger differential = stronger selection that year.
Counterfactual — what if you selected harder?
Response per year using R = h² × i × σ / L. Real intensities depend on which animals you actually breed from.
