Read this before you buy anything

What this will not tell you.

All of this appears inside the software too, printed on its own sheet in every export. You should be suspicious of breeding tools that don't publish their limits.

Predictions are midparent averages

When planning a joining, the predicted progeny figures are the average of the two parents' breeding values. That is the standard arithmetic and it is sound — but it is the expected average across many calves, not a forecast for any one of them. Each calf gets a random half of each parent, so individuals vary widely around that average.

One record proves little

A single good carcass is weak evidence about any sire. The by-sire table is worth reading once a bull has numbers behind him, not before. We show the count alongside the average for exactly that reason.

It is not a pedigree tool

No coefficient of inbreeding, no coancestry. Relatedness screening reaches only as far as the sire recorded against each female. If you need true pedigree maths you need MateSel through your breed society — this complements it rather than replacing it.

It is only as good as your data

Every EBV carries an accuracy figure, and we use it — a breeding value from a young unproven sire is pulled toward the breed average in proportion to how little evidence sits behind it. But if what you upload is out of date or incomplete, the recommendations inherit that. Pull a fresh AWA export before a joining.

Feed is reported, not modelled

Your kill sheets carry days on feed, so we show what your own cattle did at different lengths of feeding. That is history, not cause — the mobs fed longest are often the ones chosen for it. We will not tell you what a ration will do to marbling, because that needs a controlled trial rather than a spreadsheet.

It doesn't decide anything

The output is evidence for you or your consultant to weigh. The decision, and the responsibility for it, stays with the breeder.

Still worth a look?

If none of that put you off, the consult costs nothing and you'll know within an hour whether this is any use to you.
