Estimated Breeding Value (Parent Average) Calculator
Estimate an animal's breeding value as the average of its sire and dam breeding values (parent average / pedigree index).
Before an animal has its own records, its best genetic estimate is the parent average: EBV = (sire EBV + dam EBV) ÷ 2, because each parent passes a random half of its genes. This 'pedigree index' guides selection of young breeding stock.
Indicative planning figures based on published research averages. Local soil tests, varieties and weather change actual requirements — confirm with your agronomist or extension officer.

About Estimated Breeding Value (Parent Average) Calculator
An estimated breeding value (EBV) predicts how an animal will transmit a trait to its offspring. For a young animal with no performance records of its own, the best prediction is simply the average of its parents' breeding values — because each parent contributes a random half of its genes. This 'parent average' or pedigree index lets you rank and select young breeding stock before they have records, and it's the starting EBV that an animal's own performance later refines.

Frequently asked questions
How do I estimate a young animal's breeding value?+
Average its parents' breeding values: EBV = (sire EBV + dam EBV) ÷ 2. This parent average is the best genetic prediction before the animal has records of its own, since it inherits half its genes from each parent.
Why isn't the offspring exactly the parent average?+
Because each parent passes a random half of its genes (Mendelian sampling), so individual offspring vary around the parent average. The average is the expected value; actual offspring scatter above and below it, which is why progeny testing later sharpens the estimate.
Is this tool free and private?+
Yes — free, no sign-up, and all calculation runs in your browser, so it works offline at the farm and your data never leaves the device.
