Pig-farm KPI benchmarks, by country

The same PSY can mean “excellent” in one market and “average” in another. Cohort, data source, denominator and weaning age all move the number — so a single figure without context is misleading. This page explains how PigOS reads swine KPIs and shows industrial-farm reference ranges by country.

What is PSY (and MSY)?

PSY (piglets/pigs per sow per year) counts how many piglets a sow produces or weans in a year. MSY (market pigs per sow per year) counts how many reach market — it folds in post-weaning survival. PSY measures the breeding herd; MSY measures the whole operation. Both depend on how you define the denominator (total sow inventory vs. mated female inventory), the weaning age, and whether you count born, weaned or sold.

Industrial-farm reference ranges (PSY)

Public-benchmark ranges for well-managed industrial farms — not national averages. * = wider source/definition variance.

Why the same number differs

Denominator (all sows vs. only mated females), weaning age (21 vs. 28 days shifts weaned counts), genetics, herd health status, recording standard, and whether the figure is a national average or an industrial-farm cohort all change the result. PigOS calibrates each KPI to your country, year, farm type and data definitions rather than a single global threshold.

Ranges are illustrative reference points and not guaranteed results. PSY/MSY vary by source and definition.
