Method

InterPIG members select samples and data sources for their countries. The forum organizes an annual meeting where data and developments in pig production per country are presented and discussed. Collected data are also peer-reviewed among members.

The method of data collection, parameter definitions, and cost comparison has been developed and harmonized over time. Main methodological assumptions include:

• Farm-gate production costs: Costs on the farm are included, as well as direct subsidies. Levies and taxes in the abattoir are taken into account as deductions from the sales price.
• Opportunity cost method: Supplies such as labor, own capital, or farm-produced feedstuffs are valued as if purchased at market prices.
• Building costs: Calculated based on replacement values, assuming new buildings. As a sensitivity analysis, we also consider the option of using the average book value.

Costs are expressed excluding VAT and can be presented in Euros or the currency of each member country.

Due to limitations in available data and some arbitrary choices, the cost comparison is indicative for cost differences between countries and cost developments over time. Costs can be expressed in various ways, such as:

• Per kg hot carcass weight
• Per kg cold carcass weight
• Per kg live weight

Calculations are based on a closed-cycle farm model, covering piglet production, rearing, and finishing.

InterPIG does not produce a joint publication; however, some members publish data individually.
