The use of benchmark results is not a new concept in swine production but has been minimally utilized in nursery and grow-finish pig production. Measuring nursery and growing pig performance is of paramount importance for a number of reasons. These include: identifying strengths, weaknesses and opportunities compared to defined targets; performing corrective diagnostics; assessing plans and progress, either technical or financial; assessing the value of a business proposal; and most importantly, to compare and benchmark. Benchmarking tools incorporating technical and financial metrics are also useful for validating the on-farm effect of new technologies and feeding strategies, including those derived from growth simulation models. This paper will highlight the power of benchmarking and describe experiences with a proprietary system, Compiporc. Closeout results for nursery and grow-finish pigs are entered into the Compiporc system according to the farm details. Wean-to-finish performances are not currently included, but will be part of future enhancements. Currently the Compiporc database contains closeout data since 2000, which includes over 8,000,000 nursery and grow-finish pigs. Various reports can be produced for nursery and grow-finish including: a general benchmark report, a technical and economical report per period, a nutrient management report and a slaughterhouse report. The use of benchmarking data to support decision-making processes has always and will continue to be of crucial importance in pork production. This paper illustrates a few examples of how it has been and could be used but there are endless other ways of mining the data to improve performance and profitability.
