Updated CV 07-Jul-2023
The evolution of multi-site pig production over the last 25 years has not held true to its original intent.
In a previous article (March '99) we suggested a standardized terminology for the description of swine production systems. The terminology covered stages of production (breeding, nursery, finishing), management practices (isowean, sourcing of pigs, movement of pigs), and physical aspects and geographical locations of production facilities (numbers of buildings, loci, and sites).
A new proposed system for terms to use in describing the various one site and multi-site production systems that have evolved in the pork production industry, and a simplified system for diagraming various types of pig farms.
