The numerical productivity, evaluated as the number of weaned piglets per sow and year, has increased year after year in pig farms during the period 1981-2013, according to the information published in the last annual report written by the ‘Grup de Gestió Porcina’ (Pig Management Group) of the Animal Production Department at the University of Lleida.
During this 32-year period, France has been, continuously, the country with the highest productivity in comparison with Spain and The Netherlands, reaching 28.70 weaned piglets per sow and year in 2013. In the last five years, the number of piglets weaned per productive sow and year in the Dutch farms has diverged from that of the Spanish and Catalonian farms. With respect to the previous year (2012), the numerical productivity has increased in all the analysed countries.
