GB sow productivity continues to rise

In the 12 months ending June 2017, the productivity of the GB sow herd continued to increase, according to latest data from Agrosoft.

Although there was an improvement recorded in the productivity of the breeding herd, the GB herd is still behind the EU average, when compared with the most recent InterPIG figures from 2015. The EU average for 2016 was 26.81 pigs weaned per sow per year compared to the GB average for the 12 months ending June 2017 of 25.36 pigs weaned per sow per year.

The performance of the GB feeding herd was more mixed. The daily live weight gain for rearing pigs increased on the quarter, contributing to an improvement in the feed conversion ratio (FCR). For finishing pigs, the daily live weight gain decreased, but the FCR remained unchanged, suggesting that overall, less has been fed to the herd per day.
