Pig farms with Topigs sows produced an average of 28.8 weaned piglets per sow per year in 2011, according to the company's latest report — the technical results from 678 Dutch farms with a total of almost 332,0000 sows.
The top 10 percent of farms achieved 31.6 weaned piglets per sow per year. In 2011 the production of Topigs sows rose by 0.7 piglets. This is a bigger increase than in previous years where the average was 0.5 piglets per year, according to company data. Despite the increase in production, piglet mortality remains at roughly the same level as several years ago, and the sow replacement rate has not risen, either.
A growing number of farms are weaning 30 or more piglets per sow per year. In 2011 a total of 164 farms achieved this and 16 farms achieved a production of 32 or more piglets per sow per year.
