TOPIGS Genetics: 26.36 Weaned Piglets / Sow / Year
THE NETHERLANDS - Dutch pig farmers with TOPIGS sows achieved an average production of 26.36 weaned piglets per year in 2007. Compared with 2006, this is an increase of 0.65 piglets.
This picture emerged from the technical results of 942 farms with a total of more than 368,000 sows. The top 25% of farms realised an average of 28.52 piglets per sow in 2007. A result of 30 or more piglets per sow per year was achieved at 22 farms. In 2006 only 9 farms achieved a result of 30 piglets or more. See also the table and graph.
From the 2007 results we can conclude that the approach of TOPIGS in the areas of piglet survival and piglet vitality works. In 2007, 12.75 piglets were born per litter, whereas in 2006 that was 12.47. This is an increase of 0.28 piglets per litter.
The preweaning mortality fell slightly from 12.2% to 12.1%. This goes against the widespread opinion that mortality will rise with increasing litter size.
