TOPIGS Combines Genomic Selection with Pigbase
28 April 2011
NETHERLANDS - TOPIGS has linked the emerging technology of genomic selection to Pigbase, its enormous databank.
Pigbase contains phenotypic information from almost 23 million pigs.
This link up maximises the benefits that can be obtained from genomic selection. TOPIGS
expects to achieve significantly more genetic progress in the near future as a result of
this.
Over the next few years, TOPIGS will invest several million euros in genomic selection to
fully utilise and introduce the possibilities of this highly promising technique into
everyday breeding practice. With this initiative TOPIGS will remain one step ahead of
other breeding organisations.
Genomic selection makes it possible to directly see what the genetic disposition for a
certain characteristic is. Faster genetic progress will be made, especially for
characteristics that are only visible later in a pig’s life, are sex-linked or have a low
inheritability. Genomic selection also makes it possible to work with specific breeding
objectives, such as selecting against the occurrence of boar taint.
TOPIGS’ breeding databank Pigbase contains phenotypic information from 23 million pigs.
For example, each year the individual birthweight of more than half a million piglets is
determined. On top of this, the individual feed uptake of more than 20,000 breeding pigs
is recorded each year and 3500 carcasses are dissected. Furthermore, a wide range of
growth data, backfat measurements, fertility data, litter data and other details are also
collected and recorded.
