Tainted pork is latest food scandal to hit China, March 17, 2011
------Products marketed under Shuanghui Group's Shineway brand were produced from pigs that were fed clenbuterol, an additive that can speed up muscle building and fat burning to produce leaner pork, the reports said.The additive, known among farmers as "lean meat powder", is banned in China because if eaten by humans it can lead to dizziness, heart palpitations and profuse sweating, the reports said……

Recent history
1910: Start of Herdbooks 1990: Merger of Herdbooks 1996: Acquisition of Dalland 1998: Acquisition of Fomeva 1999: Founding of TOPIGS 2003: Acquisition of Dumeco Breeding 2008: Merger of Dutch A.I.’s into Varkens K.I. Nederland as
part of TOPIGS
Result: The National Dutch herdbook breeding program again in one company

Heat stress
Pigs are not able to sweat and pant
Thermo-neutral zone of sows: Range of temperatures between which an animal
feels comfortable Between 12°C and 22°C (Black et al., 1993
Sows inseminated during hot period have lower reproductive performance

Genome sequence => very many SNP’s
Technology for large- scale genotyping at low-costs

What is a SNP ??SNP = Single-nucleotide
polymorphismA DNA sequence variation
occurring when a single nucleotide — A, T, C, or G — in the genome (or other shared sequence) differs between paired chromosomes
For example, two sequenced DNA fragments from different individuals, AAGCCTA to AAGCTTA, contain a difference in a single nucleotide. In this case we say that there are two alleles : C and T.
SUNJIN July 15 2009 24
Quantitative versus Genomic selection for reproduction
Quantitative selection until today very effective for quantitative traits
New options for PRRS resistanceImpact of genomic selection dependent
upon:1. costs of SNP genotyping (50.000
300.000 SNP’s)2. added value of SNP for accuracy of
breeding value: costs benefitsIn near future combination of Quantative &
Genomic selection expected!!!

Balanced breeding !!How to ensure more reproductive sow without problems
for health or vitality of piglets and sow? more piglets born alive, less death more piglets born alive but also weaned high reproductive sows but less culling PERFORMANCE WITH NO HORMONS =
FOOD SAFETY TOPIGS uses selection strategy that takes these
aspects into account
SUNJIN July 15 2009 26
The sow of 2020
There will be further genetic improvement of litter size along balanced breeding
Extra piglet born Extra piglet weaned Dedicated quality improvement along:
wider temperature neutral zone Improvement of vitality/disease resistance application of new genomic tools
Sow 2020: >15 piglets born alive => 14 piglets weaned/litter without intensive human support
