The genetic sequence of the first pig, a red-haired Duroc boar, was published in 2012. This milestone was achieved through a global collaboration that has resulted in valuable insights for agriculture, medicine, conservation and evolution. Since then hundreds of porcine sequences have been completed as the cost of the technology continues to decline. Sequence information can be analyzed directly, used for comparing animals within a breed, or for comparing animals across breeds.
One category of genetic difference frequently used for comparison is ‘Single Nucleotide Polymorphisms’ or SNPs (pronounced ‘snips’). SNPs are used as genetic markers to track the ancestral heritage of regions of DNA or of individual animals. SNPs also can be used to predict the likelihood that a given animal will possess an individual or a series of trait(s). The latter can only occur once a SNP or a collection of SNPs is linked to a particular trait.
In our projects, genotype information from a wide range of swine breeds are used to develop accurate genomic predictions to assess the genetic potential of individual animals for various production, health, and quality traits. This information will, in turn, be used to make genetic improvement in Canada's swine populations.
Low-density (and low-cost) tests have developed that allow an animal's entire genome to be inferred from a comparatively small number of SNPs, thereby giving valuable information as to its breeding value. Our projects work with scientists (and data) from around the world, as well as leading Canadian and international pig breeding organizations.
Livestock Gentec is currently involved in 12 swine projects, many of which include collaborations with scientists at leading institutions, nationally and internationally.
