How does genomic selection increase profitability?
But will the cost eat into profits?
The Pig Improvement Company has mapped its genetic gain index over time, which demonstrates the added value since switching to relationship-based genomic selection in 2013. The graph below shows a doubling of genetic gain when using relationship-based genomic selection versus pedigree selection. PIC have calculated that their Relationship-Based Genomic Selection programme has led to a profit improvement of £ 2.70 to £ 3.10 per pig per year due to a 35% increase in genetic progress per year for all traits.5
It works, but isn’t targeted genotyping via NGS expensive and inflexible?
- up to 5K SNPs with Flex-Seq LD
- 7K-10K SNPs with Flex-Seq MD
- up to 30K SNPs with Flex-Seq HD
Here's how it works
|Figure 2 – Illustrative example of the Flex-Seq protocol, highlighting the probe hybridisation to two hypothetical targets and their path via NGS sequencing to genotypic information.|
|Figure 3 – Representative loci recovery and uniformity for panels in A) Cattle, B) Porcine, and C) Chicken. The X-axis represents the loci targeted in each panel and the Y-axis represents the amount of sequencing data (log 10 transformed) that each loci received. Data for up to five representative samples are shown for each panel alongside the median.|
