This is our Friday rubric: every week a new Science Page from the Bob Morrison’s Swine Health Monitoring Project. The previous editions of the science page are available on our website.
The Science Page this week is a collaboration between the University of Alberta and Hendrix Genetics regarding low litter birth weight phenotypes in sows.
- In every herd there is a population of sows that produce low birth weight piglets independent of the litter size
- The litter birth weight phenotype (LBWP) is a sow-related phenotype
- Low LBWP sows show delayed embryonic and placental development on day 30 of gestation
