Litter birth weight phenotype and its influence on embryonic and placental development at day 30 of gestation

The Science Page this week is a collaboration between the University of Alberta and Hendrix Genetics regarding low litter birth weight phenotypes in sows.

Key points

  • 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

Our colleagues in the College of Food, Agricultural and Natural resource Sciences (CFANS) have shared one of their latest projects with the National Hog Farmer readers. They found that adding higher amounts of zinc in the late-gestation diet of sows in both a research and commercial herd increased the survival of smaller piglets until they are weaned.

How much floor space do group housed sows need?

An article from our colleagues in the College of Food, Agricultural and Natural Resource Sciences, and published in the National Hog Farmer explores how much space the sows really need. It is critical to find the right balance between the welfare of the animals and the productivity of the farm.
