A team at CDPQ has recently run a project that aims to train and inform producers and those involved in the swine sector on rearing gestating sows housed in groups. Here are four videos produced within that project on four different feeding systems for group-housed sows. These videos are commentated by Sebastien Turcotte, an expert on sow behavior.
