“…Several of these trials have been conducted in Denmark over the past 20 years, with the results of these studies only been briefly mentioned by others (Amdi et al, 2017;Baxter et al, 2013Baxter et al, , 2020Sørensen et al, 2016;and Thorup, 2015). Most of the Danish studies have only been nationally reviewed and published in Danish (Pedersen & Nielsen, 2017;Rasmussen & Moustsen, 2014;Thorup & Bonnichsen, 2007;Thorup & Lybye, 2012;Thorup & Nielsen, 2017Thorup & Sørensen, 2006;Thorup, 2004Thorup, , 2005Thorup, , 2007Thorup, , 2008Thorup, , 2015, however, they contain valuable data and knowledge of nurse sows and are therefore included in this review. Hopefully, this review will expand upon this information by presenting a more comprehensive summary of results from studies with nurse sows that will be useful to both scientists and producers.…”
