Therefore, this experiment was performed to compare the effects of individual stalls (IS) and group housing systems (GS) on the productivity of sows to investigate the feasibility of replacing individual stalls with group housing systems in commercial sow units. Forty primiparous sows (Landrace \u00d7 Yorkshire; 210.67 \u00b1 2.22 kg average initial body weight) were randomly assigned to four treatments with restricted feeding after 8 weeks from artificial insemination. The four treatments were (i) individual stalls (IS; housed in pen stalls), (ii) short stalls (SS; sows housed in pens with non-gated feeding stalls), (iii) free access stalls (FAS; a non-competitive housing system), and (iv) electronic sow feeders (ESF; used with radio frequency identification technology to allow individual sow management without individual confinement). All sows were transferred to farrowing crates at 110 days of gestation. There were no differences in sow productive performance, reproductive performance, and colostrum composition between IS and GS and among GS. The considered GS did not negatively affect any productivity parameters of primiparous sows compared with IS; the GS could replace IS in commercial sow units.<\/jats:p>","DOI":"10.3390\/ani10111940","type":"journal-article","created":{"date-parts":[[2020,10,22]],"date-time":"2020-10-22T20:51:00Z","timestamp":1603399860000},"page":"1940","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Comparison of the Productivity of Primiparous Sows Housed in Individual Stalls and Group Housing Systems"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3083-1513","authenticated-orcid":false,"given":"Yejin","family":"Min","sequence":"first","affiliation":[{"name":"Rural Development Administration, National Institute of Animal Science, Cheonan 31000, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4710-4731","authenticated-orcid":false,"given":"Yohan","family":"Choi","sequence":"additional","affiliation":[{"name":"Rural Development Administration, National Institute of Animal Science, Cheonan 31000, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1935-2132","authenticated-orcid":false,"given":"Joeun","family":"Kim","sequence":"additional","affiliation":[{"name":"Rural Development Administration, National Institute of Animal Science, Cheonan 31000, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2392-5535","authenticated-orcid":false,"given":"Doowan","family":"Kim","sequence":"additional","affiliation":[{"name":"Rural Development Administration, National Institute of Animal Science, Cheonan 31000, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1985-583X","authenticated-orcid":false,"given":"Yongdae","family":"Jeong","sequence":"additional","affiliation":[{"name":"Rural Development Administration, National Institute of Animal Science, Cheonan 31000, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9850-8894","authenticated-orcid":false,"given":"Younghwa","family":"Kim","sequence":"additional","affiliation":[{"name":"Rural Development Administration, National Institute of Animal Science, Cheonan 31000, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Minho","family":"Song","sequence":"additional","affiliation":[{"name":"Division of Animal and Dairy Science, Chungnam National University, Daejeon 34134, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hyunjung","family":"Jung","sequence":"additional","affiliation":[{"name":"Rural Development Administration, National Institute of Animal Science, Cheonan 31000, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,10,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1071\/AR00057","article-title":"A review of the welfare issues for sows and piglets in relation to housing","volume":"52","author":"Barnett","year":"2001","journal-title":"Aust.
