Reproductive performance, body surface and eye temperature (ET) were evaluated as sows\u2019 welfare indicators. A sample of 56 sows between 2nd and 6th parity was submitted to the treatments from artificial insemination to weaning. The sows were assigned in a randomized block design with a 2 \u00d7 2 factorial scheme of treatments: mixed housing\u2014control (MH-C), collective housing\u2014control (CH-C), mixed housing\u2014music (MH-M) and collective housing\u2014music (CH-M). Auditory enrichment consisted of exposing sows daily throughout gestation and lactation to 6 h of classical music divided into 2 h periods. The ET of pregnant sows in collective housing was lower than that of sows in mixed housing (33.77 \u00b0C vs. 34.91 \u00b0C). Pregnant and lactating sows exposed to auditory environmental enrichment exhibited lower ET compared to those that had no access to the stimulus (pregnant 33.36 \u00b0C vs. 34.32 \u00b0C and lactating 34.21 \u00b0C vs. 34.83 \u00b0C). No housing type effect was found on the reproductive performance parameter; however, piglets from sows submitted to auditory environmental enrichment, regardless of the type of housing during gestation, were heavier at weaning (6.32 kg vs. 5.57 kg). Collective or mixed housing does not affect sows\u2019 reproductive performance; perhaps, auditory environmental enrichment reduced stress in the gestation and lactation phases and provided greater piglet weight gain at weaning.<\/jats:p>","DOI":"10.3390\/ani13071226","type":"journal-article","created":{"date-parts":[[2023,3,31]],"date-time":"2023-03-31T10:19:33Z","timestamp":1680257973000},"page":"1226","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Performance and Welfare of Sows Exposed to Auditory Environmental Enrichment in Mixed or Collective Housing Systems"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7860-0933","authenticated-orcid":false,"given":"Janaina","family":"Palermo Mendes","sequence":"first","affiliation":[{"name":"Animal Science Postgraduate Program, Agricultural Sciences, Federal University of Grande Dourados (UFGD), Dourados 79804-970, MS, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7564-6127","authenticated-orcid":false,"given":"Fabiana","family":"Ribeiro Caldara","sequence":"additional","affiliation":[{"name":"Animal Science Postgraduate Program, Agricultural Sciences, Federal University of Grande Dourados (UFGD), Dourados 79804-970, MS, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8079-2890","authenticated-orcid":false,"given":"Maria Fernanda","family":"de Castro Burbarelli","sequence":"additional","affiliation":[{"name":"Animal Science Postgraduate Program, Agricultural Sciences, Federal University of Grande Dourados (UFGD), Dourados 79804-970, MS, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8547-4149","authenticated-orcid":false,"given":"Jean Kaique","family":"Valentim","sequence":"additional","affiliation":[{"name":"Animal Science Postgraduate Program, Agricultural Sciences, Federal University of Grande Dourados (UFGD), Dourados 79804-970, MS, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniela","family":"Ferreira de Brito Mand\u00fa","sequence":"additional","affiliation":[{"name":"Animal Science Postgraduate Program, Agricultural Sciences, Federal University of Grande Dourados (UFGD), Dourados 79804-970, MS, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4978-9386","authenticated-orcid":false,"given":"Rodrigo","family":"Gar\u00f3fallo Garcia","sequence":"additional","affiliation":[{"name":"Animal Science Postgraduate Program, Agricultural Sciences, Federal University of Grande Dourados (UFGD), Dourados 79804-970, MS, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ibiara","family":"Correia de Lima Almeida-Paz","sequence":"additional","affiliation":[{"name":"Department of Animal Production, School of Veterinary Medicine and Animal Science (FMVZ), S\u00e3o Paulo State University (UNESP), Botucatu 18610-034, SP, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0413-5610","authenticated-orcid":false,"given":"Agnes","family":"Markiy Odakura","sequence":"additional","affiliation":[{"name":"Animal Science Postgraduate Program, Agricultural Sciences, Federal University of Grande Dourados (UFGD), Dourados 79804-970, MS, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3636-4805","authenticated-orcid":false,"given":"Marconi Italo","family":"Louren\u00e7o da Silva","sequence":"additional","affiliation":[{"name":"Department of Animal Production, School of Veterinary Medicine and Animal Science (FMVZ), S\u00e3o Paulo State University (UNESP), Botucatu 18610-034, SP, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,3,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Sardi, L., Gastaldo, A., Borciani, M., Bertolini, A., Musi, V., Martelli, G., Cavallini, D., Rubini, G., and Nannoni, E.
