Changes in body temperature such as ruminal, rectal, and vaginal temperature during the parturition have been reported, but there are no results of the simultaneous observation of body temperature and activity. The aim of this study was to simultaneously confirm changes in the ruminoreticular temperature and body activity before and after parturition using the ruminoreticular bio-capsule sensor every 1 h. The 55 pregnant cows were used for the experiment, the ruminoreticular bio-capsule sensor was inserted and stabilized, and the ruminoreticular temperature and body activity were measured. The ruminoreticular temperature was lower by 0.5\u00b0 from \u221224 h to \u22123 h in parturition compared to 48 h before parturition and then recovered again after parturition. Body activity increased temporarily at the time of parturition and 12 h after parturition. Therefore, the ruminoreticular temperature and body activity before and after parturition was simultaneously confirmed in pregnant cows.<\/jats:p>","DOI":"10.3390\/s21237892","type":"journal-article","created":{"date-parts":[[2021,12,1]],"date-time":"2021-12-01T01:45:02Z","timestamp":1638323102000},"page":"7892","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Change of Ruminoreticular Temperature and Body Activity before and after Parturition in Hanwoo (Bos taurus coreanae) Cows"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4820-4438","authenticated-orcid":false,"given":"Daehyun","family":"Kim","sequence":"first","affiliation":[{"name":"Livestock Research Institute, 186 Daeryongsan-ro, Anjeong-Myeon, Yeongju 36052, Gyeongsangbuk-do, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jaejung","family":"Ha","sequence":"additional","affiliation":[{"name":"Livestock Research Institute, 186 Daeryongsan-ro, Anjeong-Myeon, Yeongju 36052, Gyeongsangbuk-do, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0848-7189","authenticated-orcid":false,"given":"Woo-Sung","family":"Kwon","sequence":"additional","affiliation":[{"name":"Department of Animal Science and Biotechnology, Kyungpook National University, Sangju 41566, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6513-557X","authenticated-orcid":false,"given":"Joonho","family":"Moon","sequence":"additional","affiliation":[{"name":"Lartbio Co., Ltd., 12 Floor, 234 Teheran-ro, Gangnam-gu, Seoul 06221, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gyeong-Min","family":"Gim","sequence":"additional","affiliation":[{"name":"Laboratory of Theriogenology and Biotechnology, Department of Veterinary Clinical Sciences, College of Veterinary Medicine, Seoul National University, 1 Gwanak-ro, Gwanak-gu, Seoul 08826, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2593-6529","authenticated-orcid":false,"given":"Junkoo","family":"Yi","sequence":"additional","affiliation":[{"name":"Livestock Research Institute, 186 Daeryongsan-ro, Anjeong-Myeon, Yeongju 36052, Gyeongsangbuk-do, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,11,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"273","DOI":"10.1111\/jpn.12249","article-title":"Continuous measurement of reticuloruminal pH values in dairy cows during the transition period from barn to pasture feeding using an indwelling wireless data transmitting unit","volume":"99","author":"Gasteiner","year":"2015","journal-title":"J.
