Thus, the use of biosensors\n                    provides more opportunities for artificial insemination because it is easier to\n                    confirm estrus than by visual observation. This study determines the accuracy of\n                    estrus prediction using a ruminoreticular biosensor by analyzing ruminoreticular\n                    temperature during the estrus cycle and measuring changes in body activity. One\n                    hundred and twenty-five Hanwoo cows (64 with a ruminal biosensor in the test\n                    group and 61 without biosensors in the control group) were studied.\n                    Ruminoreticular temperatures and body activities were measured every 10 min. The\n                    first service of artificial insemination used gonadotropin-releasing hormone\n                    (GnRH)-based fixed-time artificial insemination protocol in the control and test\n                    groups. The test group received artificial insemination based on the estrus\n                    prediction made by the biosensor, and the control group received artificial\n                    insemination according to visual estrus observation. Before artificial\n                    insemination, the ruminoreticular temperature was maintained at an average of\n                    38.95 \u00b1 0.05\u00b0C for 13 h (\u221221 to \u22129 h), 0.73\u00b0C\n                    higher than the average temperature observed at \u221248 h (38.22 \u00b1\n                    0.06\u00b0C). The body activity, measured using an indwelling 3-axis\n                    accelerometer, averaged 1502.57 \u00b1 27.35 for approximately 21 h from\n                    \u22124 to \u221224 h before artificial insemination, showing 203 indexes\n                    higher body activity than \u221248 hours (1299 \u00b1 9.72). Therefore,\n                    using an information and communication techonology (ICT)-based biosensor is\n                    highly effective because it can reduce the reproductive cost of a farm by\n                    accurately detecting estrus and increasing the rate of estrus confirmation in\n                    cattle.<\/jats:p>","DOI":"10.5187\/jast.2022.e125","type":"journal-article","created":{"date-parts":[[2023,1,18]],"date-time":"2023-01-18T03:31:36Z","timestamp":1674012696000},"page":"759-766","update-policy":"https:\/\/doi.org\/10.5187\/crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Increased accuracy of estrus prediction using ruminoreticular\n                    biocapsule sensors in Hanwoo (Bos taurus coreanae)\n                    cows"],"prefix":"10.5187","volume":"65","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4820-4438","authenticated-orcid":false,"given":"Daehyun","family":"Kim","sequence":"first","affiliation":[{"name":"Livestock Research Institute, Yeongju 36052, 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":[{"id":[{"id":"https:\/\/ror.org\/040c17130","id-type":"ROR","asserted-by":"publisher"}],"name":"Department of Animal Science and Biotechnology, Kyungpook National University, Sangju 37224, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6785-6346","authenticated-orcid":false,"given":"Jaejung","family":"Ha","sequence":"additional","affiliation":[{"name":"Livestock Research Institute, Yeongju 36052, 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":"GenNBio Co., Ltd., Pyeongtaek 17792, 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, Yeongju 36052, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"3132","published-online":{"date-parts":[[2023,7,30]]},"reference":[{"key":"key2.0261002112811e+13_B1","doi-asserted-by":"crossref","first-page":"90","DOI":"10.1016\/j.theriogenology.2018.09.038","article-title":"Estrous detection by continuous measurements of vaginal\n                        temperature and conductivity with supervised machine learning in\n                        cattle","volume":"123","author":"Higaki","year":"2019","journal-title":"Theriogenology."},{"key":"key2.0261002112811e+13_B2","doi-asserted-by":"crossref","first-page":"925","DOI":"10.1016\/j.theriogenology.2014.01.009","article-title":"Infrared technology for estrus detection and as a predictor of\n                        time of ovulation in dairy cows in a pasture-based system","volume":"81","author":"Talukder","year":"2014","journal-title":"Theriogenology."},{"key":"key2.0261002112811e+13_B3","doi-asserted-by":"crossref","first-page":"335","DOI":"10.1016\/j.cvfa.2016.01.006","article-title":"Synchronization and artificial insemination strategies in beef\n                        cattle","volume":"32","author":"Lamb","year":"2016","journal-title":"Vet Clin North Am Food Anim Pract."},{"key":"key2.0261002112811e+13_B4","doi-asserted-by":"crossref","first-page":"4404","DOI":"10.3168\/jds.2009-2789","article-title":"Economic comparison of natural service and timed artificial\n                        insemination breeding programs in dairy cattle","volume":"93","author":"Lima","year":"2010","journal-title":"J Dairy Sci."},{"key":"key2.0261002112811e+13_B5","doi-asserted-by":"crossref","first-page":"50","DOI":"10.1136\/vr.91.3.50","article-title":"A study of oestrous behaviour and oestrus detection methods in a\n                        large commercial dairy herd.
