The duration of an increase in steps in <jats:styled-content style=\"fixed-case\">ST<\/jats:styled-content> heat was 11.8\u00a0\u00b1\u00a01.3\u00a0hr, and it was similar to that of <jats:styled-content style=\"fixed-case\">ST<\/jats:styled-content> events (duration: 10.1\u00a0\u00b1\u00a00.8\u00a0hr). Even in silent heat, the change pattern and the duration (11.6\u00a0\u00b1\u00a00.2\u00a0hr) of the period with an increase in steps during estrus were not different compared with <jats:styled-content style=\"fixed-case\">ST<\/jats:styled-content> heat. When artificial insemination (<jats:styled-content style=\"fixed-case\">AI<\/jats:styled-content>) was performed at 15.5\u00a0\u00b1\u00a00.6\u00a0hr from the onset of estrus detected by the pedometer in <jats:styled-content style=\"fixed-case\">ST<\/jats:styled-content> heat cases, the conception rate was 57.1% (8\/14). Furthermore, fertility in cattle that underwent silent heat was evaluated. When <jats:styled-content style=\"fixed-case\">AI<\/jats:styled-content> was performed at 14.4\u00a0\u00b1\u00a02.0\u00a0hr from the onset of estrus detected by the pedometer, the conception rate was 60% (3\/5) in silent heat cases. The overall results suggest that the radiotelemetric pedometer is a valid device for detecting estrus and it can even detect silent heat in Japanese Black cattle. Moreover, even silent heat cattle are fertile when <jats:styled-content style=\"fixed-case\">AI<\/jats:styled-content> is performed at the appropriate time.<\/jats:p>","DOI":"10.1111\/asj.13023","type":"journal-article","created":{"date-parts":[[2018,5,29]],"date-time":"2018-05-29T06:50:17Z","timestamp":1527576617000},"page":"1067-1072","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Efficiency of a pedometer device for detecting estrus in standing heat and silent heat in Japanese Black cattle"],"prefix":"10.1111","volume":"89","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5233-7674","authenticated-orcid":false,"given":"Takuo","family":"Hojo","sequence":"first","affiliation":[{"name":"Livestock and Grassland Research Division Kyushu Okinawa Agricultural Research Center National Agriculture and Food Research Organization (NARO) Kumamoto Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3958-6710","authenticated-orcid":false,"given":"Miki","family":"Sakatani","sequence":"additional","affiliation":[{"name":"Livestock and Grassland Research Division Kyushu Okinawa Agricultural Research Center National Agriculture and Food Research Organization (NARO) Kumamoto Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Naoki","family":"Takenouchi","sequence":"additional","affiliation":[{"name":"Livestock and Grassland Research Division Kyushu Okinawa Agricultural Research Center National Agriculture and Food Research Organization (NARO) Kumamoto Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2018,5,28]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.3168\/jds.S0022-0302(86)80653-1"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.theriogenology.2014.06.010"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.anireprosci.2008.07.001"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.anireprosci.2011.07.014"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.3168\/jds.S0022-0302(98)75758-3"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1136\/vr.99.24.472"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.theriogenology.2008.06.023"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.applanim.2003.12.001"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0093-691X(98)00090-9"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.theriogenology.2004.07.007"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.3168\/jds.S0022-0302(97)76035-1"},{"key":"e_1_2_6_13_1","first-page":"195","article-title":"Timing of AI \u2013 have we been wrong all these years?","volume":"12","author":"Nebel R.
