pubmed-article:19329807 | pubmed:abstractText | The gait scoring system developed by Manson and Leaver was used by five experienced observers to assess the gait of 83 milking Holstein-Friesian cows in a live recording session, and video recordings were made. The agreement between the scores of the observers at the live session, and between each observer's scores at the live session and a video session, were compared at three levels of stringency. The scores of the observers were highly variable at all but the least stringent threshold - whether a cow had a score of less than 3 or 3 or more, that is, whether it was not lame or lame. | lld:pubmed |
