La d\u00e9tection des chaleurs n\u2019est pas une sin\u00e9cure, surtout en stabulation entrav\u00e9e. Elle constitue sans doute un des facteurs majeurs d\u2019infertilit\u00e9. La sensibilit\u00e9 d\u2019une d\u00e9tection des signes comportementaux est comprise entre 50 et 60 %. La sensibilit\u00e9 des podom\u00e8tres et des acc\u00e9l\u00e9rom\u00e8tres varient selon la production laiti\u00e8re (36 \u00e0 68 %) et l\u2019environnement (p\u00e2tures vs logettes\u00a0: 69 vs 37 %). Par ailleurs ces m\u00e9thodes sont peu utilisables en stabulation entrav\u00e9e. Des chercheurs japonais (Higaki et al. Theriogenology 2019, 123,90-99) ont enregistr\u00e9 en continu les temp\u00e9ratures et les conductivit\u00e9s vaginales de 17 vaches en stabulation entrav\u00e9e (Mattias Andersson et al. Computers and Electronics in Agriculture<\/a>, 2016, 127, 101-108\u00a0; Voir figure). Ils ont par ailleurs soumis les animaux \u00e0 un suivi \u00e9chographique, hormonal et comportemental. Ces donn\u00e9es ont \u00e9t\u00e9 analys\u00e9es au moyen d\u2019algorithmes sp\u00e9cifiques.<\/p>\n

Cette recherche ouvre de nouvelles perspectives dans la compr\u00e9hension de la physiologie de la reproduction et dans la d\u00e9tection de l\u2019\u0153strus et donc du choix du moment optimal de l\u2019ins\u00e9mination.<\/p>\n<\/div>
