Parmi les différentes méthodes d’élevage visant à améliorer le potentiel reproductif, l’insémination artificielle se distingue comme une technique exceptionnellement efficace, en particulier chez les vaches laitières. Ses avantages économiques par rapport à l’accouplement naturel sont considérables ; toutefois, les difficultés liées à la détection précise de l’œstrus limitent son plein potentiel dans les exploitations laitières. Des études ont montré un lien évident entre une détection inadéquate de l’œstrus et une efficacité réduite de la reproduction.Pour améliorer les taux de détection de l’œstrus, des programmes de synchronisation, qui aident à réguler la durée de vie du corps jaune, ont été introduits. Des études récentes ont fait état de l’utilisation de protocoles combinant des hormones pour la synchronisation thérapeutique de l’œstrus chez des vaches laitières en post-partum précoce souffrant de troubles ovariens. Cela souligne la nécessité d’une étude complète des programmes de synchronisation de l’œstrus, en particulier à heure fixe, chez les vaches laitières en post-partum précoce, y compris celles souffrant de troubles ovariens. Une évaluation du protocole Ovsynch pourrait conduire au développement d’un programme de synchronisation plus efficace et plus fiable qui maintiendrait les taux de gestation chez les vaches laitières en post-partum.
