La présente étude a été conçue pour étudier les effets des injections de PGF2α ou de GnRH pendant le post-partum sur l’involution utérine, la durée de la période post-partum, le nombre de saillies par conception, les jours d’ouverture et l’intervalle de vêlage chez les vaches laitières soudanaises de race croisée.Les résultats de cette expérience expliquent que l’injection de GnRH raccourcit significativement le temps nécessaire à l’involution utérine, la période post-partum, les jours d’ouverture et l’intervalle entre les vêlages par rapport au contrôle (P < 0,005, p < 0,05, P < 0,001 et P < 0,001 respectivement). En outre, le nombre de services par conception a été amélioré de manière significative (P < 0,04).Il est conclu que l’utilisation de PGF2α ou de GnRH pendant la première, la deuxième ou la troisième semaine du post-partum améliore l’efficacité de la reproduction des vaches laitières croisées. Ainsi, un veau par vache et par an peut être produit si ce régime est utilisé. Cependant, une injection unique de PGF2α dès 7 jours n’a aucun effet sur les paramètres susmentionnés.
