L’anœstrus de type III (Kyste folliculaire et kyste folliculaire lutéinisé)

Caractéristiques
→ Persistance d’une structure de grande taille (d≥25mm)
→ Kyste folliculaire si paroi du kyste fine (<2mm, non visible à l’échographie) ou kyste folliculaire lutéinisé si paroi du kyste épaisse (2-5mm, visible à l’échographe)
→ Pas de corps jaune

Objectif du traitement
→ Kyste folliculaire :
Lutéiniser le kyste folliculaire, puis provoquer la lyse du kyste lutéal induit
Ou : faire régresser le kyste tout en démarrant une nouvelle vague folliculaire
→  Kyste folliculaire lutéinisé :
Provoquer la lyse du kyste

Traitement
La GnRH seule donne des résultats décevants (Veronesi M.C. et al., 2003, Jou P. et al.
1999). Elle n’améliore

→  ni le délai de retour en chaleurs
→  ni le pourcentage d’oestrus observés dans les 30j
→  ni le taux de gestation

La reprise d’un état corporel suffisant est primordiale à la réussite du traitement (3,6
fois plus de chances).
