| Abstract: | A total of 88 thoroughbred mares were diagnosed with clinical ovarian quiescence andsubjected to four treatment regimens. Using PMSG, hCG or combinations of both. A high dosecombination of 5,000IU PMSG with 5,000IU hCG showed significantly higher rates of markedestrus and ovulation induction (P<0.01) as well as conception rates (P<0.05). In thepresent study, the administration of a high-dose combination of PMSG with hCG was shown tobe an effective treatment of ovarian quiescence in light mares. |
