Summary: Abstract: This study checked the effectiveness of ranking the difficulty to clip/traction and traverse the cervix with the Hegar dilator as a predictor method for selecting suitable animals to undergo NSER. A total of 46 pluriparous Santa Inês received intravaginal sponges containing 60 mg medroxyprogesterone (Progespon®, Syntex, Buenos Aires, Argentina) during six days plus 200 IU eCG (Novormon 5000®, Syntex, Buenos Aires, Argentina) i.m. and 37.5 ?g d-cloprostenol (Prolise®, ARSA S.R.L., Buenos Aires, Argentina) latero-vulvar 24 h before sponge removal. This grading system may indicate the probability of individual animals to successfully proceed with NSER. It is suggested that a selective system for donors should include an attempt to clip/traction/traverse the cervix, ranking the difficulty of the process, before starting a MOET/NSER protocol. Animals that receive scores 4 and 5 could be excluded from the protocol in order to prevent the use of unable or laborious animals, avoiding wasting resources.
