The aim of this study was to evaluate if GnRH incorporation to the hCG treatment improves the reproductive parameters of seasonal anestrous goats in northern Mexico (26°N). Adult anovulatory adult (n = 36) were divided into 4 groups (n = 9), according to live weight and body condition score. On May 2, all goats were treated with progesterone (20 mg) intramuscular (im). Twenty-four hours before (d 0), Gc was treated with physiological saline (0.5 mL), Gh with hCG im (100 IU), G3 with hCG (100 IU) + GnRH (8.4 μg), and G4 with hCG (100 UI) + GnRH (8.4 μg) 24 h before hCG administration. The same day, all goats received PGF2α (7.5 mg) intravenously. Estrous was determined twice a day, from d-0 to d-5, using multiracial bucks provided with an apron; females were considered to be in estrus when allowed to be mounted. To determine ovulation occurrence, a transrectal ultrasonographic scanning (US) (Aloka SSD 500, Richmond, BC, Canada) was performed on d-10 in all goat; ovulation considered the presence of well defined corpus luteum at either ovary. Chi-squared test was performed to determine the differences among all groups concerning the reproductive traits measured (SYSTAT, Version 10, 2006), with a 95% interval confidence. The Gc group had no response in estrus, ovulation and gestation (0%, 0/9). The Gh-group had the highest percentages (P < 0.05) of both estrus (88.8%, 8/9) and pregnancy (71.4%, 5/9) and, along with G4, the highest ovulating rate (55.5%, 5/9). Results suggest that GnRH inclusion at moment or 24-h before hCG treatment negatively affects the reproductive outcomes of seasonally anestrous goats.
