Previous studies carried out in sheep (Chupin et al., 1985) and in goats (Nowshari et al., 1995; Martemucci et al., 1996) have underlined the importance of both FSH and LH to induce a good superovulatory response, but the results on the LH amount necessary to give a higher ovulatory response and embryo production are rather contradictory. The aim of this study was to evaluate, in goats, the effect of 2 different FSH/LH ratios (1:1 vs 2:1) kept constant during the treatment, on ovulatory response and embryo production. Moreover, according to the FSH/LH ratio=2:1,.........
