The aim of this study was to compare the embryo production of indicus\u2013taurus<\/jats:italic> donors with high vs low antral follicle counts obtained by ovum pickup<\/jats:italic>\/in vitro<\/jats:italic> production (OPU<\/jats:styled-content>\/IVP<\/jats:styled-content>) and superovulation (SOV<\/jats:styled-content>)\/embryo collection. Braford females at weaning age (3\/8 N<\/jats:styled-content>elore\u00a0\u00d7\u00a05\/8 Hereford, n\u00a0=\u00a0137, 9\u00a0\u00b1\u00a01\u00a0month old) were subjected to six serial ovarian ultrasonographs and were assigned to two groups according to the number of antral follicles \u22653\u00a0mm as follows: G\u2010High antral follicular count (AFC<\/jats:styled-content>, n\u00a0=\u00a020, mean \u226540 follicles) and G<\/jats:styled-content>\u2010Low AFC<\/jats:styled-content> (n\u00a0=\u00a020, mean \u226410 follicles). When the females (n\u00a0=\u00a040) reached 24\u00a0months of age, they were subjected to both OPU<\/jats:styled-content>\/IVP<\/jats:styled-content> and SOV<\/jats:styled-content>\/embryo collection. The average number of follicles remained highly stable throughout all of the ultrasound evaluations (range 0.90\u20130.92). The mean number of COC<\/jats:styled-content>s recovered (36.90\u00a0\u00b1\u00a013.68 vs 5.80\u00a0\u00b1\u00a03.40) was higher (p\u00a0<\u00a00.05) for females with high AFC<\/jats:styled-content>, resulting in higher (p\u00a0<\u00a00.05) numbers of total embryos among females with high vs low AFC<\/jats:styled-content> (6.10\u00a0\u00b1\u00a04.51 vs 0.55\u00a0\u00b1\u00a00.83). The mean number of embryos per collection was also higher (p\u00a0<\u00a00.05) for G<\/jats:styled-content>\u2010H<\/jats:styled-content>igh vs G<\/jats:styled-content>\u2010L<\/jats:styled-content>ow (6.95\u00a0\u00b1\u00a05.34 vs 1.9\u00a0\u00b1\u00a02.13).
