The oocyte donor plays a pivotal role in bovine in vitro embryo production (IVP) success. The individual factor affects blastocyst/oocyte ratio and determine the existence of outstanding performing animals. The aim of this study was to assess the extent of individual factor effect to IVP efficiency, in a population of Gir oocyte donors. Extreme (high or low IVP efficiency based on blastocyst/oocyte ratio) animals were selected out of a population of 250 oocyte donors (1,734 observations) to form high (>0.48, n = 40), average (0.17-0.48, n = 168), and low (<0.17, n = 42) efficiency donor groups. Cumulus-oocyte complex indicators (total number, IVF-grade number, and IVF-grade/total ratio) were lower (p < 0.05) in high efficiency donors. The number of blastocysts per OPU was analyzed for highest performing bull, and an increase (p < 0.05) in high efficiency donors and a decrease (p < 0.05) in low efficiency donors were noticed, compared to average efficiency donors. The number of pregnancies obtained per OPU was affected (p = 0.017) by donor?s efficiency (low: 0:600:09, average: 1:170:07, high: 2:570:26), being 4.3-fold higher in high than in low efficiency donors. We conclude that producing embryos from high efficiency blastocyst/oocyte ratio donors increases blastocyst and pregnancy numbers by OPU, being an important indicator for donor selection in IVP programs |
