Objective to evaluate the effect of pre-treatment of recombinant bovine somatotropin (rbST) oncumulus-oocyte complexes (CCOs) recovered from OPUs. Using 12 females bovine race Girolando, which theywere divided into three experimental groups: control 0mg, 250mg and 500mg rbST, applied at 12 day intervals.Then, were made five sessions of Ovum Pick Up (OPU) with the aid of ultrasound, with intervals of 7 days. Thevariables studied were submitted to normality test; normal data and standardized by mathematicaltransformations, were subjected to analysis of variance (ANOVA) or parametric test Student-Newman-Keulstocompare means. Obtained mean and standard deviation of the total pattern CCOs and CCOs viable accordingto the following treatments.So, the pre-treatment rbST not influence both in the proportion of CCOs viable andthe morphological quality of CCOs of bovine female.(AU)
