The objective of this study was to evaluate in <em>Bos taurus indicus</em> heifers the effect of FSH incorporated in Pluronic<sup>®</sup> F127 on the quality of oocytes collected by follicular aspiration. A total of 30 cyclic Brahman heifers were selected and assigned into one of three experimental groups (control group, FSH-SC and FSH-PF127). Heifers in the FSH-SC group received a single dose of 50 mg FSH subcutaneously and heifers in the FSH-PF127 group were treated with 50 mg FSH incorporated in Pluronic<sup>®</sup> F127. The rate of viable oocytes was higher for the FSH-PF127 group compared to the control and FSH-SC groups. The administration of a single dose of 50 mg of FSH in Pluronic<sup>®</sup> F127 influenced the oocyte quality and the rate of viable oocytes of Brahman breed heifers.</p> ER -
