Evaluation of the effects of the recommended oral dose of diflubenzuron on bovine sperm and oocyte quality using CASA and OPU-IVEP.

Introduction: The aim of this study was to evaluate potential effects of diflubenzuron on the production and quality of gametes, and on embryo production (IVEP) outcomes, in cattle.

Methods: Two experiments were performed, the first to evaluate effects on semen, and the second on -oocyte complexes (COC) and on IVEP. Nelore () bulls ( = 14) or heifers ( = 16) were allocated into control (CG) or treatment (DIF) groups.
