res of oocytes qualitatively similar to those produced in vivo. The ovaries were obtained in slaughterhouses in the metropolitan region of São Luis - MA and Recife-PE. It was tested, on 10 replicates, the efficiencyof retinol (RT) and retinoic acid (RA) on the in vitro maturation of oocytes goats, using as parameters thenuclear maturation stage. A significant difference was observed (P <0.05) in the percentage of matured oocyteswhen the MBM method was used (53%) compared to other means, demonstrating an increase in the number ofexpanded oocytes. There was no significant difference (P> 0.05) when compared to percentage of goat oocytesmatured in medium that used the RT and RA. It is possible to suggest that this is an effective strategy that shouldbe adopted to increase in vitro maturation.(AU)
