Produção in vitro de embriões em pequenos ruminantes

Abstract

This paper reviews the technical bases of in vitro embryo production in small ruminants with special attention to the results obtained by our group in Northeastern Brazil. The laparoscopic oocyte recovery in hormonally treated live animals indicates a promising future for the application of this technique to genetic improvement program. New molecular biology tools should provide information to improve the efficiency of in vitro maturation. Furthers efforts have to be made to improve the oocyte maturation and to standardize the semen-capacitating process. © 2010 Sociedade Brasileira de Zootecnia.
