In-vitro developmental potential of bovine oocytes obtained by transvaginal follicular aspiration as related to their morphological quality and after microinjection of DNA
The development of oocytes of differing quality retrieved using transvaginal follicular aspiration (TVFA) and following DNA injection was examined. Eight cows were subjected to twice weekly TVF A for 16 wk. Oocytes retrieved were graded and placed in an in-vitro maturation, fertilization and …
