Abstract

The syringe and oocyte recovery unit designed for the human ovary was modified for the bovine ovary. From a local slaughterhouse, ten Holsteins and 7 Herefords were selected for experimental purposes. The recovery of 70 ova required aspirating 228 follicles for an overall recovery rate of 30.7%. There was no difference in the results obtained by using the syringe aspiration only or by using the modified ova recovery unit. The recovery results of the Hoslstein oocytes compared with the Hereford and of the small follicles compared with the large were approximately the same.
