Table 1 Recovery efficiency in vitro using a conventional (80 cm Teflon tubing) or an adapted (with 0.25 mL semen straws) aspiration system

From: In vivo collection of follicular fluid and granulosa cells from individual follicles of different diameters in cattle by an adapted ovum pick-up system

  1. a, b, c, dThe means without a common superscript in the same column differed by Tukey’s test (P < 0.05).
  2. 1 The adapted system was used only for 8, 6, and 4 mm follicles.
