  • Dol e:t e I R.: Dynamics ofthe Follicular Development During PR1D Treatment and Quality of the Following Sexual Cycle in Postpartum Cows

  • Dominant follicles slowly grew during progesterone treatment and they ovulated on the day 3.0 ± 0.63 (2-4) after progesterone intravaginal device (PRID) removal in cows with morphological follicular dominance before PRID insertion (n=6)

  • Dominant follicle that occurred during pg treatment ovulated on the day 5.3 ± 1.26 (5-7) after PRiD removal in cows without morphological follicular dominance before PRID insertion (n=4)

Summary

Introduction

Dol e:t e I R.: Dynamics ofthe Follicular Development During PR1D Treatment and Quality of the Following Sexual Cycle in Postpartum Cows. The progestagen treatment induces estrus with higher levels of the plasma estradiol and more expressive LH peak compared to the 1st spontaneous estrus and longer the 1st sexual cycle with higher levels of the milk or plasma progesterone and lower levels of 13,14 dihydro-15-ketoprostaglandin F2alpha (PGFM) compared to the 1st spontaneous sexual cycle in postpartum cows (T r 0 x eland K e s 1e r 1984; Rut t e r et al.1985;Garcia-Winder etal.1987;Smith etal.1987;Mee etal.1991).Our previous work (D ole Z e 1 et al 1993b) showed slow growth of the dominant ovarian follicles and stagnation of the subordinate follicles during 10 days progesterone intravaginal device application in early postpartum cows. The dominant follicles ovulated on the day 3 and 4 after progesterone treatment in cows with morphological follicular dominance at the term of progesterone intravaginal device insertion. The purpose of the present experiment is to confirm our preliminary results and evaluation of quality of the follicular population using plasma estradiol assay
