Selection of the dominant follicle (DF) during a follicular wave is manifested by diameter
deviation or continued growth rate of the largest follicle (F1) and decreased growth rate of …

Initial studies of the ovaries were based on postmortem anatomic descriptions, followed by
histologic and endocrine approaches. The introduction of high-resolution ultrasonography …

Our objective was to determine the effect of inducing an accessory corpus luteum (CL) with
human chorionic gonadotropin (hCG; 3,300 IU) on d 7 (hCG7) or 2 accessory CL with hCG …

The objectives of this prospective cohort study were to characterize associations among
genomic merit for fertility with ovarian and endocrine function and the estrous behavior of …

Precision dairy farming technologies have tremendous potential to improve and support
farmers in herd management decisions, particularly in reproductive management …

This chapter provides an overview of our present understanding of ovarian function in cattle,
with emphasis on the dynamics and control of follicular and luteal gland development. It is …

Granulosa cell proliferation and differentiation are key developmental steps involved in the
formation of the dominant follicle eligible for ovulation. This process is, in turn, regulated by …

An understanding of the normal estrous-cycle length of the cow is important when managing
and monitoring dairy-herd fertility. Although the normal interovulatory interval is widely …

Ovarian follicular dynamics was monitored by transrectal ultrasonography, for a period of 60
to 90 days, and its correlation with plasma estradiol-17β (E2) and progesterone (P4) were …

Background We tested the hypothesis that organelles in bovine oocytes undergo changes in
number and spatial distribution in a manner specific for phase of follicle development …
