Selection of the dominant follicle in cattle and horses

Animal Reproduction Science, 2000
The nature of selection of the dominant follicle is reviewed by comparing research results between cattle and horses. In both species, emergence of a follicular wave is stimulated by an FSH surge. The surge reaches a peak by the time the follicles attain 4 mm in diameter in cattle and 13 mm in mares.

Complexities of follicle deviation during selection of a dominant follicle in Bos taurus heifers

Theriogenology, 2016
Follicle deviation during a follicular wave is a continuation in growth rate of the dominant follicle (F1) and decreased growth rate of the largest subordinate follicle (F2). The reliability of using an F1 of 8.5 mm to represent the beginning of expected deviation for experimental purposes during waves 1 and 2 (n = 26 per wave) was studied daily in ...

Oocyte morphology in dominant and subordinate follicles

Molecular Reproduction and Development, 1994
AbstractThe structure of oocytes aspirated from the dominant and its subordinate follicles was investigated from the achievement of follicular dominance to ovulation. Ovulation was induced in 18 heifers and 5 cows by injection of cloprostenol at days 8–14 (day 0 = day of ovulation), and follicular development was monitored by ultrasonography.

Managing the dominant follicle in lactating dairy cows

Theriogenology, 2011
Reproductive efficiency is not optimal in high-producing dairy cows. Although many aspects of ovarian follicular growth in cows are similar to those observed in heifers, there are numerous specific differences in follicular development that may be linked with changes in reproductive physiology in high-producing lactating dairy cows.

Characteristics of developing prolonged dominant follicles in cattle

Domestic Animal Endocrinology, 2003
In cattle, sub-luteal circulating progesterone induces an increase in the frequency of LH pulses, prolonged growth of the dominant follicle, increased peripheral estradiol and reduced fertility. The objective of this study was to examine the earliest stages of development of prolonged dominant follicles, to gain insight into the etiology of this ...
