Characteristics predictive of a 2-wave versus 3-wave pattern of ovarian follicular
development during the interovulatory interval (IOI) were examined by ultrasonographic …

For 18 two-wave interovulatory intervals in heifers, the follicular waves were first detected on
Days− 0· 2±0· 1 and 9· 6±0· 2, and for 4 three-wave intervals on Days− 0· 5±0· 3, 9· 0±0· 0 …

The two-wave hypothesis for follicular development during the bovine estrous cycle was
tested by ultrasonically monitoring individual follicles in 10 heifers during an interovulatory …

It is not clear whether the turnover of ovarian follicles during the estrous cycle in cattle is
continuous and independent of the phase of the cycle, or whether waves of follicular growth …

Two hypotheses were tested:(1) a dominant follicle causes regression of its subordinate
follicles, and (2) a dominant follicle during its growing phase suppresses the emergence of …

The characteristics of anovulatory and ovulatory follicular waves for 18 interovulatory
intervals with two waves were studied in Holstein heifers. Daily ultrasonic monitoring of …

Daily ultrasonic monitoring of individual follicles was used to compare follicular wave
characteristics of nonbred (n= 6) and pregnant heifers (n= 6). The dominant follicle of the first …

The study of follicular dynamics began in the mid-20th century, but progress has been
particularly rapid in the last two decades through the use of tools that have enabled serial …

In this study, the characteristics of ovarian follicular waves and patterns of serum
concentrations of follicle-stimulating hormone (FSH), estradiol, and progesterone were …

A few days after the first follicular wave emerges as 4-mm follicles, follicular deviation occurs
wherein 1 follicle of the wave continues to grow (dominant follicle) while the others regress …
