Effect of elevating luteinizing hormone action using low doses of human chorionic gonadotropin on double ovulation, follicle dynamics, and circulating follicle-stimulating hormone in lactating dairy cows

Journal of Dairy Science, 2022
: Double ovulation and twin pregnancy are undesirable traits in dairy cattle. Based on previous physiological observations, we tested the hypothesis that increased LH action [low-dose human chorionic gonadotropin (hCG)] before the expected time of ...

Understanding the Ovarian Interrelationship with Low Antral Follicle Counts (AFC) in the In Vivo Bos indicus Cow Model: Unilateral and Bilateral Main AFC as Possible Biomarkers of Ovarian Response to Hormonal Synchronisation

Biology, 2022
The antral follicle count (AFC) is a test in which the number of oocyte-containing follicles that are developing in both ovaries are visually counted. The count of these follicles strongly relates to the population of the growing follicle reserve on the ...

Quantitative analyses of insulin-like peptide 3 and sex steroid hormones in dominant follicles and corpora lutea during the estrus cycle and in follicular cysts in beef heifers

The Journal of Reproduction and Development, 2022
Insulin-like peptide 3 (INSL3) and sex steroids were measured in bovine dominant follicles and corpora lutea during the estrus cycle and in follicular cysts.

Attaining dominance in vivo: distinguishing dominant from challenger follicles in humans [PDF]

Human Reproduction, 1997
This study provides the first report of local suppression of follicle growth in vivo by the dominant follicle in humans. Analyses were focused on antral follicles > or =6 mm in diameter, classified as dominant (ovulatory) and challenger (large, non-ovulatory) follicles. We examined antral follicle characteristics, interactions and location in the ovary

Uterine and systemic inflammation influences ovarian follicular function in postpartum dairy cows. [PDF]

PLoS ONE, 2017
The objective of this study was to determine the effects of uterine and systemic inflammatory responses to uterine bacterial contamination at calving in dairy cows on the growth and ovulatory outcomes of the first dominant follicle postpartum.

Prediction of Ovarian Follicular Dominance by MRI Phenotyping of Hormonally Induced Vascular Remodeling

Frontiers in Medicine, 2021
In the mammalian female, only a small subset of ovarian follicles, known as the dominant follicles (DFs), are selected for ovulation in each reproductive cycle, while the majority of the follicles and their resident oocytes are destined for elimination ...

Histomorphometry of dominant and subordinate bovine ovarian follicles [PDF]

The Anatomical Record, 2000
The study was designed to quantitatively characterize the histomorphological attributes of dominant and subordinate follicles in relation to follicular wave dynamics. Heifers (n = 27) were examined daily using ultrasonography to record the growth of individual follicles from 2 days before ovulation until the day of ovariectomy to obtain growing (n = 7),

Comparison of PUFA profiles in the blood and in follicular fluid and its association with follicular dynamics after PGF2α induced luteolysis in dairy cows [PDF]

, 2016
The objectives of the present study were to examine the fatty acid (FA) profiles in serum and in the follicular fluid (FF) and the association between polyunsaturated fatty acid level (PUFA) and follicular growth dynamics following induced luteolysis in ...

Dinâmica folicular em cabras da raça Toggenburg em lactação tratadas ou não com somatotropina bovina recombinante Follicular dynamics of lactating Toggenburg does treated with recombinant bovine somatotropin

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2007
Avaliou-se o efeito da injeção de somatotropina bovina recombinante (r-bST) sobre o ciclo estral de cabras. Foram utilizadas 24 fêmeas da raça Toggenburg, distribuídas em dois tratamentos: T1 (n=12), cabras tratadas com r-bST; e T2 (n=12), cabras ...
