Impact of fermented Broussonetia papyrifera on laying performance, egg quality, lipid metabolism, and follicular development of laying hens

Poultry Science, 2023
: Hybrid Broussonetia papyrifera (BP) has been widely planted and commonly used as ruminant forage source after fermentation in China. Very less information is available to know the impact of fermented BP on laying hens, thus, we have investigated ...

Role of RGMc as a Neogenin Ligand in Follicular Development in the Ovary

Biomedicines, 2021
There is currently no cure for infertility in women with a poor ovarian response (POR). Neogenin is reported to be abundantly expressed in the ovary; however, its role in mammalian follicular development is unclear and its ligand and signaling pathway ...

Muscarinic receptors in the rat ovary are involved in follicular development but not in steroid secretion

Physiological Reports, 2022
Acetylcholine (ACh) may be involved in the regulation of ovarian functions. A previous systemic study in rats showed that a 4‐week, intrabursal local delivery of the ACh‐esterase blocker Huperzine‐A increased intraovarian ACh levels and changed ovarian ...

The role of oestrogen in follicular development [PDF]

Molecular Human Reproduction, 1997
Most of our knowledge of ovarian physiology is based upon studies that have demonstrated functional oestrogen receptors in the ovaries of lower animal species. The presence of oestrogen receptors in primate granulosa cells has been questioned by some investigators.

An efficient protocol for inducing pseudopregnancy using estradiol dipropionate and follicular development associated with changes in reproductive hormones after prostaglandin F2alpha treatment in pseudopregnant sows

Reproductive Biology and Endocrinology, 2011
Background Utilization of estrus synchronization program in livestock industry would provide greater options for reproductive management in herd. To develop a convenient method for estrus synchronization in pigs, we determined the effective protocol ...

Effects of hypercaloric diet-induced hyperinsulinemia and hyperlipidemia on the ovarian follicular development in mice

The Journal of Reproduction and Development, 2022
Long-term hypercaloric diets may adversely affect the development of ovarian follicles. We investigated the effects of high sugar (HS), high fat low sugar (HFLS), and high fat normal sugar (HFNS) diets on the ovarian follicle development in mice fed with

FERTILIZATION AND DEVELOPMENT OF PIG FOLLICULAR OOCYTES [PDF]

Reproduction, 1971
The capacity of follicular oocytes for normal fertilization has been tested in hamsters (Barros & Austin, 1967), sheep (Woody, Alliston & Ulberg, 1961) and rabbits (Noyes, 1952; Chang, 1955). Follicular oocytes of rabbits and hamsters were fertilized at a reduced rate but no sheep oocytes developed.
