| ABSTRACT The success of transvaginal follicular aspiration in mares can be influenced by several factors, such as vacuum pump pressure levels. The present study aimed to investigate the effect of different negative pressures (150, 280 and 400mmHg) of the vacuum pump on the oocyte recovery in the mares. The mares (n=10) were undergoing follicular aspiration using three different negative pressures for three consecutive estrous cycles as follows: G150 = 150mmHg (n = 10); G280 = 280mmHg (n = 10); G400 = 400mmHg (n = 10). Every estrous cycle, the group that the mare would participate was drawn, and each animal participated once in each group. Only preovulatory follicle was used, about 30 to 36 hours after application of hCG. To compare the results, the... |

| Background Prolactin (PRL) regulates development and reproduction, and its effects are mediated by the prolactin receptor (PRLR). In order to clarify the role of PRLR and PRL in the process of follicular development in the goose ovary, the level of PRLR mRNA expression in the ovary and follicles of the Sichuan white goose was determined, as well as the PRL concentration in ovarian follicles. Results The level of PRLR mRNA in the hierarchical follicles (HFs) initially increased, and subsequently decreased, whereas PRLR expression was initially low and later increased in postovulatory follicles (POFs). The level of PRLR mRNA expression was the highest in the F4 follicles, and lowest in the F1 follicles in all of the examined follicles. Compared with the... |
