Ovarian response to porcine FSH in association with ablation-induced or spontaneous follicular wave development during the estrous cycle in crossbred and Brazilian Warmblood mares (original) (raw)

The primary objective of this study was to examine the follicular and ovulatory responses following treatment with porcine FSH (pFSH) in association with ablation-induced or spontaneous follicular wave emergence during the estrous cycle in crossbred and Brazilian Warmblood mares. Three experiments were conducted, assessing the effectiveness of pFSH and comparing it to control treatments. The results indicated that using follicle ablation prior to pFSH treatment did not enhance follicular or ovulatory responses compared to controls in crossbred mares. Furthermore, Brazilian Warmblood mares did not show improved responsiveness to pFSH compared to EPE. Overall, the findings support the notion that pFSH is generally ineffective for follicular superstimulation in mares.
