The building infrastructure of some laboratories and places that house research animals (vivariums) are quite old and have been suffering natural weathering. The set of research stalls where large animals are kept, especially equine species used in projects in the areas of Surgery, Clinics and Reproduction, is quite deteriorated, with problems in the building, hydraulic and electrical st…
The FMVZ building infrastructure where laboratories are located is very old and has been naturally worn down. Some of the labs present water infiltration points, inappropriate roof with broken plaques, windows consumed by rust, allowing constant vibrations that might interfere on the working of precision devices. Due to an old electric network, problems with energy breakdown happen consta…
The purpose of the present study will be: 1) to evaluate the ovulatory inductors effects on the follicular hemodynamics and plasma LH concentration, 2) to describe the effect of sub-doses of hCG on the functionality of the corpus luteum (CL), and 3) to quantify the expression of angiogenic factors of the CL and the plasma hormonal concentration throughout the luteolysis total and partial.…
A limiting factor of the embryo transfer programs is the number and quality of recipients mares during the breeding season. Protocols of ovulation synchronization show low and/or inconsistent results and acyclic recipients hormonal preparations is not available during the whole breeding season. Follicles >25mm ablation induce the formation of luteum estructure capable of producing concent…

Estrogens and progestins treatments are usually applied to prepare non-cyclic recipient mares for embryo transfer programs. Although standardized protocols for exogenous progestins are already described, there are no studies determining the dose and administration frequency of benzoate estradiol, followed by progestins administration, that produce similar hormone profile to that found in …
Use of ovulation inductors, such as hCG and deslorelin, is a common practice in equine reproduction. LH is a hormone responsible for maturation, ovulation and luteinizing of the dominant follicle and its plasmatic concentrations might be related with follicle's walls irrigation. The present study will have as main objective to evaluate the alterations in blood perfusion of dominant follic…
The purpose of the present study will be: 1) to describe the expression of angiogenic factors of the corpus luteum (CL) and the plasma hormonal concentration throughout the luteolysis (total and partial) and during the post-luteolytic and CL resurging phases in mares, and 2) to evaluate the vascular perfusion, secretory function and lifespan of the equine CL after the treatment with subdo…

Estrogens and progestins treatments are usually applied in equine embryo transfer programs in order to establish pregnancy in non-cyclic mares. Although standardized protocols for exogenous progestins are already described, there are no studies determining the dose and administration frequency of benzoate estradiol that, in addition to causing endometrial edema, produce similar estrogen h…
Letrozole inhibits aromatase which is responsible for estrogen synthesis. This aromatase inhibitor has been successfully used in women, cattle and rats. However, it has never been tested in cyclic mares. The effect of treatment with letrozole prior to follicle deviation (e 20mm) will be evaluated in 40 cyclic mares during a complete estrous cycle. Animals will be divided in four groups (n…
Progesterone-releasing devices associated with steroids, PGF and hCG have been successfully used to control estrus and ovulation in cows, while progestin therapies have been performed to extend the luteal phase in mares. However, intravaginal progesterone (P4) protocols for estrus synchronization in mares have resulted in unsatisfactory results at this moment. The characterization of plas…
