Evaluation of the Effect of Seminal Plasma in the Post Insemination Uterine Inflammatory Dynamic by Power Doppler Ultrasonography and Low Volume Lavage in the Mare
A modulatory role on the uterine inflammation has been suggested for equine seminal plasma (SP). The aim of this study was to evaluate the influence of SP in the uterine inflammation after artificial insemination (AI) by ultrasonography, Power Doppler ultrasonography and low volume lavage (LVL) techniques. AI was performed in twelve cycles from eight reproductive-healthy mares. Two groups were established: group A (AI with SP, n=7) and group B (AI without SP, n=5). Three stallions were used in both groups in order to avoid the individual male factor. (Source: Journal of Equine Veterinary Science)

Anti-M üllerian Hormone (AMH) Is Not a Predictive Marker of Fertility in Mares
Increasing age is inversely related to fertility in females of all species. AMH is secreted by the granulosa cells of growing follicles and plays an important role in the regulation of the early stages of follicular development [1]. In women, AMH levels progressively decline with age, reflecting a decline in ‘growing’ follicle populations, with levels eventually being undetectable in menopausal women [1]. Therefore, AMH levels are used to predict the age of onset of decreased fertility in women. (Source: Journal of Equine Veterinary Science)

Differential In Vivo Expression of Angiogenic, Proliferative, and Pro-/anti-apoptotic Factors Between Transitional Anovulatory and Early ovulatory Seasons in Mares
Little progress has been made in understanding the molecular mechanisms involved in folliculogenesis during the transition from anestrous to the ovulatory season in mares. Previous studies have used antral follicles obtained after slaughter or ovariectomy; therefore, the experimental designs were usually limited and/or compromised by the lack of follicle status monitoring. Moreover, the use of the same animals was impracticable for follow up and comparative studies. Hence, there is a need to study in vivo expression of different markers in the follicle wall to advance knowledge in antral folliculogenesis. (Source: Journal ...

Determination Whether Supplemental Application of Luteotrophic Factors (Prostaglandin E2 and Chorion Gonadotropin) Support Equine Corpus Luteum Function: In Vivo and In Vitro Studies
Mechanisms controlling development and function of equine corpus luteum (CL) may involve factors produced within and outside this gland. Progesterone (P4), a main hormone produced by CL, is necessary for pregnancy establishment and maintenance. In mares, gestation depends not only on the support of P4 but also on other luteotrophic factors such as prostaglandins (PGs). PGE2 a known luteotrophic factor, stimulates the P4 production by luteal steroidogenic cells in many species. Chorionic gonadotropin (CG) has luteinizing hormone-like activity, playing important roles in regulation of CL and endometrial functions. (Source: J...

Preliminary Results of Synchronization of Estrus and Ovulation in Jennies
There is little information on the synchronization of ovulation in jennies. In the present experiment, the intravaginal device containing progesterone (DONE ®, Fig 1) , the PGF2a (Cloprostenol, 0.2 mg in 2 ml, ), and slow-relasing GnRH analogue (DOVA®) were designed and used for inducing ovulation synchronization of jennies. From September to November in 2017, a total of 80 jennies in body condition scores of 5-6 (Vet. Record, 1996, 138(10):229-33.) w ere included in this study. The jennies were kept in the National Black Donkey Breeding Center, China. (Source: Journal of Equine Veterinary Science)
