Evaluation of the reproductive and metabolic problems during the breeding seasons in arabian barren mares

The aim of the present study was to investigate the reproductive and metabolic problems, treat with appropriate and current treatment approaches and evaluate the treatment success in Arabian barren mares during the two breeding seasons.Twenty seven barren mares, ranged from 4 and 21 years of age, were used as material. The mares used in this study were not concieve in previous season or pregnancy was not occured during the breeding season although insemination was made three times. The condition of uterine and ovarian was evaluated by the ultrasonographical and gynecological exam procedures. Endometrial swabs, smears, biopsy and blood serum samples were taken for microbiological, cytological, histopathological exam and diagnosis of metabolic diseases, respectively. Endometrial biopsy samples were scored histologically according to Kenney and Doig scale. The appropriate and current treatment approaches to barren mares which were detected pathological conditions were applied.The mean age of subfertile and fertile mares in first breeding season were 12,9 and 12,0 while the mean age of subfertile and fertile mares in second breeding season were 15,4 and 12,8, respectively. The percentage of microbial growth in the first and second breeding season were detected as 70.6 % and 37.5 %, respectively. The most frequently isolated species in subfertile mares were Klebsiella pneumoniae. The percentage of cystic uterine structures in the first and second breeding seasons were 23.5% and 16.7%, respectively. Although uterine fluid accumulation was observed in 5 mares out of 17 in first breeding season, it was not detected in second breeding season in mares. As a result, 5 out of 27 mares were not conceived in two breeding seasons. 2 out of 5 mares had the equine metabolic sendrome.As a result; it is obvious that; contagious agents originated from the stallion may have an important role on the fertility in mares, while the most important reason for subfertile mares is derived from the uterine drainage problems, cystic uterine structures, vulvar deformity and metabolic disease.
