“…However, when performed properly, and done within the first few hours post partum , manual removal of the fetal membranes does not have negative effects on mares' future fertility (Sevinga et al . ,b; Cuervo‐Arango and Newcombe ). When only a small fragment of chorioallantois (placental tag) is retained, manual manipulations within the uterus are often helpful ( Fig ).…”

Summary Any insufficiency of the equine placenta has dramatic effects on the developing equine fetus. Placental abnormalities, such as the separation of the chorioallantois from the maternal endometrium or torsion of the umbilical cord, lead to fetal demise, premature labour or abortion. These conditions are each associated with characteristic lesions on the equine placenta, which can be found during a detailed examination. These findings can be very helpful for diagnosing problems and implementing appropriate treatments for mares and affected newborn foals. Furthermore, the retention of the entire placenta or any small fragment thereof can cause metritis, laminitis and sepsis. The prompt diagnosis and aggressive treatment of this condition is necessary to save the mare from becoming seriously ill. Therefore, a thorough evaluation of the equine placenta is a crucial element of the post partum evaluation of every brood mare.

“…If the mare is treated early (≤6 h after parturition) with oxytocin (OT) infusions or injections, manual removal and subsequent high-volume uterine lavage are recommended. This results in full recovery without complications and in high pregnancy rates already after foal heat breedings (Sevinga et al 2002).…”

Use of antimicrobials for veterinary indications related to reproduction in cattle and horses is reviewed. Antimicrobial compounds are widely used to treat and prevent infections of reproductive organs. Total amounts of antimicrobials for such purposes, estimated by weight, are low compared with major uses in food animals. The most common reproduction-related indication in cattle is mastitis. The number of intramammary products available for treatment of mastitis in the European Union is high. Metritis and endometritis also require antimicrobial treatment of cattle and specific products for intrauterine administration are available. The traditions and practices associated with the use of these products vary considerably among different countries. Parenteral antimicrobial treatment is used to treat acute clinical mastitis and puerperal metritis. Pharmacological characteristics of the antimicrobial administered parenterally are critical to achieve and maintain therapeutic concentrations in the target organs. In mares, the most common indications associated with reproduction are endometritis, retained placenta and placentitis. The number of authorized antimicrobial products for horses is limited. Horses are treated individually and off-label use of antimicrobials is very common. In veterinary indications related to reproduction, treatment practices exist that cannot be considered to be evidence-based or responsible use of antimicrobials. Not all products for local treatment have proven efficacy data. Examples of unnecessary uses are routine treatment of cows with retained placenta and use of post-breeding antibiotic treatments in mares.

“…If foetal membranes are not expelled within 3 hr from foal delivery, a clinician needs to treat a case of foetal membrane retention (FMR). The retention in heavy draft mares has high incidence reaching in some farms even 50% (Sevinga, Barkema, Stryhn, & Hesselink, ; Sevinga, Hesselink, & Barkema, ). In previous study (Rapacz et al, ), the authors reported histological differences in placenta structure between mares that suffer from FMR and those that did not.…”

Protein profile of the placenta expresses its function and maintenance. Any alterations can be reflected in qualitative and quantitative changes in this profile. The aim of the present study was the evaluation of protein profile in the placenta of mares suffering from the retention of foetal membranes (FMR) by two separation methods and the comparison with physiologically released tissues. Placentas from 14 healthy, heavy draft mares were collected immediately after the expulsion of newborn. Tissues after homogenization and staining with fluorescent dyes were subjected to electrophoretic as well as chromatographic separation. Electrophoretic gels were statistically analysed for the presence and abundance of examined proteins, while some proteins were identified in chromatographic fractions. Out of 248 spots detected in endometrium, 38 differed significantly between FMR and control animals, while in allantochorion, respective values reached 241 and 27 spots (p < .05). Among identified proteins that expressed higher abundance in endometrium of FMR mares than control animals were prostaglandin reductase, dehydrogenase/reductase SDR family, and placental growth factor. These proteins are involved in regulation of parturition. Additionally, the following proteins responsible for physiological activity of a cell—guanine methyl transferase, aspartyl/asparaginyl beta‐hydroxylase and GTP‐binding protein, were identified. These proteins expressed higher abundance in allantochorion of FMR mares than in controls. This preliminary study confirmed the disturbances in protein pattern between foetal membranes in FMR and healthy mares. Further qualitative and quantitative experiments are necessary to deepen our knowledge on the mechanisms of the retention of foetal membranes in mares.
