Book Description
The reasons concerning losses during the first months of pregnancy has special importance in equine reproduction. Most of these losses occur early in pregnancy and around 15-20% of mares that conceive will lose the embryo before day 50. Early pregnancy loss is generally characterized by the sudden disappearance of the embryonic vesicle and is due to different reasons. Several etiologies factors involving both the mother and the embryo as, inflammatory and non-inflammatory endometrial disease, progesterone insufficiency, maternal age, lactation, site of intrauterine fixation of the embryonic vesicle, stress, plane of nutrition, season or climate, chromosome abnormalities or oocyte quality are some of the factor listed. Abortion occurs from the first month of pregnancy to full term and may be have an infectious or not origin. Causes of abortion include viral or bacterial infections, ingestion of mycotoxins, stress, gene mutations, Mare Reproductive Loss Syndrome, lack of sufficient nutrients and umbilical cord abnormalities. Some mares will show signs of impending abortion but other mares will abort without warning. Premature labor, discomfort, unusual activity or having a vulvar discharge of the mare require immediate attention. Pregnancy failure in mares represents a serious economic damages, expectations, and potential genetic improvement. Therefore is absolutely important that all losses are assessed for giving an appropriate treatment, and for preventing current and future losses.
