Abstract

Twinning in mares is undesirable since it very often leads to abortion, stillbirth or delivery of weak foals. Some mares produce two follicles and release two ova during a cycle, and if both are fertilized, a twin pregnancy results. The early ultrasound diagnostic of the pregnancy is very...

Abstract

The occurrence of twin pregnancies in mares is an undesirable event. Fortunately, the equid has evolved to naturally self-reduce one of the pregnancies if they are positioned unilaterally. There are reports of increased rates of monozygotic twinning when assisted reproductive technologies (ART) are ...

Abstract

Because of the growing importance of horses in leisure and several sports, somatic cell nuclear transfer (SCNT) is being used more frequently for cloning animals for performance and reproductive purposes. However, because of the need to perforate the zona pellucida during microsurgical...

Abstract

Objective: Transvaginal ultrasound-guided aspiration (TUA) is a procedure which can be used for the reduction of twins post-fixation in the mare. The aim of this study was to evaluate the effect of the age of mares and the day of gestation on the outcome of TUA treatment. Material and methods: In...

Abstract

In horses, twin pregnancy is pathological and represents a potentially life-threatening condition to the mare and foal. Twinning occurs in approximately 2% of pregnancies. Of these, the majority of cases are dizygotic twins, resulting from 2 ovulations and monozygotic twins are rare. A 12-year-old...

Abstract

Horses have low fertility, which affects profitability of breeding. Additional economic loss is generated by various complications accompanying twin pregnancies which are particularly prevalent in Thoroughbred horses. Therefore it is important to identify environmental and genetic factors...

Abstract

Equine twins that survive gestation and the first few days postparturition are relatively rare, and growth data for equine twins are missing from the published literature. Documentation of the growth and developmental patterns of equine twins should be helpful in establishing expected rates of...

Abstract

The presence of twinning has long been recognized as one of the most important causes of reproductive wastage in the mare. The incidence of abortion due to twinning has declined subsequent to the routine use of ultrasonography for pregnancy diagnosis. The early and accurate diagnosis and management ...

Abstract

We evaluated an intravaginal adhesive muco-nano liposomes tablet with low dose 5 mg progesterone (P4) and 50IU pregnant mare serum gonadotropin PMSG (MAG) on onset and duration of estrus, ovulation, pregnancy, lambing, litter, twins and serum P4 in groups on 10 ewes each. The formulations were...

Abstract

While the use of ultrasonography has reduced twin pregnancies as a major cause of abortion in the mare, diagnosis of twins past the mobility stage still occurs and requires special management techniques. After cessation of the mobility phase, and prior to day 60, options for twin management include ...
