BACKGROUND Pregnancy rates with cooled equine semen can be unsatisfactory and show great variation. Information about first cycle pregnancy rates and pregnancy rates per cycle are often lacking from publicly available records. This retrospective cohort study was performed to evaluate the fertility of the Norwegian Coldblooded trotter. The aim of the study was to compare the breeding results aft...

Samples from the uterus have mainly been used for diagnosing infertility and endometritis by bacterial culture 4, 5 , cytology 6,5 and histology. 7 The combined use of cytology and bacteriology as an aid to the diagnosis of endometritis was initially proposed more than 20 years ago. 8 The finding of polymorph nuclear cells (PMN ́s) in a sample shows the mare is suffering from an endometrial infl...

third-degree perineal lacerations in 7 mares were repaired surgically by a one-stage method (goetz technique). primary healing occurred in all of them without any complication. the conception rate obtained after surgery was 70.1%. five horses out of seven got pregnant after surgery and no further injury was seen at subsequent foaling. three mares have produced several healthy foals without any ...

Pregnant Anglo-Arab and Thoroughbred mares (n = 24) were divided randomly according to age and breed into 4 groups of 6 mares each from approximately 6 weeks before their expected foaling date. Diets received by the 4 groups varied in essential amino-acid and total protein contents. Serum progestagen, FSH and LH concentrations were determined from the day of parturition until foal heat and duri...

Intra-partum conditions in the mare include premature separation of the allanto-chorion, failure to lie down or strain uterine inertia and dystocia. Dystocia in the mare is a rare event but a true emergency when it occurs. Because of the long extremities and the strong contractions that occur during parturition malposture of a long fetal extremity or head deviation is the commonest cause of dys...

Hydrops conditions of the placenta in the mare are uncommon, with hydrops allantois being reported more frequently than hydrops amnion. The condition in the mare usually develops during the last trimester of pregnancy and is characterized by the excessive accumulation of allantoic (hydrops allantois) or amnionic fluid (hydrops amnion). The sequelae of unnoticed or untreated hydrops allantois/ a...
