Objective: This prospective study aims to compare three different sampling techniques for the collection of endometrial cytological specimens in the mare: the guarded culture swab, the uterine cytobrush and the low volume uterine flush. Material and methods: The study po pulation consisted of six healthy Standardbred mares in dioestrus. In each mare an acute endometritis was induced by performi...

induced abortion may be desired during a normal or abnormal pregnancy. the methods of induced abortion differ between species mainly because of different sources for progesterone production during pregnancy between species and within a species according to different stages of gestation. in cows and buffaloes, pregnancy can be effectively terminated from 5 to 150 days by administration of luteol...

anti-müllerian hormone (amh) has been observed to decrease with the development of hemorrhagic anovulatory follicles (hafs) in mares. two studies were conducted to evaluate amh concentration in mares with hafs compared to seasonally anoestrous and cyclic mares, and to elucidate changes of amh with the development of luteinised unruptured follicles (lufs). in study 1, amh and progesterone were e...

Mare domes, small shield volcanoes typically <∼30 km diameter, are part of the spectrum lunar volcanic features that characterize extrusive basalt deposits. We used new spacecraft data to document these in Tranquillitatis, among oldest maria and site commonly interpreted as an ancient degraded non-mascon impact basin. found 283 known suspected mare with majority (n = 229) concentrated on a broa...

[1] Basaltic volcanism is widespread on the lunar nearside, and returned samples suggest that the mare-forming magmas had low viscosity that led to primarily sheet-like deposits. New 70-cm wavelength radar observations that probe several meters beneath the lunar surface reveal differences in mare backscatter properties not explained by age or compositional variations. We interpret areas of high...

In experiment 1, 6 pregnant mares received a concentrate that contained a trace mineral premix that provided 14.3 mg Cu, 40 mg Zn, 28 mg Fe, 28 mg Mn, 0.08 mg Co, 0.16 mg I, and 0.16 mg Se/kg concentrate (group A). Seven mares received the same concentrate plus 502 mg Zn and 127 mg Cu once daily (group B). No differences (P .05) in foal growth data, or Cu, Zn, and Fe concentrations of mare milk...

Hedberg Alm, Y. 2006. Oestrus in the mare with emphasis on deviant behaviour and adrenal gland function. Some owners appear to experience problems with their mares due to excessive oestrous signs and/or changes in their mare's behavioural characteristics across the oestrous cycle. Few such mares are examined at equine clinics and, thus, the cause of such behaviour is often unknown. Adrenal sex ...

All current approaches to manipulating the reproductive biology of the nonpregnant mare are discussed.
