the objective of this study was to review the literature on sperm transport in the mare. during this process the sperm cells must reach the oviducts in order to fertilize the oocyte, but before reaching this site it must go through the uterus that is a hostile environment at this moment since there is an inflammatory reaction in this location that aims to eliminate excess spermatozoa and bacter...

Introduction an optimal broodmare feeding program will consider the maintenance of the mare, the growth and development of the fetal foal, and the production of milk. The impact of a broodmare feeding program can be substantial on not only the health of the mare, but also the development of the foal and the future equine athlete. The nutritional requirements of the broodmare vary depending on h...

Lunar volcanic deposits are dominated by areally extensive mare units occurring in regionally low areas predominantly on the lunar near side. Data obtained from lunar orbit and earth-based observations have been used to extend the detailed characterizations derived from Apollo and Luna sample return missions to other parts of the moon. Mare volcanism occurred over a period of about 1.3 billion ...

Adoption of nongenetic offspring occurs in a variety of species but is rare in equids. We report a case of adoption by a free-ranging, feral mare Equus caballus and compare the maternal care received by her genetic offspring (born 1995) to that of her adopted offspring (born 1996) for the first 30 weeks of development. We compare five measures of care: (1) total time spent suckling, (2) mare ag...

High spatial resolution Clementine images are examined to measure the reflectance properties of small and optically immature mare craters that have sampled discrete compositional units. The spectral properties of these relatively crystalline mare materials are compared to associated mature soils to determine the effects of space weathering on specific basalt types. Space weathering is observed ...

Cryptomaria, lunar volcanic deposits obscured by crater and basin impact ejecta, can provide important information about the thermal and volcanic history of the Moon. The timing of cryptomare deposition has implications for the duration and flux of mare basalt volcanism. In addition, knowing the distribution of cryptomaria can provide information about mantle convection and lunar magma ocean so...

History: Placental tissues submitted were from a 12-year-old, multiparous, Quarterhorse mare. The mare produced a live foal in 2006. The mare was pregnant in 2007 with a thickened placenta detected by ultrasound at 290 days of gestation. The animal was treated medically for placentitis and delivered a live foal naturally at 310 days of gestation. The placenta was submitted for laboratory analysis.

Introduction: The A16 (Apollo16) site in the lunar nearside highlands is 220 km from the nearest mare. Thus it is no surprise that mare basalt samples are uncommon at the site. Here, we present the petrography and geochemistry of 5 new mare basalt samples found at the A16 site. We also discuss possible provenances of all A16 mare basalt samples using high-resolution global data for the distribu...

A deflation technique is presented for an irreducible singular M -matrix Algebraic Riccati Equation (MARE). The technique improves the rate of convergence of a doubling algorithm, especially for an MARE in the critical case for which without deflation the doubling algorithm converges linearly and with deflation it converges quadratically. The deflation also improves the conditioning of the MARE...

Uterine torsion in the mare is an uncommon but life-threatening event for both the pregnant mare and the fetus. Most cases occur in the last 60 days of gestation but before the onset of labor. Uterine torsions are often diagnosed as an acute event with the affected mare showing mild to moderate signs of colic, although violent colic episodes do not preclude the diagnosis of uterine torsion. Col...
