Mares and horses are integral components of equine studies, focusing on the reproductive and behavioral aspects of equine biology. Mares, or adult female horses, play a significant role in breeding programs and are often studied for their reproductive physiology, gestation, and maternal behaviors. Horses, as a broader category, encompass both sexes and all age groups, providing a comprehensive view of equine anatomy, physiology, and behavior. Research in this area often investigates the differences and similarities between mares and other horses in terms of hormonal cycles, reproductive health, and social interactions. This page compiles peer-reviewed studies and scholarly articles that explore the biological and behavioral characteristics of mares and horses, offering insights into their roles in equine science and management.
Mares’ milk composition as related to “foal heat” scours. A CONDITION known as “foal heat” scours often develops in young foals during the mare's first estrum, which usually commences about 9 days post-partum. Various causative factors that have been suggested, although not scientifically established, include: (1) Changes in milk composition during the heat period (Henry and Morrison, 1923; Linton, 1931; Holmes and Lindquist, 1947; Doll, 1956), (2) ingestation of genital discharge (Sohnie, 1910; Udall, 1943; Siegmond, 1961), (3) ingestation of straw, feces, grass and other foreign matter (Udall, 1943) and (4) overloading of the foal's digestive t...
Some aspects of twin-gestation in the mare. A study has been made of 44 cases of twin pregnancy in mares. The fetuses, foals, fetal membranes and blood groups of parents and foals were examined in order to determine the incidence of chorio-vascular anastomosis, blood chimaerism and freemartinism. All of the twins proved to be dizygotic and 33 of the 34 pregnancies were bicornual. Fusion of the chorion was seen in 14 of 22 placentas and macroscopic choriovascular bridges were observed in five of these, although blood chimaerism was diagnosed in 11 of 25 cases (44 per cent) examined. This would indicate a high incidence of microchoriovasc...
Equine isoerythrolysis–clinical pathological observations and transfusion of dam’s red blood cells to her foal. Clinical pathological investigations in a case of equine isoerythrolysis are reported. Plasma and milk from the dam strongly agglutinated the foal's red blood cells at fifth day post partum. Red blood cells from one liter of the mare's blood were separated from plasma and after three successive washings with saline were successfully transfused into the foal. Elevated plasma transaminase activity, hypoglycemia, hypogammaglobinemia, and renal embarrassment were observed in this foal. The changes in the various plasma constituents are discussed.
