Przewalski's horse  (Equus ferus przewalskii)

Przewalski's horse feeds on grasses and other plants, while in captivity it also takes hay and grain (4). Most of the day is spent foraging, as it feeds on food with a low nutritional content. In the wild, Przewalski's horse occurs in family groups led by a dominant stallion, juveniles were ousted and the males formed their own bachelor groups before attempting to take over a band of females (6). In captivity, births occur in April/May but in the wild the season is later and more likely to be May/June (5). Gestation takes between eleven and twelve months and foals are able to stand as soon as one hour after birth (4). A week after giving birth, females come into heat and will mate again (5).
