Przewalski's horse feeds on grasses and other plants, while in captivity it also takes hay and grain (3). Most of the day is spent foraging, as it feeds on food with a low nutritional content. In the wild, Przewalski's horse occurred 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 (5). In captivity, births occur in April/May but in the wild the season is later and more likely to be May/June (6). Gestation takes between eleven and twelve months and foals are able to stand as soon as one hour after birth (3). A week after giving birth, females come into heat and will mate again (6).
