===Reproduction===
Mating occurs in late spring or early summer. Mating stallions do not start looking for mating partners until the age of five. Stallions assemble groups of mares or challenge the leader of another group for dominance. Females are able to give birth at the age of three and have a gestation period of 11–12&nbsp;months. Foals are able to stand about an hour after birth.<ref name=ADW>{{cite web |last=Luu |first=J. |title=''Equus caballus przewalskii'' |url=http://animaldiversity.org/accounts/Equus_caballus_przewalskii/ |publisher=University of Michigan Museum of Zoology |website=Animal Diversity Web |access-date=29 April 2019 |archive-date=20 April 2019 |archive-url=https://web.archive.org/web/20190420173012/https://animaldiversity.org/accounts/Equus_caballus_przewalskii/ |url-status=live }}</ref> The rate of infant mortality among foals is 25%, with 83.3% of these deaths resulting from leading stallion [[Infanticide (zoology)|infanticide]].<ref name=Xinjiang/> Foals begin grazing within a few weeks but are not weaned for 8–13 months after birth.<ref name=ADW/> They reach sexual maturity at two years of age.<ref>{{cite web |title=Przewalski's Horse |url=https://www.aboutanimals.com/mammal/przewalskis-horse/ |website=aboutanimals |date=4 February 2016 |access-date=29 April 2019 |archive-date=20 April 2019 |archive-url=https://web.archive.org/web/20190420172947/https://www.aboutanimals.com/mammal/przewalskis-horse/ |url-status=live }}</ref>
