This is a collection of lists of mammal gestation period estimated by experts in their fields. The mammals included are only viviparous (marsupials and placentals) as some mammals, which are monotremes (including platypuses and echidnas) lay their eggs. A marsupial has a short gestation period, typically shorter than placental.
The minimum cost of breeding for a mare owner includes the stud fee, and the cost of proper nutrition, management and veterinary care of the mare throughout gestation, parturition, and care of both mare and foal up to the time of weaning. Veterinary expenses may be higher if specialized reproductive technologies are used or health complications ...
Smaller species normally have a shorter gestation period than larger animals. [2] For example, a cat's gestation normally takes 58–65 days while an elephant's takes nearly 2 years (21 months). [3] However, growth does not necessarily determine the length of gestation for all species, especially for those with a breeding season. Species that ...
Equine chorionic gonadotropin (acronym given as eCG but not to be confused with ECG) is a gonadotropic hormone produced in the chorion of pregnant mares. Previously referred to as pregnant mare's serum gonadotropin ( PMSG ), the hormone is commonly used in concert with progestogen to induce ovulation in livestock prior to artificial insemination .
A newborn foal A foal will be able to run alongside of its dam within a few hours of birth.. Foals are born after a gestation period of approximately 11 months. [1] Birth takes place quickly, consistent with the status of a horse as a prey animal, and more often at night than during the day.
Gestation is the period of development during the carrying of an embryo, and later fetus, inside viviparous animals (the embryo develops within the parent). [1] It is typical for mammals, but also occurs for some non-mammals. Mammals during pregnancy can have one or more gestations at the same time, for example in a multiple birth. [2]

Mare with a foal. Gestation lasts approximately 340 days, with an average range 320–370 days, [50] [51] and usually results in one foal; twins are rare. [52] Horses are a precocial species, and foals are capable of standing and running within a short time following birth. [53] Foals are usually born in the spring.
