A typical precocial mammal has a gestation period almost four times longer than a typical altricial mammal of the same body size. [20] Precocial mammal species generally have greater adult body weights than altricial mammals as precocial mammals have markedly longer gestation periods than altricial mammals. [21]
The female signals her readiness for copulation by straddling her legs and raising her tail. The gestation period lasts around a year, and a single young is produced. Mares may give birth to one foal every twelve months. The birthing peak is during the rainy season. A mare gives birth within the vicinity of her group and while lying down on her ...
The gestation period is 330–500 days, being longest in rhinos. Newborn perissodactyls are precocial, ... Equus zebra. Cape mountain zebra, Equus zebra zebra;
Female zebras can have one foal per year. Their gestation period is around 360–395 days long, depending on the species. The mother will protect her foal, and it can stand, walk, and run shortly after birth. This is especially important, as foals are vulnerable to predators. Foals will nurse from their mother for up to one year before being ...
Gestation of the Grévy's zebra normally lasts 390 days, [17] with a single foal being born. A newborn zebra will follow anything that moves, so new mothers prevent other mares from approaching their foals while imprinting their own striping pattern, scent and vocalisation on them. [17] Mares with young foals may gather into small groups. [21]
The duration of this period varies between species. For most species, the amount a fetus grows before birth determines the length of the gestation period. 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 ...
[21] [7] The gestation period for Chapman's zebras is around 12 months, after which time the female will give birth to a single foal. [26] The foal is soon able to walk with the rest of the group. This is essential for its survival, as it ensures that the mother does not have to leave it behind for the good of the other members of the harem. [12]
The gestation period is anywhere from 221 to 229 days and the female is receptive to mating about 10 days after parturition. [15] The mother will only birth one calf at a time. A newborn can weigh from 1270 to 1550 g at birth. During the first ten days after birth, referred to as the lactation period, a newborn grows at a rate of about 94 g/day ...
