A marsupial has a short gestation period, typically shorter than placental. For more information on how these estimates were ascertained, see Wikipedia's articles on gestational age. The gestation figures given here are shown in days. They represent average values and should only be considered as approximations.

[citation needed] Mating occurs throughout the year with a gestation period of approximately 277–290 days. Most commonly a single calf is born, but twins are not unknown. Sexual maturity is reached at about eighteen months. Highland cattle also have a longer expected lifespan than most other breeds of cattle, up to 20 years. [24]

The cows teat is a projection of the mammary gland that is sealed during their dry period. A dry cow refers to a dairy cow that is in a stage of their lactation cycle where milk production ceases prior to calving. This part of their lactation cycle is referred to as the cows dry period and typically last between 40 and 65 days. [1]
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 ...
