The following breeds have a short gestation period (note that not all breeds with short gestation periods will be listed here):
It was originally believed that rate of maturity was correlated with rate of gestation. This is now not the case. Rate of maturity is simply carcass maturity, or the time when an animal starts to lay down fat, and has nothing to do with age of puberty nor gestation length.
Limousin are selected to have long gestation periods, which is around 290 to 300 days (or more) in length.
Small ones.
Angus cattle tend to have short gestation periods, ranging from 260 to 280 days in length. However, this can be the exception rather than the rule. Because Angus are so popular and wide-spread, it shouldn't come to a surprise that some strains may have average or slightly long gestation periods ranging from 280 to 290 days long.
Thier gestation periods are diffrent. Marsupials have a short gestation date while mammels are normally long.
Smaller mammals have shorter gestation periods. If a mother mouse kept her young inside her uterus/placenta for too long, the young would become so big that the mother would die. Also, mice have very short lifespans due to their heavy predation and small size, so a female mouse needs to produce as many young as possible in her short life in order to keep the species from going extinct. A short gestation period increases fertility in that more litters can be produced in the same amout of time. Thus, mice have evolved very short gestation periods. Although a mouse's gestation period is only about 20 days, there are some mammals, such as certain opossums, whose gestation periods are even shorter.
No. Placental mammals tend to have longer gestation periods than marsupials, depending on the size of the animal.
The gestation periods for mammals differs greatly. In general it appears to be very short in small mammals, (some shrews and mice are only a few days) while increasing in length as the mammal increases in size. Elephants, hippos, bears whales and other large mammals have gestation periods lasting 9 to 18 months.
On hills, in the trees, in barns or sheds, in the grass or dirt, etc. Most cattle love to sleep on hills because they can easily see predators approaching from below.
Bos taurus, also known as European cattle, are distinguished from other cattle breeds by their large size, muscular build, and docile temperament. They typically have a straight back, short horns, and a variety of coat colors. Bos taurus are known for their high milk production and are commonly used for beef production.
The eastern short horned lizard has a gestation period of 3 months.
Gestation period and lifespan are positively correlated, as the Animals with fast life cycles (short lifespan) will have fast gestation periods. This is because they evolved to live quickly due to predators and competition for food. Professor William Amos, Professor of Evolutionary Genetics, University of Cambridge
Marsupials in general have short gestation periods since the babies are born into the pouch at a rather underdeveloped state. I think the shortest animal gestation period if I remember correctly is that of the opposum, it's 12-13 days long.
