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.
In alpacas, pregnancies last 11 to 12 months, and usually result in a single cria. Twins are rare, approximately 1 ⁄ 1000, slightly rarer than the proportion of twins in human births. Twin cria births are not only rare, but dangerous.
Alpacas were domesticated thousands of years ago. The Moche people of Northern Peru often used alpaca images in their art. [6] Traditionally, alpaca were bred and raised in herds, grazing on the level meadows and escarpments of the Andes, from Ecuador and Peru to Western Bolivia and Northern Chile, typically at an altitude of 3,500 to 5,000 metres (11,000 to 16,000 feet) above sea level.

At 8–12 weeks of gestation, liver is a relatively bigger organ which forms 4-5-5.5% of the total body weight and protrudes through the abdominal wall. By 13 to 32 weeks of gestation, it forms 3.4% to 4.0% of the total body weight. [23] The liver weight hence forms a more or less constant proportion of the total body weight of the fetus. [24]
The Huacaya alpaca is a breed of alpaca (Vicugna pacos) that has a unique appearance and fiber quality. [1] This breed is the most popular alpaca breed with population numbers reaching 2.8 million in Peru alone. [2] They share biological components with other species in the Camelidae family. Their digestive tract, nutrition requirements, and ...
