The American Pregnancy Association recommends 75 to 100 grams of protein per day for pregnant women. This requirement decreases to about 71 grams of protein daily for breastfeeding women, according to the University of Illinois McKinley Health Center.
Cougars become sexually mature at about 24 months of age. However, sexually mature cougars seldom breed until they have established a home range. Cougars have a gestation period of approximately 92 days. They will generally give birth to between one and four kittens, although two or three is typical. Kittens (also called cubs) weigh just over a pound at birth. Until they are two weeks old the kittenâs eyes and ears are closed.
Some seal species give birth after 330 days, fairly similar to horses. Tapirs and rhinoceroses, moderately close relatives of equines, have even longer gestations. Tapirs have pregnancies of 440 days, while the African rhinoceros has a 480-day gestation. Large animals with much shorter gestation periods include tigers (103 days), reindeer (225 days), moose (240 days), and bison (270 days). Those with considerably longer pregnancies are camels (410 days) and giraffes (425 days).
