Mares carry their young (called foals) for approximately 11 months from conception to birth. (Average range 320–370 days.) [2] Usually just one young is born; twins are rare. When a domesticated mare foals, she nurses the foal for at least four to six months before it is weaned, though mares in the wild may allow a foal to nurse for up to a year.
However, after the birth it is important that these neurosteroids stop. Horses are prey animals, with a strong flight response. If these neurosteroids continue to suppress the movement and reactions of a foal, it would be at a greater risk in the wild. Foals should be up and ready to run around shortly after birth, typically within a few hours.
A stallion mating with a mare. While horses in the wild mate and foal in mid to late spring, in the case of horses domestically bred for competitive purposes, especially horse racing, it is desirable that they be born as close to January 1 in the northern hemisphere or August 1 in the southern hemisphere as possible, [11] so as to be at an ...
A foal will nurse for at least four months before being weaned when under human management, and have been known to nurse for up to a year in the wild. It is typical for foals under human management to be weaned between four and six months of age, though under natural conditions, they may nurse for longer, occasionally until the following year ...
The species prefers a warm and moist environment and is most likely to infest horses and monkeys, [1] and particularly the proximal small intestines of foals. [2] Their eggs can be found in the feces of fouls which are younger than two months ; larvae can be isolated in the milk of the mare from day five to day 45 postpartum; [3] also can occur in liver, lungs and mammary tissue; Parasitic ...

Altricial birds are less able to contribute nutrients in the pre-natal stage; their eggs are smaller and their young are still in need of much attention and protection from predators. This may be related to r/K selection; however, this association fails in some cases. [18] In birds, altricial young usually grow faster than precocial young.
Bigger eggs mean bigger young that have a higher survivability rate. [18] In a study of zebra finches, it was determined that those which were fed a lower quality diet laid eggs that were lighter and less nutrient-rich than those zebra finches which were fed a higher quality diet.
