Hence, seasonal breeders can be divided into groups based on fertility period. "Long day" breeders cycle when days get longer (spring) and are in anestrus in fall and winter. Some animals that are long day breeders include ring-tailed lemurs, horses, hamsters, groundhogs, and mink. "Short day" breeders cycle when the length of daylight shortens ...
In the horse breeding industry, the term "half-brother" or "half-sister" only describes horses which have the same dam, but different sires. [6] Horses with the same sire but different dams are simply said to be "by the same sire", and no sibling relationship is implied.

Some animals are capable of asexual reproduction, which often results in a genetic clone of the parent. This may take place through fragmentation; budding, such as in Hydra and other cnidarians; or parthenogenesis, where fertile eggs are produced without mating, such as in aphids. [40] [41]
In this clip, a pair of horses are determined to go swimming in a local pond, no matter how little water they might find there. In this video, two beautiful chestnut horses are enjoying playing in a.
Sexual behavior can be classified into behavioral states associated with reward motivation ("wanting"), reward consummation also known as pleasure ("liking"), and satiety ("inhibition"); [12] these behavioral states are regulated in mammals by reward-based sexual learning, fluctuations in various neurochemicals (i.e., dopamine − sexual desire ...
