The male parent of a horse, a stallion, is commonly known as the sire and the female parent, the mare, is called the dam. [1] Both are genetically important, as each parent genes can be existent with a 50% probability in the foal. Contrary to popular misuse, "colt" refers to a young male horse only; "filly" is a young female.
A breeding mount with built-in artificial vagina used to collect semen from horses for use in artificial insemination. Semen collection refers to the process of obtaining semen from human males or other animals with the use of various methods, for the purposes of artificial insemination, or medical study (usually in fertility clinics).
A stallion is a male horse that has not been castrated. Stallions follow the conformation and phenotype of their breed , but within that standard, the presence of hormones such as testosterone may give stallions a thicker, "cresty" neck, as well as a somewhat more muscular physique as compared to female horses, known as mares , and castrated ...
A well-designed mating increases the probability of the offspring's success, although many other factors also come into play. Many thoroughbred breeding theories are implemented from other animal breeding stock practices, such as the use of inbreeding to "fix a type". Some breeding theories are qualitative, relying on judgement.
A possible explanation for this is the deeper genital cavity of S. bilineata, which stimulates the males more than when mating with guppy females. [10] Males of some species are able to immobilize females and force copulation. In pigs and boars, males grab females and maneuver the pelvis to lift the vaginal opening and facilitate copulation.
These breeding males also have short tenure, and it is common for groups of males who do not have harems to attack a breeding male in order to gain reproductive access to his females. In some cases, polygyny can lead to aggression between males. An example of species that exhibit male-male aggression under polygynous system is Allobates femoralis.

[1] [2] Some animal sexual behaviour involves competition, sometimes fighting, between multiple males. Females often select males for mating only if they appear strong and able to protect themselves. The male that wins a fight may also have the chance to mate with a larger number of females and will therefore pass on his genes to their ...
