Insemination is the introduction of sperm (in semen) into a female or hermaphrodite's reproductive system in order to fertilize the ovum through sexual reproduction. [1] [2] The sperm enters into the uterus of a mammal or the oviduct of an oviparous (egg-laying) animal.
Animal breeding is a branch of animal science that addresses the evaluation (using best linear unbiased prediction and other methods) of the genetic value (estimated breeding value, EBV) of livestock. Selecting for breeding animals with superior EBV in growth rate, egg, meat, milk, or wool production, or with other desirable traits has ...
Artificial insemination of farm animals is common in the developed world, especially for breeding dairy cattle (75% of all inseminations). Swine are also bred using this method (up to 85% of all inseminations). It is an economical means for a livestock breeder to improve their herds utilizing males having desirable traits.
A dominant partner can also be cattle. In that case, they are instead referred to as a bull or HuBull [ 4 ] [ 2 ] and often incorporate breeding fetish components in HuCow scenes. [ 3 ] [ 4 ] In the gay community , both milking the nipples and milking the penis of its semen are popular fantasies. [ 3 ]
The notion of "meat horse" is a French specificity: [1] this term designates a livestock animal, the horse raised for the production of meat.Rural historian Marcel Mavré analyzes it as a degradation of the draft horse, the meat horse being a direct descendant of the draft horse, which is a working animal.

Insects have very diverse mating and reproductive strategies most often resulting in the male depositing a spermatophore within the female, which she stores until she is ready for egg fertilization. After fertilization, and the formation of a zygote, and varying degrees of development, in many species the eggs are deposited outside the female ...
Cuniculture is the agricultural practice of breeding and raising domestic rabbits as livestock for their meat, fur, or wool. Cuniculture is also employed by rabbit fanciers and hobbyists in the development and betterment of rabbit breeds and the exhibition of those efforts.
Many animal species have specific mating (or breeding) periods e.g. (seasonal breeding) so that offspring are born or hatch at an optimal time. In marine species with limited mobility and external fertilisation like corals , sea urchins and clams , the timing of the common spawning is the only externally visible form of sexual behaviour.
