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 ...
Capital breeding and income breeding refer to the methods by which some organisms perform time breeding [1] and use resources to finance their breeding. [2] The former "describes the situation in which reproduction is financed using stored capital; [whereas the latter] [...] refers to the use of concurrent intake to pay for a reproductive attempt."
The mammalian female reproductive system contains three main divisions: the vagina and uterus, which act as the receptacle for the sperm, the ovaries, which produce the female's ova, and the vulva, which consists of the labia and clitoris. The vagina, uterus and ovaries are always internal while the vulva is external.
If the breeding is for a purebred animal that will be used for exhibition or future breeding (pets or livestock), the animal must be registered and conform to the criteria laid out for that breed in a breed standard kept by a central authority, such as a kennel club for dogs. In addition, the breed club, kennel club, or other governing ...
The final leg of rabbit breeding—beyond meat, wool, fur, and laboratory use—was the breeding of 'fancy' animals as pets and curiosities. The term 'fancy' was originally applied to long-eared 'lop' rabbits, as they were the first type to be bred for exhibition. Cuniculture in Germany in 1916
An alternative definition of the term bioculture is all the practical aspects of the use of living things in culture, including agriculture, production of food and clothing, forestry, animal breeding and training, the pet trade, use of living things in science, zoos and aquariums, animal sports, and the raising of game for sport hunting.

One example of this change in breeding goals is the pronounced sloped back in the modern German Shepherd breed, compared to the straight back of working pedigrees. The Shar Pei is an example of how differing breed standards can influence the direction breeders take a dog and which traits are exaggerated.
The reproductive system of an organism, also known as the genital system, is the biological system made up of all the anatomical organs involved in sexual reproduction. Many non-living substances such as fluids, hormones , and pheromones are also important accessories to the reproductive system. [ 1 ]
