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."
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 ...
In these specific instances, the breeder strives to meet standards in each animal set out by organizations. A breeder may also assist with breeding animals in the zoo. In other cases, a breeder can be referred to an animal scientist who has the capabilities of developing more efficient ways to produce the meat and other animal products humans ...
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 ...
Example of a pedigree chart using Ahnentafel numbering A pedigree chart is a diagram that shows the occurrence of certain traits through different generations of a family, [ 1 ] [ 2 ] most commonly for humans , show dogs , and race horses .
Modern animal husbandry relies on production systems adapted to the type of land available. Subsistence farming is being superseded by intensive animal farming in the more developed parts of the world, where, for example, beef cattle are kept in high-density feedlots, and thousands of chickens may be raised in broiler houses or batteries. On ...
It is used in the breeding of both plants and animals, but is most commercially important in animal breeding to determine the true breeding value of an animal (especially males) which are used extensively for propagation of best germplasm. The extensive use of artificial insemination in domestic animals has helped in increasing the selection ...
The diversity of animal genetic resources includes diversity at species, breed and within-breed level. Known are currently 8,800 different breeds of birds and mammals within 38 species used for food and agriculture. [1] The main animal species used for food and agriculture production are cattle, sheep, goats, chickens and pigs. In the livestock ...
