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 ...
Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together.
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."
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 eat. [1] Earnings as a breeder vary widely because of the various types of work involved in the job title.
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 ...
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.
Molecular breeding is the application of molecular biology tools, often in plant breeding [1] [2] and animal breeding. [3] [4] In the broad sense, molecular breeding can be defined as the use of genetic manipulation performed at the level of DNA to improve traits of interest in plants and animals, and it may also include genetic engineering or gene manipulation, molecular marker-assisted ...
Some experiments require the keeping of several generations of animals treated with a particular drug, in order to fully appreciate the side effects of that drug. There is also the matter of breeding and raising animals for experiments. The New Zealand White is one of the most commonly used breeds for research and testing.
