Animal husbandry in the British Agricultural Revolution of the 18th century, when livestock breeds like the Dishley Longhorn cattle and Lincoln Longwool sheep were rapidly improved by agriculturalists such as Robert Bakewell to yield more meat, milk, and wool. A wide range of other species such as horse, water buffalo, llama, rabbit and guinea pig are used as livestock in some parts of the world. Insect farming, as well as aquaculture of fish, molluscs, and crustaceans, is widespread. Modern animal husbandry relies on production systems adapted to the type of land available. Subsistence farming is being superseded by intensive animal farming in
Animal genetic resources for food and agriculture knowledge, as internationally agreed."" Which is monitored by the following indicators: "2.5.1: Number of plant and animal genetic resources for food and agriculture secured in either medium or long term conservation facilities. 2.5.2: Proportion of local breeds, classified as being at risk, not at risk or unknown level of risk of extinction." Although policies can have some negative consequences, they are nonetheless important. Lack of adequate policies can lead to the insufficient capacity to manage AnGRs, further a loss of genetic diversity and marginalization of relevant stakeholders, such as pastoralists, who are valuable players in maintaining livestock diversity.
