At the same time, mixed crop-livestock systems already produced over 90% of the global milk supply as of 2013, as well as 80% of ruminant meat, [43] yet they would bear the minority of the costs, and switching all pure livestock systems to mixed crop-livestock would decrease global agricultural costs from 3% to 0.3%, while switching half of ...
The livestock sector also includes wool, egg and dairy production, the livestock used for tillage, and fish farming. Animal agriculture is a significant contributor to greenhouse gas emissions . Cows, sheep, and other ruminants digest their food by enteric fermentation , and their burps are the main source of methane emissions from land use ...
Livestock's Long Shadow: Environmental Issues and Options is a United Nations report, released by the Food and Agriculture Organization (FAO) of the United Nations on 29 November 2006, [1] that "aims to assess the full impact of the livestock sector on environmental problems, along with potential technical and policy approaches to mitigation".

Livestock operations are responsible for about 18% of greenhouse gas emissions globally and over 7% of greenhouse gas emissions in the U.S. [24] Methane is the second most concentrated greenhouse gas contributing to global climate change, [25] with livestock contributing nearly 30% of anthropogenic methane emissions.

Intensive animal farming, industrial livestock production, and macro-farms, [1] also known as factory farming, [2] is a type of intensive agriculture, specifically an approach to animal husbandry designed to maximize production while minimizing costs. [3]
Diagram of rotational grazing, showing the use of paddocks, each providing food and water for the livestock for a chosen period. In agriculture, rotational grazing, as opposed to continuous grazing, describes many systems of pasturing, whereby livestock are moved to portions of the pasture, called paddocks, while the other portions rest.

Cryoconservation is an ex situ conservation strategy that often coexists alongside in situ conservation to protect and preserve livestock genetics. [5] Cryoconservation of livestock genetic resources is primarily done in order to preserve the genetics of populations of interest, such as indigenous breeds, also known as local or minor breeds.
Continuous grazing by sheep or cattle is a widespread extensive farming system, with low inputs and outputs.. Extensive farming most commonly means raising sheep and cattle in areas with low agricultural productivity, but includes large-scale growing of wheat, barley, cooking oils and other grain crops in areas like the Murray-Darling Basin in Australia.
