[51] The results of the study showed that water resources were being used primarily for animal agriculture; the highest categories were animal husbandry, agriculture, slaughtering and processing of meat, fisheries, and other foods.
Animal genetic resources for food and agriculture (AnGR), also known as farm animal genetic resources or livestock biodiversity, are genetic resources (i.e., genetic material of actual or potential value) of avian and mammalian species, which are used for food and agriculture purposes. AnGR is a subset of and a specific element of agricultural ...
Animal testing, also known as animal experimentation, animal research, and in vivo testing, is the use of non-human animals, such as model organisms, in experiments that seek to control the variables that affect the behavior or biological system under study. This approach can be contrasted with field studies in which animals are observed in ...
Working domestic animals including cattle, horses, yaks, camels, and elephants have been used for work and transport from the origins of agriculture, their numbers declining with the arrival of mechanised transport and agricultural machinery. In 2004 they still provided some 80% of the power for the mainly small farms in the third world, and ...
In 1954, the Universities Federation for Animal Welfare (UFAW) decided to sponsor systematic research on the progress of humane techniques in the laboratory. [2] In October of that year, William Russell, described as a brilliant young zoologist who happened to be also a psychologist and a classical scholar, and Rex Burch, a microbiologist, were appointed to inaugurate a systematic study of ...

Animal husbandry drives climate change, ocean acidification, and biodiversity loss, and kills 60 billion animals annually. [80] It uses between 20 and 33% of the world's fresh water, [81] Livestock, and the production of feed for them, occupy about a third of the Earth's ice-free land. [82]
