In the United States, virtually every existing animal welfare law specifically excludes farmed animals from their purview, such as the Animal Welfare Act. The only two federal laws dealing with farmed animals are the Humane Methods of Livestock Slaughter Act, requiring that animals be rendered unconscious before being killed; and the 28-Hour Law which requires animals to be given a rest period every 28 hours during transport. Both of these laws are exploited with numerous loopholes or are simply ignored. U.S. state laws are no better. Ultimately, all laws are designed to protect the financial interest of farmers, be they individuals or multinational industrial agriculture corporations.
