Percent and count of total regulated animals used in 2014 for: A) animals used for teaching, testing, experimental, or research projects (left column), and; B) animals held for breeding, conditioning, or future use during the reporting period (right column). Data in each column is demarcated by USDA defined categories of regulated species used in research (excludes aquatic species, birds, rats, and mice). Data from the Annual Report of Animal Usage by Research Facilities, Fiscal Year 2013 [Animal Plant and Health Inspection Service 2014]. Figure footnote: It is important to note that the vast majority of animals used in research are “non-regulated” (e.g., rodents). Thus the percentage of nonhuman primates used in research is actually very small percentage of total number of animals used in research.
