  1. The 1973 and early 1974 annual report did not request the number of animals used in research, but only requested the number of experiments involving unrelieved pain or distress for animals. This is the first year reports were required. From late 1974 to 1978, only animals involving unrelieved pain or distress were required to be reported. The number of experiments reported in 1973 and 1974 are shown in parentheses, with the numbers of animals reported shown each year thereafter.

  2. In late 1974, a revised reporting form was distributed to research facilities requesting the number of animals exposed to unrelieved pain rather than the number of experiments. Figures for both the number of animals and the number of experiments are shown for 1974.

  3. Reports on the number of animals used subject to unrelieved pain (no drugs) were reported only from January 1, 1977, through September 30, 1977, because of a change in reporting from calendar year to fiscal year.

  4. The 1979 annual report was the first report to list both the number of animals used involving pain that was relieved by drugs and the number of animals used involving unrelieved pain (no drugs).

  5. APHIS reorganized the animal welfare program effective October 1, 1988. Animal welfare was moved from Veterinary Services to Regulatory Enforcement and Animal Care. This transition affected reporting lines and procedures and could have affected the data in both reporting categories.

  6. The reporting of animals used involving no pain and no drugs, in addition to the two previous categories, was required in the 1989 annual report.
