The Animal Welfare Act (AWA) was the first federal law in the U.S. regulating animals in research. The AWA applies to animal carriers, handlers, dealers, breeders, and exhibitors in addition to research laboratories, and sets minimum standards of care that must be provided for animals - including housing, handling, sanitation, food, water, veterinary care and protection from weather extremes. It covers warm-blooded species, but excludes birds, rats of the genus Rattus, and mice of the genus Mus - who together constitute approximately 95% of animals in research.
On October 15, 1970, the Endangered Species Preservation Act (P.L. 89-669) is signed into law.

In 1958, the first federal Humane Methods of Slaughter Act (P.L. 85-765) is signed into law by President Dwight D. Eisenhower on August 27.

The law covers 80 percent of the livestock slaughtered (see 1978 amendments).
The Shark Conservation Act was introduced in January 2009 by Representative Madeleine Bordallo (D-GU) in the House of Representatives and Senator John Kerry (D-MA) in the Senate in April 2009.

On September 8, 1959, the Wild Horse Annie Act (P.L. 86-234), having been approved by the US Congress unanimously, is signed into law. The Act prohibits the poisoning of wild horse and burro waterholes, as well as the use of motorized vehicles to round the horses up for sale to slaughterhouses.
