Supporters emphasize humane treatment of animals
Believe that animals can be used to benefit humans
Some take the position that there are essential (food, medical research) and non-essential (entertainment) uses
Livestock producers support proper feeding, housing, vet care and good management practices because these result in greater productivity.
Views vary. Some advocate the total elimination of all animal
use by humans. Others focus on eliminating animal suffering to
the greatest extent possible. Those who take a moderate approach try to
achieve their goals by influencing legislation and through public education campaigns.
Laws are enforced by The Animal and Plant Health Inspection Service (APHIS) of the USDA
First federal law dealing with the humane treatment of animals was passed in 1873.
Other legislation can be found on page 23 of the text.
Currently a variety of methods. The USDA is developing a database of
information about individual animals. They would like to make this system mandatory To learn more about NAIS please visit
