Which law was enacted to prevent cruelty to animals used for transportation?

The 28 Hour Law was enacted to prevent cruelty to animals during commercial transport by ensuring that animals are not confined and transported for longer than 28 consecutive hours without being unloaded for food, water, and rest. This law recognizes the stress and suffering that can occur when animals are transported over long distances and establishes a maximum timeframe for transportation to safeguard their welfare.

The other laws mentioned focus on different aspects of animal treatment. The Animal Welfare Act establishes broader standards for the treatment of animals in various settings, including research and exhibition. The Horse Protection Act specifically targets the prevention of inhumane practices, such as soring, in horses. The Humane Slaughter Act mandates humane treatment during the slaughtering process but does not address transportation directly. Each of these laws plays a role in protecting animal welfare but serves different specific purposes within that context.
