Abstract: An artificial and/or simulated environment is used to raise a domestic or commercially raised animal to promote a positive health feedback and to minimize stress on the animal. The simulated environment is used to create the façade of a free range or cage free environment, while also minimizing the exposure to inclement weather, potential predators, and other unknown or stress-inducing situations. The results include animals that have higher resistance to diseases and have a lower stress. The artificial environment can be created by projecting or otherwise showing images and/or videos depicting simulation of environments, climate, and/or other unknown situations to normalize the animals to the same.
