Abstract: Methods for raising commercial farm animals including birds, fish and mammals, are disclosed which improve the animals' behavioral characteristics, feeding habits and mortality rates. In one embodiment of the invention, precocial birds are exposed to the combined effects of filial imprinting, environmental enrichment and music as they are raised. In another embodiment, various types of commercial farm animals are exposed to toys.

Abstract: A method for improving feeding habits, mortality rates, and overall behavior in precocial birds as they are raised combines the effects of filial imprinting, environmental enrichment, and music. One or more filial imprinting objects are disposed in a pen in which the birds, such as young heavy strain chicks, are raised. A sound system is includes with the objects to provide soothing music, such as classical music, intermittently. To further improve the living environment, a source of heat, such as an infrared bulb, is disposed in the pen, and soft texture material is placed on the imprinting objects. Significant improvements in feeding habits, mortality rates, and overall behavior are achieved with this method.
