Milk replacers include milk and non-milk proteins, and at least a portion of the non-milk protein is provided by textured soy protein. The textured soy protein is ground and extruded such that it is substantially free of anti-nutritional factors that are detrimental to young animal health or development. The milk replacers with textured soy proteins are fed to young animals, who demonstrate equal or improved performance compared to young animals fed milk replacers with the same amount of total protein and same amount of soy protein, but the soy protein is from other than textured soy protein.
