in appropriate formulations, mixed, and are commonly extruded. Sometimes high-moisture fruits and vegetables, browse, or other supplements are fed along with dry extrusions for purposes of environmental enhancement, as described in Chapter 13. Foods used for environmental enhancement should not be used excessively and they should not dilute energy density, which can adversely limit dry matter consumption to below needs. Likewise, these foods should not distort the nutrient balance of a diet formulated to be nutritionally complete.
