                 •   Insulated roofs reduce the radiation and

                   conduction of solar heat through the roof to the
                   interior of the house.                                                                                                                                           Provide Feed

                 •   Remove unneeded metal objects from around houses (i.e., machinery, vehicles, nest boxes, junk)
                   that could radiate heat into open houses.
                  The key to minimizing the effects of heat stress is anticipating periods
                  of high environmental temperatures, and implementing appropriate
                  management and nutritional measures prior to the rise in temperatures.
