ZuPreem relaunches Natural Premium Daily Bird Food in four sizes. The new formulation features multigrains such as ground millet, oat groats, wheat, barley and corn. The new diet also includes vegetables and fruit while maintaining the color and shape of the original formula, the company reports. Bird owners may recommend the food as the best pelleted diet to convert a bird from seed to nuggets, the company states. Redesigned bags are made to accommodate various shelf spaces, and the ZuPreem brand has been made more visible, the company adds.
