Benefits of Supplementary Feeding

Explore the impact of supplementary feeding on fishery health in Kafue during 2005-2007, focusing on seasonal veldt quality, nutrient functions, and potential benefits. Learn about protein, energy, and phosphorus dynamics and their effects on growth, reproduction, and overall ecosystem health. Discover the theoretical benefits, as well as tangible results on Lechwe and other species.
