Assessment Of Seasonal Variations In Forage Quality In Saanane Island National Park, Mwanza, Tanzania, George M. Sangu, Cuthbert L. Nahonyo

Tanzania Journal of Science

Seasonal variations in proteins, vitamin A, vitamin C, carbohydrates and minerals (Ca, Fe, Na, K and P) for seven most grazed and four most browsed plant species were assessed using laboratory analysis to determine what nutrient resources were available to grazers and browsers inhabiting the Saanane Island. The results indicated great seasonal variations in proteins, vitamin A, vitamin C and carbohydrates which were statistically significant with P < 0.01, F 3.444 at DF 5. Similarly, the minerals (Ca, Fe, Na, K and P) showed greater seasonal variations with K and P being higher during wet season, while Na and Fe were higher in dry season. The levels of proteins, vitamins, fibres and minerals were well above daily dietary requirements for grazers and browsers. These results suggested that both grazers and browsers were benefiting from seasonal differences in terms of available resources at disposal as animal health is regulated by levels of proteins and vitamins available in grazing and browsing materials.  Keywords: Forage Quality, Minerals, Protein Saanane, Seasonality, Vitamin
