Title: Nutritive Evaluation Of Two Flood Grasses In White Nile – Sudan
Author: Mahala, A.G.; Elnadeef, Y.M.A
Abstract: Flood grasses (Echinochloa stagnina and Echinochloa pyramidalis) were evaluated as animal feed in term of chemical composition and in vitro digestibility. Crude protein (CP) content was significantly (P < 0.05) higher in Echinochloa stagnina (9.7%) than in Echinochloa pyramidalis (6.5%). Acid-detergent fibre (ADF) (51.6%), Nitrogen-free extractive (NFE) (31.4), Neutral-detergent fibre (NDF) (69.8) and Ether extract (EE) (0.69) in Echinochloa stagnina were lower than in Echinochloa pyramidalis (55.7%, 35%, 73%, 0.95%) for ADF, NFE, NDF and EE respectively. Sodium (Na) content (0.7%) was significantly (P > 0.05) higher in Echinochloa pyramidalis than in Echinochloa stagnina (0.3%) and Calcium (Ca), Phosphorus (P), Potassium (K) and Magnesium (Mg) were (0.30% and 0.40), (0.60% and 0.60%), (1.60% and 1.70%) and (0.20% and 0.40%) in Echinochloa stagnina and Echinochloa pyramidalis respectively. In vitro dry matter digestibility (IVDMD) of Echinochloa stagnina (63%) was significantly (P > 0.05) higher than in Echinochloa pyramidalis (56%) as well as the values of Digestible acid-detergent fibre (DADF) (69.8%: 54%), Digestible neutral-detergent fibre (DNDF) (71%: 58.5%), and Digestible crude fibre (DCF) (38.3%: 33%). From obtained results it can be concluded that the two species of Echinochloa contribute most of livestock nutrients requirement. Further research required to improve their nutritional value, digestibility and feed intake
