Abstract
Chemical constituents, organic matter (OM) digestibility, gross and metabolizable energy, rumen degradable and undegradable N, amino acid composition, digestion kinetics (leaves, their neutral-detergent fibre and cell solubles), and antinutritional factors were determined in extracted (EL) and unextracted (UL) Moringa oleifera leaves. The metabolizable energy and OM digestibility predicted from the extent of fermentation in in vitro incubation were 9.2 MJ/kg and 75.7% for the EL and 9.5 MJ/kg and 74.1% for the UL. The crude protein (CP) contents of the EL and UL were 43.5 and 25.1%, respectively. The true protein contents of these leaves were 93.8% and 81.3% of the total CP (non-protein N contents of 2.7 and 4.7% were observed in the EL and UL). In vitro rumen CP degradability at 24 h of incubation was 44.8 and 48.6% for the EL and UL. Moringa oleifera leaves had negligible tannins; saponins content was similar to that present in soybean meal, and trypsin inhibitors and lectins were not detected. The phytate content was 3.1%. The ethanol extracted leaves were virtually free of tannins, lectins, trypsin inhibitors and saponins, and phytate content was 2.5%. All essential amino acids including S-containing amino acids were higher than the adequate concentration when compared with the recommended amino acid pattern of FAO/WHO/UNO reference protein for a 2- to 5-year-old child.
