Title: Chemical Composition and in Vitro Gas Production Characteristics of Six Fodder Trees Leaves and Seeds
Author: Mahala, Ahmed Gofoon; Fadel Elseed, Abdel Nasir M.A
Abstract: The aim of this study is to evaluate six fodder trees leaves and seeds, commonly utilized in Sudan namely A. Senegal, A. torrtlis,A. mellifera, A. seyal, A. nilotica and Z.spina-chirsti in term of chemical composition and its relationship with the in vitro gas production characteristics. The chemical composition in term of Ash, ether extract (EE),crude protein (CP), acid detergent fiber (ADF), neutral detergent fiber and total condensed tannin (TCT) were significantly (p<0.001) varies among leaves and seeds. CP were ranged from 17.5% (Z.spina-chirsti) to 26.6% (A. nilotica) and from 19.45% ( A.torrtlis) to 38.69% ( A.Senegal) for leaves and seeds respectively. Total condensed tannin (TCT) content of leaves were significantly (p<0.001) higher than those of seeds it is ranged from 2.3% Z.spina-chirsti to 5.05% A. mellifera and from 0.45% Z.spina-chirsti to 4.19% A.mellifera respectively. Most of chemical composition were significantly correlated with gas production characteristics, ADF and TCT were correlated negatively with gas produced from fermentable part fraction (b) and the potential gas production (a + b), while CP correlated positively. Gas produced from fermentable fraction (b) and the potential gas production (a+ b) were significantly ( p<0.001) higher in seeds than in leaves 64.94ml and 54.98ml respectively for Z.spina-chirsti seeds and 39.79 ml and 39.18 ml respectively for A.mellifera leaves this may be due to their high content of CP and low content of TCT. Therefore, according to the potential gas production performance seeds were ranked higher than leaves. The higher values obtained for the potential gas production in the seeds will indicate a better nutrient availability for rumen microorganisms.
