Chemical evaluation in vitro and in sacco of traditional fodder tree (Delonix elata Gamble) in buffalos

Abstract

Present study was undertaken in order to study Delonix elata (L) Gamble for its nutritive value so as to use this particular tree leaves as livestock feed. The findings shown that, Delonix elata (L) Gamble contained, 32.8, 90.9, 25.2, 2.4, 18.2, 9.1, and 45.1% of DM, OM, CP, EE, CF, TA and NFE, respectively. The cell wall constituents (%) were, 46.5 (NDF), 24.3 (ADF), 22.2 (hemicellulose) and 5.3 (ADL). The determination of different fraction of carbohydrates and protein as per CNCPS (Cornell Net Carbohydrate and Protein System) revealed that, carbohydrate fraction A and protein fraction B2 contents were more, indicating the readily available nutrients are more in this forage. The IVDMD and IVOMD were 76.7 and 77.4%, respectively. In sacco DM degradability indicated readily soluble component a-14.3, insoluble but degradable component, b-68.7, rate constant at which ‘b’ is degraded c- 0.0586 and effective degradable dry matter (EDDM) of 55.8%. While the protein degradability study indicated a-18.3, b-60.4, c- 0.0904 and effective degradable protein (EDP) was 60.8%. The total tannin content was 4.1 g%. It can be concluded that, Delonix elata can be used as livestock feed.
