Characterization of the Chemical Composition of Raw and Treated Jackfruit (Artocarpus Heterophyllus) and Java Plum (Syzygium Cumini) Beans for Poultry Feeding
Journal Title: Journal of Animal Science Advances - Year 2014, Vol 4, Issue 11
Abstract
The chemical composition of Jackfruit beans (JFB) and Java plum beans (JPB) was investigated to establish their nutritive value for poultry. The beans were soaked in water before subjecting them to the following treatments: fermented in presence of wood ash (SFWA); boiled (SB); roasted (SR); autoclaved (SA); fermented after boiling (SBF); roasted after fermentation (SFR); and a combination of boiling, fermentation and roasting (SBFR). Screening to identify phytochemical compounds and quantify anti-nutrients in the raw beans; determining the content of anti-nutrients in treated beans were conducted. Additionally, proximate composition, minerals, and metabolisable energy (ME) of raw and treated beans were determined. Most (>70%) phytochemical compounds in raw JFB and JPB were anti-nutrients and included sterols, triterpenes, courmarins, tannins, cardiac glycosides, alkaloids, saponins and steroid glycosides. Raw JFB and JPB had 1.11, 2.44% tannins; 1.00, 1.54 % oxalates; 0.754, 0.714% phytates respectively. Tannins in raw JFB were reduced by 88.7, 88.5, 85.9 and 84.5% in SFR, SBF, SB and SBFR treatments respectively. Oxalates in JFB were reduced by 85.3% and 81.2% in SBF and SBFR treatments respectively. Proximate composition, minerals, and ME of raw JFB and JPB was 92.5, 91.0% DM; 15.1, 4.42% CP; 0.983, 0.400% EE; 4.20, 3.44% CF; 3.78, 2.17% ash; 74.0, 88.6% NFE; 13.3, 13.2 MJ/kg ME; 0.456, 0.430% Na; 0.611, 0.481% Ca; 0.222, 0.088% P; 1.53, 0.895% K respectively. The method of treatment had no effect (P˃0.05) on CF of JFB. Method of treatment had a significant (P˂0.05) effect on CP, NFE, ME, DM, ash, P, K, Na, and Ca for JFB. Method of treatment had no significant (P˃0.05) effect on CF and CP for JPB but DM, ash, EE, NFE, ME, P, K, Na, and Ca were affected (P˂0.05). The SBF and SBFR reduced tannins and oxalates from raw JFB by more than 80%. The major nutrient in JFB and JPB is energy.
