Assessment of Nutritional Quality and Value Addition of Ripened Jackfruit for Poultry Feed

Abstract

The present study was conducted to evaluate the nutritive value of ripened jackfruit collected from different market of Thakurgaon, Sylhet & Chittagong region. A total of 50 samples were analyzed to evaluate the chemical composition and metabolizable energy content of jackfruit. After breaking, the ripened jackfruits were divided into four parts: jackfruit body (43.08%), seed+exocarp (8.99%), seed–exocarp (7.13%) and exocarp (1.86%) and analyzed them separately. The nutritive value of jackfruit body was also analyzed and found accordingly, DM (98.70%), ME (2310.25 kcal/kg), CP (12.6%), CF (27.5%), NFE (44.90%), EE (6%), Ash (7.72%), Ca (1.59%), & P (0.26%). The nutritive value of seed without exocarp were DM (97.80%), ME (2931.52 kcal/kg), CP(15.7%), CF (6%), NFE (71.86%), EE (1.02%), Ash(3.22%), Ca (1.20%), & P(0.28%) while the contents of jackfruit seed+exocarp were DM (98.12%), ME (2827.65 kcal/kg), CP (14.0%), CF (9.50%), NFE (70.34%), EE (1.05%), Ash(3.22%), Ca (1.15%), & P (0.43%). In addition the Exocarp possesses DM (98.50%), ME (1589.06 kcal/kg), CP( 10.5%), CF (48%), NFE(36.16%), EE (1.09%), Ash(2.75%), Ca (1.10%), & P (0.20%). The nutrient contents of different parts were found significantly (P<0.01, <0.05) different. The CP content of seed without exocarp was highest (15.7%) in comparison with others parts of the fruit while the lowest in exocarp (10.50%). Moreover, the ME, CF, EE and NFE contents also differ significantly (P<0.01). The study was conducted with the aim of using surplus jackfruit in summer season as poultry feed and to compare its nutritional value as a supplement in poultry diet. So, the different parts or as a whole ripened jackfruits may be used as a supplement with value addition in poultry ration formulation.
