dc.description.abstractChemical analysis, apparent metabolizable energy and one feeding trial were conducted to assess the nutritional value of jackfruit seeds that had been subjected to a combination of soaking, boiling, followed by fermentation. In the feeding trial, five broiler starter diets were formulated with the processed jackfruit seed meal constituting 0, 80, 160, 240 and 320 g/kg of the diet. The jackfruit seeds before and after processing contained 151, 140 g crude protein; 740, 747 g total carbohydrates; 11.1, 1.28 g tannins; 10.0, 1.47 g total oxalates per kg respectively. The apparent metabolizable energy value of the processed jackfruit seed meal was 2368±315 Kcal/kg. Inclusion of the processed jackfruit seed meal affected chick growth, nutrient utilization and organ weights relative to body weight. At 80 and 320g/kg inclusion, weight gain and feed/gain were depressed by 5.2, 42.1%; 6.2, 40.7% respectively. Feed intake was not affected up to 240 g/kg inclusion but reduced by 18.3% at 320 g/kg. Except for gizzard; weights of liver, caecum, heart, intestines and pancreas were affected. At 80 and 320 g/kg inclusion; weights of caecum, intestine, pancreas and gizzard increased by 69.4, 113.9%; 4.5, 43.2%; 7.3, 46.3%; 11.3, 14.6%, while liver and heart were reduced by 7.7, 22.2%; 27.9, 34.2% respectively. Apart from nitrogen retention; nitrogen digestibility, dry matter digestibility and excreta water content were not affected. Nitrogen retention increased by 38.5% at 320 g/kg inclusion. Processing reduced tannins and oxalates from jackfruit seeds by over 85%. The processed jackfruit seed meal can be included in poultry diets at levels up to 80 g/kg without compromising with: feed intake, feed efficiency, daily weight gain and nutrient utilization. Although the cost per kg gain of birds increased with jackfruit seed meal inclusion, the seeds will eventually be readily available at low or no cost. However, for economic efficiency the cost of collection and treatment should be put intconsideration.
