Chemical composition and nutritive value of kapok seed meal for broiler chickens

Abstract

1. Mechanically extracted kapok (Ceiba pentandra) seed meal (KSM) contained 324 g crude protein, 97 g ether extract, 289 g fibre, 94 g ash, 128 g available carbohydrates, 3·8 g calcium, 11 g phosphorus, 10·4 g cyclopropenoid fatty acids and 15 g tannins per kg. 2. In a 4 × 2 factorial experiment, KSM was incorporated in broiler starter and finisher feeds at 0, 30, 60 and 90 g/kg, replacing sunflower meal (SFM) w/w; without and with multi-enzyme supplementation. 3. No significant differences were noticed between treatments in body weight gain, feed consumption, feed conversion efficiency, mortality or carcase yields. 4. Multi-enzyme (amylase, endoxylanase, hemicellulase, β-glucanase, pectinase, phytase and protease) supplementation did not improve the growth performance of broilers fed on the KSM diets.
