摘要

Legume seed products are used extensively in human and animal nutrition, but high levels of inclusion are often avoided as their secondary compounds can interfere with digestion and absorption of nutrients in the digestive tract. Due to the well-known benefits of some physicochemical treatments on nutritional value, this experiment was completed to assess effects of soaking and heat treatment on the nutritional value of dehulled and hulled X'pelon seeds (Vigna unguiculata (L.) Walp) to Nile tilapia (Oreochromis niloticus) fingerlings. Seeds were soaked for 16 h in a 2 g/kg sodium bisulphate solution in water. Seeds were divided into two lots, being hulled and dehulled. Three heat treatments were used to convert the seeds to meal, being 5 h of hot air flow (70 degrees C); autoclaving at 119 degrees C for 30 min to 1.05 kg/cm2, and 7 h in a forced air oven at 48 degrees C. The resultant crude protein (CP) quality of each meal was evaluated by amino acid analysis and by a tilapia feeding study in which fingerlings were fed one of eight diets, each containing 350 g CP/kg of DM, of which seven diets were formulated with 0.80 of CP provided by fish meal and 0.20 by the X'pelon meals and one control diet was formulated with fish meal as the sole CP source. The study encompassed 9 weeks during which fingerlings were fed ad libitum. Chemical and secondary compound analysis of treated seeds showed that heat flow reduced phytic acid by 34.9% and trypsin inhibitors and hemaglutinin decreased by 94.5%, while complete elimination was obtained with autoclaving. Soaking and heat treatment are suitable for partial or complete elimination of the secondary compounds of X'pelon seeds without affecting the content and bioavailability of amino acids, with heat treatment by hot air flow the best. Partial replacement of fish meal with X'pelon meal improved growth and feed efficiency of Nile tilapia, whether the meal was treated or raw.
