Evaluation and Nutrient Quality of Detoxified Jackbean Seeds, Cooked in Distilled Water or Trona Solution, as a Substitute for Soybean Meal in Nile Tilapia,Oreochromis niloticus, Diets

Abstract

Jackbean, Canavalia ensiformis, seeds were detoxified using eight different wet thermal detoxification methods in either distilled water (5% w/v) or trona (NaCO 2 .NaHCO 3 .2H 2 O) solution. The effects of the detoxification methods on hemagglutinating, antitryptic and urease activities, and on the digestibility coefficient of crude protein and gross energy in the jackbean seeds were investigated. Cracked jackbean seeds cooked (100°C) in trona solution for one hour proved to be more effective as a method of inactivating the antinutritional factors in jackbean seeds. Dried detoxified jackbean seed meals were incorporated in dry practical diets providing 20% or 30% of total protein and fed to Nile tilapia, Oreochromis niloticus, fingerlings (mean weight, 6.7 g) twice daily to apparent satiation for 70 days. Mortality was low and no abnormal fish behavior was noted even when the detoxified jackbean meals provided 30% of total protein in diet. Growth and feed utilization indices, were similar (P Ͼ 0.05) between the diet in which cracked jackbean seeds cooked in water provided 20% of total protein and in diets in which cracked jackbean seeds cooked in trona solution provided 20% or 30% of total protein.

Response of African Catfish, <i>Clarias gariepinus</i> (Burchell 1822), Fingerlings Fed Diets Containing Differently Timed Wet-Heat-Treated Sesame (<i>Sesamum indicum</i>) Seedmeal

“…[35] reported good growth performance that was not significantly different from control was recorded when Clarias gariepinus was fed diets containing autoclaved nor roasted winged bean (Psophocarpus tetragonolobus) replacing up to 80% of fishmeal. Similarly [13] reported that 60% of soybean meal protein could be replaced be replaced with Rosselle (Hibiscus sabdariffa) seed meal without affecting growth performance and nutrient utilization in Clarias gariepinus. [21] reported that it is possible to replace soybean meal in Clarias gariepinus diet with cooked and mechanically defatted sesame seed meal with optimum growth response at a 25% replacement level though at 50% replacement with sesame seedmeal the growth response was different from that of control however it was similar to that of fish fed diets containing cooked and mechanically defatted sesame seed meal at a 25% replacement level with soybean meal.…”

“…In the recent past, researches were mostly focused on the under-utilized plant proteins in fish diets. Prominent among which are soybean meal [8] [9], groundnut cake [10], Lima bean [11], Jackbean [12] [13], African Yam bean [14], Pigeon Pea [15]. Relatively, work on the use of other oilseeds residue such as sesame meal in warm water fish nutrition is limited [16].…”

“…Protein digestibility was increased (P<0.05) in the PC in comparisons to raw Canavalia where ASOL-H did not showed any deleterious effect (P>0.05) ( (Fagbenro et al, 2004) have found no change in the energy value of Canavalia fed to Nile tilapia by means of the elimination of antinutrients cooking cracked seeds at 100°C for one hour.…”

“…Currently, it is widely planted in several region of Indonesia (Lenkala, 2014;Sridhar & Seena, 2006;Wahyuningsih & Saddewisasi, 2013). Unlike Mung Bean, which is widely used in Indonesia as Tempe, Jack Bean is only utilized as animal feed and its younger form is processed as vegetable (Winarni & Dharmawan, 2016;Sridhar & Seena, 2006;Fagbenro et al, 2004).…”
