Abstract

A study to evaluate effect of toasting duration on proximate nutrient composition of Bambara nut sievate (BNS), growth response and cost-benefit of weaned mongrel rabbits fed dietary inclusion of BNS supplemented with Tridax procumbens. Raw BNS (5kg) was mixed with water (500 ml) and toasted thrice at three different durations (20, 30 and 40 minutes) at 50 -60°C. Thereafter, allowed to cool and analyzed for proximate nutrient composition, while metabolizable energy (ME) was calculated. Thirty (30) weaned rabbits (554.00 to 555.00 g) were allotted to 5 treatments of 6 rabbits with each rabbit serving as a replicate in a completely randomized design. Five diets were formulated using 20 kg each of BNS; T1, T2, T3, T4 and T5 to contain 0, raw BNS, BNS toasted for 20, 30 and 40 minutes, respectively. Growth response data used were feed intake (DFI), weight gain, FCR and mortality. Cost- benefit analysis was evaluated using cost per kg diet, cost of feed consumed, cost per kg weight gain, total cost of production and profit. Data were subjected to one-way analysis of variance (ANOVA) using SPSS. Results revealed that Raw and BNS toasted for 40 minutes had the highest and similar ME (2625.94 Kcal/Kg) while BNS toasted for 30 minutes recorded the lowest ME (2260.87 kcal/kg). DFI of rabbits fed BNS diets was highest (71.17 g) and lowest (60.57 g), on the control diet. Rabbits fed raw BNS diet had zero (0%) mortality. Cost per kg diet (?203.34) was highest for rabbits on control diet. Rabbit fed diet containing BNS had the highest profit (?602.74). It can be concluded that toasting BNS for 40 minutes improved ME, inclusion of 20 kg of BNS in rabbits’ diet improved feed intake, healthiness (raw BNS) and profit.
