Abstract
A study was conducted to evaluate the effect of boiled and fermented locust bean seeds as dietary inclusions on growth performance and carcass quality of weaner rabbits. Samples of raw, boiled and fermented seeds were taken to the laboratory for proximate composition and anti-nutritional factors evaluation using Association of Official Analytical Chemists (AOAC). The results of proximate composition of the seeds revealed that fermented seeds had significantly (P<0.05) high Crude protein, low Dry Matter (DM), low Crude Fibre (CF), Nitrogen Free Extract (NFE) andashthan raw and boiled seeds. Processing methods significantly (P<0.05) reduced phytic acid, saponins,tannin, cyanide and oxalate contents of seeds. The reduction was more significant (p<0.05) in the fermented seeds; phytate from 409.83% to 55.63%; saponins from 207.83% to 44.38%; tannin, 176.50% to 63.74%; cyanide, 87.83% to 68.38%; and oxalate, 181.83% to 68.17%. Four experimental diets were thereafter compounded; treatment 1 was the control while treatments 2, 3, and 4 were diets with raw, boiled and fermented locust bean seeds respectively. Twelve (12) % of the seed was included in the diets and the diets were compounded to be iso-caloric and iso-nitrogenous to meet the nutrient requirement of growing rabbits. A total of 20 weaner rabbits were used, five (5) rabbits per treatment with each serving as a replicate in a completely randomized design and the experimental diets were fedad libitum for eight (8) weeks. The results of the growth performance of the rabbits revealed that rabbits fed fermented locust bean seeds had significantly (P<0.05) better average daily weight gain (125.09g/wk), final weight (1312.50g) and feed conversion ratio (5.04) than the raw seeds. However, boiling of the African locust bean seeds significantly (P<0.05) improved palatability (protein) of the diet as animals on this diet consumed more feed compared to other treatments.
