The potential for the utilization of Mucuna seeds as an alternative source of protein was evaluated by presoaking in water then in sodium bicarbonate solution + boiling treatment on the one hand and isolating protein technique on the second hand on the growth and hematological performances of broilers. A total of 135 one-day-old Cobb 500 broilers, divided into three groups of 45 animals each were randomly allocated to three treatment diets with 3 replicates (n=15/replicate) each per treatment and fed ad libitum with three iso-protein diets: Diet 1 (RTS) given to the Control batch contained soya bean meal and this principal protein source was completely replaced by M. pruriens seeds meal in Diet 2 (RFM) and by protein isolated from M. pruriens in Diet 3 (RIM) given to batches 2 and 3 respectively. Results revealed that FI, ADG, PER, Carcass yield, Hb and Hct were comparable but significantly (p<0.05) low in broilers fed RFM (77.01 g/26.16 g/1.99/68.69%, 11.98 g/dL/28.46% respectively) and RIM (76.98 g/25.88 g/2.08/67.61%, 12.05 g/dL/28.28% respectively) diets and also in all characteristics of the digestive tract. The inverse trend i.e. highest (p<0.05) but comparable values of Heart (0.74 g/RFM; 0.77 g/RIM) was observed in these same animals; Birds fed RIM diet registered the lowest (p<0.05) BWG (711.04 g) and LW (799.65 g) but the highest (p<0.05) FCR (3.45). These results suggest that meal and protein isolate of M. pruriens seeds could be valorised in broiler diet subject to further investigations in growth-finishing phase.

Mucuna pruriens (velvet bean) represents an interesting source of protein poorly studied. The effect of dietary inclusion of meal and protein isolate of Mucuna seeds on biochemical and oxidative stress parameter of broilers (135-one-day Cobb 500 chickens) was investigated. Three isonitrogenous diets were formulated from soya bean meal (Control group: RTS), Mucuna meal (coded RFM) and Mucuna protein isolate (coded RIM). Each of the dietary treatments was triplicated with 15 birds per replicate in a completely randomized design. The birds were offered feed and water ad libitum. The results revealed significant (p < 0.05) effect of N source on the organ total proteins with treatment RFM and RIM exhibiting lower but comparable levels in the Liver (2.01 and 1.98 g/dL), Heart (1.95 and 1.89 g/dL) and Kidney (1.92 and 1.91 g/dL). Triglycerides contents were significantly (p < 0.05) higher in the liver of broilers fed RIM and RFM (2.49 and 2.36 mg/dL), in the Kidney of chicks fed RIM and RTS (2.27 and 2.34 mg/dL) and in the Heart of birds fed RTS and RFM (1.90 and 1.87 mg/dL). Broilers fed RFM presented the highest (p < 0.05) Liver total cholesterol (1.61 mg/dL) and ALAT contents but with similar values with birds fed RTS (36.43 and 35.50 UI/L respectively). ASAT level was significantly high (p < 0.05) in the Liver and Plasma (265.50 and 264.50 UI/L respectively) of broilers of RFM diet. In all the organs, MDA content was highest (p < 0.05) in chicks of RIM batch. In the Heart and Plasma, chicks of RFM (3.23 and 5.05 µl/mg respectively) and RIM (5.45 and 5.35 µl/mg respectively) diets registered elevated rate of CAT. In view of these results, investigations remain to be carried out on the impact of the inclusion of

A study was conducted on 48 guinea pigs (24 females: 522.21±28.88g and 24 males: 566.75±43.13g) of local breed of Cameroon to evaluate the mineral content of their meat. Animals were fed with Pennisetum purpureum ad libitum supplemented with one of the experimental diets: ML 0% (Control), ML 8%, ML 10% and ML 12% containing respectively 0, 8, 10 and 12 % of cassava leaf meal (CLM). Each of the 4 diets was assigned to 4 groups of animals corresponding to the 4 treatments/Diets and these animals were distributed in a completely randomized design with 12 replicates per ration, six of which were per sex and per group. After sacrifice of animals at 22nd weeks, the meat from the Loin, Thigh and Shoulder, were analyzed. Results revealed that mineral contents of females meat were higher than those of males: Sodium content was highest (p<0.05) in the Shoulder (48.34%) of females fed Control diet; Females fed ML 12% diet registered at Shoulder’s level higher (p<0.05) concentrations of Calcium and Iron (14.64 and 46.78 % respectively) just like in the same part, Potassium and Zinc contents were the most (p<0.05) abundant (9.49 and 4.11% respectively). This study revealed that guinea pig’s meat is particularly poor in Magnesium (0.95%). The greatest (p<0.05) Iron content was at shoulder’s level (46.78 mg / gDM) of females receiving ML 12%. These results suggest that CLM can improve mineral content of guinea pig’s meat.
