3.1 Location and Duration of Study
The experiment was conducted at the Rabbit Unit of the University of Port Harcourt Research and Demonstration Farm, Choba, River State and lasted for 60 days
3.2 Experimental Animal and Management
Twenty four (24) dutch-breed of weaned rabbits 6-7 weeks old and weighing 463g on average were used, randomly allotted to four dietary treatments of A, B, C and D in a Completely Randomized Designed (CRD). Each treatment group was further sub-divided into three replicate of two rabbit each. The Jatropha leaf meal was incorporated in the diet in the ratio, 0g, 0.50g, 0.70g and 0.90g in treatment A, B, C, and D respectively. The animal were given feed and water ad-libitum. The animal were administered

The leaves were harvested, washed and oven dried at 100oc for two hours and grinded to powdery form for easy interaction with the concentrate. Concentrate diet was formulated and kept in a clean and protected bag to avoid any spoilage or contamination during the experiment. The dietary treatments consist of a control and three graded level of Jatropha curcas leaf meal representing A, B, C and D…show more content…
The spleen also shows significant difference in T1 (202g) having the highest spleen weight and T3 (172g) having the lowest spleen weight.
4.5 Carcass Characteristics
Table 3 shows a significant difference of dressings percentage and dressed weight among treatments with T2 (56.54%, 594g respectively) having the highest percentage followed by T4 (48.58%, 514g respectively), T1 (44.58%, 404g respectively) and then T3 (36.95%, 292g respectively) having the lowest dressing percentage and dressed weight.
A significant (p>0.05) difference of the effect of jatropha leaf meal was observed in the weight of thigh and back fat along treatments. T2 (203g and 204g respectively) having the highest weight followed by T4 (200g and 197g rep), then T1 (152g and 138g rep) and T3 (94g and 118g rep) having the lowest thigh and back fat weight, while T2 (187g) is having the highest weight of shoulder followed by T4 (117g) and T1 (114g) having no significant difference and T3 (80g) having the lowest shoulder
