Abstract
Roselle (Hibiscus Sabdariffa) seed meal was analysed for proximate composition and then fed to broiler chicks in two different trials. Roselle seed was found to contain 29.66% crude protein 22.15% crude fiber 16.87% ether extract and 7.01% Ash. Two experiments were conducted in the premises of poultry research unit of the Faculty of Animal Production, University of Khartoum. In experiment 1, 200 Arbor Acrs day old unsexed broiler chicks were equally divided into 20 pens. Four experimental rations were formulated containing graded levels of Roselle seed meal (RSM) (0.0%, 10%, 20% and 30%). The four diets were randomly allocated to the pens; 5 pens/ dietary treatment. Feed and water were provided ad libitum throughout the six weeks experimental period. In experiment 2, 150 Arbor Acrs day old unsexed broiler chicks were used. Three rations were formulated containing graded levels of RSM (0.0%, 10%, and 20%) at the expense of groundnut meal. Parameters measured were feed intake, body weight gain, feed conversion ratio and dressing and shrinkage percentages. The results of experiments revealed that inclusion of 20% and 30% of RSM reduced the feed intake and body weight gain during the first three weeks. After four weeks of age, the birds adapted to RSM and compensated for the reduction in feed intake and body weight gain that occurred before four weeks of age. Results of these experiments suggested that RSM can be included up to 30% in broiler rations without any adverse effects especially when used as a finisher diet.
