|
|
Abstract: This study was conducted to evaluate the effect of adding Yucca Schidigera powder (Y.P) at levels of 50,100,150 and 200 mg/kg of rabbit diets as feed addittive on growth performance, carcass traits, blood parameters and economical efficiency. A total of 60 growing rabbits, 6 weeks of age, were divided into 5 dietary treatments of 12 rabbits each in three replicates (5×3×4).The diets were formulated to be iso-nitrogenous (18.02% Crude protein) and iso- energetic (2752 kcal DE/kg diet ).The experiment was terminated when rabbits were 14 weeks of age. Weight gain, feed intake, and feed conversion were calculated. At the end of the experiment, some blood plasma constituents and carcass characteristics were measured. Results showed that addition of Yucca Schidigera powder (Y.P) at level of 100 mg/kg of rabbits diet, significantly improved the final body weight, body weight gain, feed conversion and globulin level, red blood cells, white blood cells counts, packed cell volume in the blood plasma. Also, decreased abdominal fat and proved to be more economical than the other treatments and the control group.
Key words: Yucca, schidigera, saponins, performance, rabbits.
