| Abstract |
A factorial design experiment (5x3) was carried out including five levels of olive pulp (0,4,8,12 and 16%) and three levels of supplemented optizyme (0,0.5 and 1.0 g/kg diet).
A total number of 675 Hubbard chicks were used in this experiment. Chicks were randomly distributed into 15 treatment groups (3 replicates each). Chicks in all treatments were equal in number and have nearly similar initial body weight.
Results obtained showed that chicks fed diets containing olive pulp up to 16%significantly improved live body weight at 4 weeks of age, daily weight gain at 2-4 weeks of age and daily feed intake during all the experimental periods as compared to the control one. Feed conversion values were significantly (P<0.05) affected by dietary olive pulp during the starter period (2-4 weeks), finisher period (4-7 weeks) and the whole experimental period (2-7 weeks). Growth performance traits of broiler chicks were significantly (P<0.05) affected by different dietary optizyme levels except for feed conversion at 4-7 weeks of age. The highest improvement of most growth performance traits were observed for chicks given 8% olive pulp with 0.5 g optizyme/ kg feed. Carcass traits at 7 weeks of age were not significantly affected by olive pulp level, enzyme supplementation levels or the interaction between olive pulp and enzyme level.
Conclusively, it could be recommended to use optizyme supplements (0.5g/kg feed) with 8% olive pulp level in starter and finisher broiler diets. Such practice may be of high economical value without any adverse effects on the performance of broiler chicks up to marketing age.
Keywords: broiler chicks, olive pulp, optizyme, growth performance, carcass traits.
