| Abstract |
Feeding trails were conducted with White Pekin ducklings to evaluate the use of locally produccd olive pulp regarding duck perfonnance, some carcass traits and blood constituents. A total number of 225 (one week old) White Pekin ducklings were used and divided into five equal groups of 45 ducklings each. They were fed isonitrogenous and isocaloric diets containing 0,4, 8, 12 and 16% olive pulp during starter and finishing period.
Results obtained should that ducklings fed diets containing 12 and 16% olive pulp signifkantly (P<0.05 or P<0.01) improved live body weight at 8 weeks of age and daily weight gain, during 1-4 and 1-8 weeks of age than the other treatments. Feed intake of ducklings fed 12% and 16% olive pulp rations were significantly (P<0.05 or P<0.01) higher during 4-8 and 1-8 period than those fed either 4 and 8% or the control ration. The best feed conversion values (feed / gain ratio) was found with ducklings fed 4, 12 and 16% olive pulp, while the worst value was observed for those fed diet with 8% olive pulp during 4-8 and 1-8 weeks of age. Moreover, it was observed that the least feed cost / kg gain and the best economical cflicicncy values during all the experimental periods were recorded for birds fed 16% olive pulp .
Furthermore, feeding Pekin duckling 16% olive pulp ration resulted insignificant improvement in carcass traits (Giblets, abdominal fat, carcass and dressing). The components serum indicate that triglycrides and cholesterol were decreased significantly (P< 0.05) with increasing olive pulp levels up to 16%.
In conclusion, fi-om nutritional and economical points of view, the olive pulp could be used successfully and safety up to 16% in teeding White Pekin ducklings without adverse eflect on growth performance and carcass characteristics However, more studies are required to establish the economical optimum levels of more incorporation than l6% olive pulp in the White Pekin ducklings ration.
Key words: Olive pulp, (ducklings, performance, carcass traits, blood constituents.
