Abstract
This study was planned to evaluate varying dietary calcium (Ca) and phosphorus (P) levels effects on the productive performance of Sudani ducklings during the growth period. A total of 240 unsexed ducklings, 7 days-old were split into four empirical groups, each of three replicates (20 ducklings each). The ducklings in the 1st up to the 4th group fed diet contained Ca plus P levels as follows 0.70% Ca+0.35% P (T1), 0.85% Ca+0.40% P (T2, as a control), 1.0% Ca+0.45% P (T3) and 1.15% Ca+0.50% P (T4), respectively during the starter and grower periods. Ducklings in T4 group recorded a significant improvement of live body weight, body weight gain, and feed conversion ratio compared to the ducklings in T1 groupat 7-91 days-old period. Both eviscerated carcass and total edible parts (%) were ameliorated (P>0.05) by increasing levels of Ca and P. All hematological parameters not significantly affected except for hemoglobin, which decreased by increasing levels of Ca and P. Serum Ca, P, vitamin D and alkaline phosphatase content for ducklings were not differed by varying Ca and P levels. Duckling's tibia calcium content significantly augmented by mounting Ca and P levels; however, their content from P not affected. From the obtained results, it could be concluded that the necessity to use the diet containing 1:1.15 Ca with 0.45: 0.50 P (%) to achieve the best growth characteristics and the ratio of edible parts, as well as tibia Ca content for Sudani ducklings during the growing period.
