| Abstract | ||||
| This study was conducted to investigate effect of dietary different levels of crude fiber on productive performance and economic efficiency for growing Domiaty ducks from 6 to 18 weeks of age and subsequent effect during laying period. A total number of 117 local growing Domiaty ducks (90♀+27♂), 6 weeks old were weighed and divided into three dietary treatments on design as follow: control diet with 3.5 % crude fiber while the other treatments were given higher levels of dietary crude fiber (4.77 and 6.23%) as a result of usage different levels of olive cake (OK). The results illustrated that dietary different levels of CF had no significant effect on body weight and body weight gain at the end of growing period. The same manner, no significant influence of dietary feed conversion ration. The diet included 6.23% CF recorded significantly the highest value of ether extract digestibility, on the other hand, two levels of CF resulted in a significant improvement in digestibility of crude fiber (CF) as compared to the control diet. Ducks fed control diet recorded significantly lower value of organic matter (OM) digestibility than those received diet contained 4.77% CF. Nitrogen retention was significantly increased by the diet with 4.77 and 6.23% CF compared to the control diet. The dietary different levels of CF lead to significantly higher HDL and ratio HDL/LDL than control. The ducks fed diet contained 4.77% CF reached to sexual maturity (SM) at earlier age (145 days) than control group by 8 days which reached to SM at 153 days. The diet with 4.77% CF significantly improved egg number/duck as a subsequent effect compared to control diet. It is noted that total embryonic mortality was decreased as a result from the previous grower diet contained 4.77% CF by about 9.9% and there are improvement in hatchability of fertile eggs produced from ducks fed the same diet by about 2.26% compared to the control diet. It could be concluded that the grower Domiaty duck's diet which contained moderate levels of CF (4.77 and 6.23%) did not have any harmful impact on productive performance and the diet with 4.77% CF can be used to maximize productive, reproductive performance and economic efficiency as a subsequent impact during laying period. | ||||
