Effect of different dietary fiber levels on reproductive and economic performance of sinai local, strain cocks

Abstract: The present study was carried out to investigate the effect of different dietary fiber levels in local Sinai cocks diets on the reproductive and economic performance during the period from 15-40 wks of age. Eighteen Sinai cocks were randomly assigned to different levels of crude fiber. The basal diet contained 3.65% crude fiber and the experimental treatments were given higher levels of crude fiber as a result of usage different levels of sunflower meal, olive cake and combination between them. While, all hens (180 female) were fed layer diet contained 17% crude protein and 2750 Kcal/Kg diet ME. Results of the current study are summarized as follows:
1. The cocks fed diet contained 5.9 and 4.65% CF (14 and 7% SFM) recoded the lowest live body weight, and also resulted in a significantly decrease (p<0.05) in body weight gain compared to the control diet.
2. The mass motility of sperms was significantly increased (p<0.05) by about 16.28% of males fed diet contained 6.02 % CF (7% SFM+5%OK) comparing with control diet.
3. Both progressive motility and sperm concentration were improved by increasing dietary CF from 3.65% (control) to 6.02 % (7% SFM+5%OK).
4. The fertility% was significantly improved (p<0.05) in eggs from hens that were inseminated by cocks fed diet contained 5.9% CF (14% SFM) by about 7.89 % compared to the control diet.
5. The hatchability of set eggs % was significantly increased (p<0.05) by feeding diet contained 5.9 5% CF (14% SFM) comparing with the control diet followed by those.
fed diet with 5.45% CF and 4.77% CF (7% SFM and 5% OK).
6. The diets contained 4.77 and 6.02% CF (5% OK and 7% SFM +5 % OK) resulted in a significant increase (p<0.05) the hatchability of fertile eggs % by about 3.38% as compared to the control group.
7. The diet contained 5.95 CF (14% SFM) resulted in significantly improved (p<0.05) economic efficiency of hatchability of set eggs compared with the control diet.
The present study illustrates that local Sinai cocks require a moderate levels of crude fiber in diets ranged from 4.65 to 5.95 % from (5 % Ok, 7% and 14% SFM) during the period from 15 to 40 weeks of age for optimal the reproductive and economical performance.
