Abstract

This experiment was conducted to investigate the effects of feeding  fermented date  pite (FDP) on performance, carcass traits and ileal microbial population  in  broiler chickens. In a  2 ×4  factorial arrangement, 540 day – old broiler chicks were randomly assigned to one of nine experimental diets, each with five replicates containing 12 chicks each. Dietary treatments  included a corn- soybean meal – based diet (control), and diets containing  2, 4, 6 and 8%  raw date pit (RDP)  and 2, 4, 6 and 8 % fermented date pit (FDP). Fermentation process effectively decreased crude fiber and increased crude protein (p < 0.05).   Feeding fermented date pite increased feed intake and improved body weight gain in finisher period (25- 42 day) of the experiment (p < 0.05 ). In this period  birds fed FDP with level  8%  had  significantly (p <0.05 ) body weight  higher in comparison to chicks fed diet control ( 1474 gr vs 1336 gr ). Birds fed FDP had  feed cost higher compared to chick fed RDP (p<0.05). Abdominal fat and gizzard  was significantly lower in broiler fed FDP than to RDP (p <0.05 ). Lactic acid  bacteria  population  and coliform  in ileum of broilers fed diet containing  FDP  as  compared to RDP were  significantly higher and lower respectively (p<0.05). Results of this study demonstrated that fermentation date pite in level 8% led to performance improvement in broiler chickens during finisher period.
