Abstract:
The current study included two experiments, The labrotary experiment was carried out to investigate the effect of fermented barley with rumen liquor (10 , 20 ml / kg barley) at different inclusion periods (7 ,14 and 21 days) . The results of chemical analysis to crud protein , fat and ash percentage for fermented barley showed increased, and fiber percentage decreased on 10 and 20 ml rumen liquor at 14 days fermented period . The second experiment was included the effect of addition fermented barley by 20 ml rumen liquor for 14 days . A total of 360 unsexed one day old chicks were randomly distributed to eight treatments in three replicated ( 15 chicks/ replicate) . During the experimental period 35 days two diets were fed starter and grower .The treatments as follow : 1 - First treatment of control included 50% maize .2 - Second treatment included the replacement of barley in the rate of 25%. 3 - Three Treatment included the replacement of barley in the rate of 50%.4 - Fourth treatment included the replacement of barley in the rate of 75%.5 - Fifth treatment included the replacement of barley in the rate of 100%.6 - Sixth treatment included the replacement of barley in the rate of 25%+1 g enzymes/ kg feed7 - Seventh treatment included the replacement of barley in the rate of 50% + 1 g enzymes/ kg feed .8 - Eighth treatment included the replacement of barley in the rate of 75%+ 1 g enzymes/ kg feed.The results of this studies indicated that : 1. A significant increase(P <0.05) of mean body weights and body weight gains in T2 as compared with the control treatment while T3 and T4 showed non significant differences as compared with control .2. A significant increase(P <0.05) of accumulative feed consumption and feed conversion efficiency of T5 and T8 but T2 and T3 were given a least significant differences compared with control.3. Non significant increase(P <0.05) of dressing percentage for T2 , T3 and T4 as compared with control treatment . b 4. Treatments T2,T3 , T4 and T5 showed a significant differences (P <0.05) in relative weight of gizzard and cecum compared with enzymes treatments.5. A significant differences of hemoglobin of all treatments as compared with control , while glucose levels were significantly(P <0.05) increased in control and treatments treated with rumen fuid compared with enzyme treatments . but T1 and T2 showed highly significant (P <0.05) in cholesterol levels as compared with others .6. There were significant differences (P <0.05) in logartmic numbers of total bacteria, lactobacillus and bacteria degrading cellulose in rumen fuid treatments as compared with others.7. T2 , T3 ,T4 showed significant differences (P <0.05) in intestinal length as compared with others, while T3,T4,T5,T6,T7 and T8 showed a significant (P <0.05) increase passage rate compared with T1 and T2 .8. T2 and T3 recorded less significantly differences (P <0.05) in viscosity intestinal contain as compared with other treatments . 9. Treatments treated by barley fermented with rumen fuid showed a highly significant (P <0.05) in tibia length , tibia ash percentage , tibia calcium and phosphorus contains as compared with control and treatment treated with enzymes .10. A significant differences (P <0.05) in villus length and the ratio between the length and depth in all treatments as compared with control .11. No significant differences in all treatments as compared with control in the carcass quality .12. The economical benefits of the study fed barley fermented rumen fuid T2,T3,T4 and control showed significant differences (P <0.05) in production index and production coefficient as compared with enzymes treatments.
