Abstract

Effect of the varieties of black pipper powder (photobiotics) and biobiotic (probiotic) in improving the quality performance and traits of egg layers .Used 128 layer 25 weeks age were randomly assigned to 8 treatments with 4 replicates of 4 hens housed in the pen (replicates) and each treatment included four replicate. The period of this experiment were 90 days . Fed and water was ad libitum and the treatments of this study were : T1: (basal diet) , T2:basal diet contained 1%of powder of the dehulled black piper seeds, T3:1% black indian piper seeds ,T4: 1% malaysian black piper seeds , T5:0.1% probiotic ,T6: 1% dehulled black Indian piper seeds + 0.1% probiotic, T7: 1% black indian piper seeds + 0.1% probiotic and T8: 1% malaysian black piper seeds + 0.1% probiotic .The results of the statistical analysis showed significantly(p≤0.05) higher average of the egg production(H.D%) for the birds of the T5 and T8 by comparing that with T6 treatment birds. There were no significant differences(p≤0.05) among the all treatments for the egg weight average, while the average of the egg mass were significantly(p≤0.05) heavier for the birds of the T4, T5, T7 and T8 comparing with the T6 birds. The average of feed conversion ratio for the T5 birds were significantly(p≤0.05) better than birds of the T4 and T6, while the birds of the T1,T5, T7 and T8 significantly(p≤0.05) were best the birds of T6 in the ability of energy, protein, methionine and lysine conversion ratio to the egg. No significantly(p≤0.05) variance among the treatments in the external, internal quality traits, egg sensory traits and the percentage weights of the internal organs.The economic return as feed cost the production of one kilogram egg was the best for the fifth treatment.
