| Abstract | ||
| The present experiment aimed to study the effect of diet supplementation with probiotic, prebiotic and synbiotic on layer performance of White Leghorn (WL) laying hens. Alocally prepared probiotic were used each one gram of this probiotic contain at least 1010 Colony Forming Units of Bifidobacterium bacteria and Saccharomyces cerevisiae yeast and Aspergillus niger fungal respectivally. The Prebiotic used in this study were consist a non starch oligosaccharide of S.cerevisiae yeast after crashing of cell wall.The synbiotic used in this study were prepared by mixed un equael amount from probiotic (Iraqi probiotic) and prebiotic. Atotal of 180 WL laying hens, 16 weeks old were randomly allocated into four treatment groups. Hens in T1 group were fed a standerd laying diet and used as control group. Hen in T2, T3 and T4 were fed diet supplement with 5 Kg / ton of probiotic, prebiotic and synbiotic respectively. The experiment was conducted in poultry farm at Agriculture College – University of Baghdad for the period from 27th May 2005 to first of Jully 2006. Egg production were measured monthly throw out of the experimental period. The three kinds of feed supplementation were improved the means of egg production (Hen Day%, Hen House%) and egg mass and accumulative egg production compared with control. The accumulative eggs production were 243.1, 256.1, 254.8 and 249.6 (egg / chicken / year), accumulative egg mass were 14.59, 15.32, 15.13 and 14.67 Kg egg per hen for the four treatment group respectively. Dietary treatment seemed to had asignificant (P<0.01) effect on feed consumption. The accumulative feed consumption were significantly (P<0.01) decreced with synbiotic supplementation treatment (T4) when compared with other treatments. | ||
