AbstractThe present experiment aimed to study the effect of diet supplementation with probiotic, prebiotic and synbiotic on fertility, hatchability and chicks produced of White Leghorn (WL) laying hens.
Alocally prepared probiotic were used and each gram of this probiotic contain at least 1010 Colony Forming Units of Bifidobacterium and L. actibacillus bacteria and contain 108 CFU from Saccharomyces cerevisiae yeast and Aspergillus niger fungal respectivally . The Prebiotic were used in this study consist a non starch oligosaccharide of S.cerevisiae yeast after crashing of cell wall .The symbiotic were used in this study prepared by mixed un equael amount from probiotic (Iraqi probiotic) and prebiotic. Atotal of 180 laying hens and 24 cockes WL , 16 weeks old were randomly allocated into foure 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 symbiotic 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 inter hatchery at age 45 , 49 and 53 week throughout of the experimental period.
Feed supplementation with Probiotic ,Prebiotic and Synbiotic were significantly improved (P<0.01) hatchability , fertility , chicks produced from hen and feed conversion (g / chick) as compared with control.
