The Improvement of Laying Productivity and Egg Quality according to Providing Germinated and Fermented Soybean for a Feed Additive

This study was performed to investigate the effects of laying productivity and egg quality according to providing germi-nated and fermented soybean (GFS) as feed additive. Among the strain, we selected Monascus purpureus KCCM 12002 so that inoculated in soybean and fermented for 48 h at 20oC. A total of two-hundred forty 70-wk-old Hy-Line Brown layers were divided into four groups (4 treatment×6 replication×10 birds each) and fed diets containing 0 (as control) (T1), 0.5% (T2), 1.0 % (T3) or 2.0 % GFS (T4) for 6 wk. The laying productivity, egg quality and blood property in the egg yolk were experimented. There were no significant differences in the laying productivity, relative liver and spleen weights, egg yolk color and eggshell strength among another groups. The eggshell color, eggshell thickness and haugh unit significantly increased in the GFS-supplemented group (p<0.05) compared to control. However, no significant differences were observed in the blood property after supplementation. The amount of lactic acid bacteria present during storage increased by provid-ing of GFS (p<0.05) compare to control group. Our study results suggested that GFS can be used as a favorable feed additive and feedstuff for the productivity of high quality eggs and promoted relative industry
