Objective: This study was conducted to investigate the supplementary effect of a phytogenic blend (SPA: a mixture containing fermented Schisandra chinensis pomace, fermented Pinus densiflora needle extract, and Allium tuberosum powder in the ratio of 2 : 2 : 1) on egg production, egg quality, and blood and visceral organs properties in laying hens. Methods: A total of 135 Hy-line brown laying hens (48-wk-old) were randomly allocated to three dietary treatments with 5 replicates of 9 hens. The control group (CON) was fed a basal diet (no exogenous SPA addition) and the experimental groups were fed the basal diet containing SPA at the level of 0.1% and 0.3% for 6 weeks. Results: The feed intake was significantly improved in SPA supplemented groups as compared with the control (p < 0.05). However, egg production, daily egg mass, and feed conversion ratio were not different among the dietary treatments (p > 0.05). For egg quality traits, only Haugh unit (HU) was significantly improved in SPA (0.3%) (p < 0.05) as compared with other groups. However, HU was not affected during 4-wk of storage at 18℃ among the dietary treatments (p > 0.05). Furthermore, SPA supplementation did not affect the blood biochemical constituents except for the phosphate content, which was significantly higher in SPA groups than the CON group (p < 0.05). There were no significant differences in visceral organ characteristics and immune indicators (IgA, IgG, and IgM) in SPA or CON groups. Conclusion: This study suggested that the supplementation of SPA may have beneficial effects on feed intake and egg quality in laying hens.
