Abstract

This experiment was conducted to investigate the effects of ginger extract on production performance and egg quality of laying hens. A total of 600 Hy-Line brown laying hens aged of twenty-five-week-old were randomly divided into 2 groups with 4 replicates per group and 75 laying hens per replicate. Hens in the control group were fed a basal diet, and others in the experimental group were fed basal diet supplemented with 0.1% ginger extract. The adaptation period lasted for 1 week, and the formal period lasted for 7 weeks. The results showed as follows:1) compared with the control group, during 1 to 4 weeks of the experiment, the production performance indexes of laying hens in experimental group had no significant difference (P>0.05); during 5 to 7 weeks of the experiment, the laying rate of laying hens in experimental group was significantly increased (P<0.01), the ratio of feed to egg and deformed eggs ratio were significantly decreased (P<0.05). 2) Compared with the control group, the laying rate of laying hens in experimental group at the 5th, 6th and 7th week was significantly increased (P<0.05 or P<0.01). 3) Compared with the control group, the egg shape index of laying hens in experimental group was significantly increased (P<0.01), the eggshell weight and eggshell thickness were significantly increased (P<0.05). In conclusion, dietary supplemented with 0.1% ginger extract can improve the production performance of laying hens, and also has beneficial effect on egg quality of laying hens.
