Abstract :This study was aimed to determine effects of the addition of dry spinach leaves to laying hen diets on performance, egg quality and yolk colour. A total of 40 Lohman white laying hens, 38 weeks old, were allocated to 4 treatment groups, with 10 replicates in individual cages. The treatment groups were as follows: 1); Negative control group insert ignore into journalissuearticles values(NC, there is no colorant);, 2); Positive control group insert ignore into journalissuearticles values(PC, there is commercial colorant); in basal diet);, 3); 1% ground dry spinach leaf addition to the diet insert ignore into journalissuearticles values(SL1); and 3); 2% ground dry spinach leaf addition to the diet insert ignore into journalissuearticles values(SL2);. Supplementation of dried spinach leaf to the laying hen diet did not affect live weight, feed consumption, hen-day egg production, feed conversion ratio insert ignore into journalissuearticles values(FCR);, shape index, and shell thickness. However, the highest egg weight was found in the NC group, and the lowest in the PC and SL2 groups insert ignore into journalissuearticles values(P<0.01);. The SP1 group`s egg mas was higher than the other groups, and SP` group`s egg mas was lower than the other groups insert ignore into journalissuearticles values(P<0.05);. The albumen height was higher in the NC than the SL2 group insert ignore into journalissuearticles values(P<0.01); and similar PC and SP1 groups. In the NC and PC groups, Haugh unit values were higher than SL2 groups insert ignore into journalissuearticles values(P<0.05);. Egg yolk lightness insert ignore into journalissuearticles values(L*); in the NC group was higher than SP1 and Sp2 supplemented groups and SL` group`s yellowness insert ignore into journalissuearticles values(b*); and redness insert ignore into journalissuearticles values(a*); were higher than other groups insert ignore into journalissuearticles values(P<0.01);. In the PC group yolk color fan value was lower than those of other groups insert ignore into journalissuearticles values(P<0.01);. In conclusion, the use of 1% dry spinach leaves addition to laying hen diets may sufficient to increase the egg yolk color without negatively affecting the performance and egg quality.
