Özet
In this study was evaluated the effects of rosemary (Rosmarinus officinalis)essential oil on performance and eggshell quality parameters of laying hens. Inexperiment, a total of 192 twenty four-week-old NOVOgen White laying henswere assigned to the basal control diet supplemented with 50, 100, 150, 200and 250 mg/kg of rosemary essential oil (6 treatment diets, 8 replicates, eachreplicate consists of 4 hens). Hens were fed with experimental diets from 24 to36 weeks of age. Water and feed were supplied ad libitum throughout theexperiment. The results of study indicated that there were no differences in eggproduction, feed intake, feed conversion ratio, egg weight, egg mass as performance parameters among the treatment groups. The eggshell weight had nosignificantly affected by the dietary treatments. However, eggshell thicknessand eggshell breaking strength were significantly affected by the treatments(P< 0.05). The eggshell thickness was significantly increased fed with 250mg/kg rosemary essential oil supplemented of group when compared to thecontrol group. The breaking strength was increased by the addition of dietaryrosemary essential oil. The results of this study demonstrated that performanceparameters were not significantly influenced with rosemary oil addition inlaying hens diet. But, rosemary oil addition in laying hens diet significantlyincreased to eggshell breaking strength. It may be said that the dietary additionof 50 mg/kg of rosemary essential oil would be beneficial to improve the eggshell quality in laying hens.
