Özet
This study was performed to examine the effect of differentconcentrations of an essential oil mixture (EOM) added to drinking water on growth performance, internal and external eggquality, and egg yolk fatty acid composition in laying hens. Atotal of 240 Brown Nick laying hens aged 20 weeks were usedin this study. These hens were divided into one control and three treatment groups whose drinking water was supplementedwith 0, 0.1, 0.2, and 0.3 ml/L of Oregofarm EOM. Oregofarm isa commercially available product containing peppermint, oregano, and anise oil. Each treatment group was further categorized into 10 subgroups, each consisting of 6 laying hens. Thehens were fed basal rations for 16 weeks. For data collectionand analysis, a 16-week period was divided into three time periods of 5 weeks. The weights of 25- to 30- and 35-week eggswere recorded weekly. In the groups whose drinking water wassupplemented with the EOM, there was a significant improvement in egg production (EP) (p<0.001), weekly egg weightsduring the entire study period (p<0.001), and feed conversionratio (p<0.05). Furthermore, egg shell thickness and yolk heightwere significantly increased (p<0.05) at week 35. The Haughunit was also significantly improved (p<0.05) at weeks 25 and30. However, feed intake and body weight were not affected bythe treatment (p>0.05). The levels of saturated fatty acids weredecreased, whereas the levels of polyunsaturated fatty acidsincreased with EOM supplementation, although the differences were not statistically significant (p>0.05). Therefore, basedon the beneficial effects of supplementing drinking water withdifferent concentrations of EOM on egg weight, egg production, feed conversion ratio, and egg yolk fatty acid compositions,it is suggested that EOM can be safely added at concentrationsof up to 0.3 ml/L (i.e., the levels used in this study) to drinkingwater for laying hens.
