Abstract
This study aimed to determine the effects of adding myrtus (Myrtus communis L.) leaf oil and vitex (Vitex agnus-castus) oil in laying hen diet on performance parameters such as live weight, egg production, feed intake, feed efficiency and the internal and the external of egg quality. In the study, a total of 80 white laying hens aged 30 weeks, assigned to 4 groups with 10 replicates. Control group was fed with basal diet. The treatment groups were fed with the diets supplemented 2 ml/kg of myrtus leaf oil, 2 ml/kg of vitex oil and 1 ml/kg of myrtus leaf oil + 1 ml/kg of vitex oil were added to treatment groups feed respectively. In the study, 28.61% of α-pinene and 46.32% of 1.8-cineole were identified in myrtus leaf oil and 13.22% of α-pinene, 14.03% of sabinene and 26.14% of 1.8-cineole were identified as significant active compounds of vitex oil. Supplementation of myrtus leaf oil and vitex oil alone and mix to laying hens diet did not affect body weight, feed intake, egg production and feed efficiency. Egg specific gravity was decreased significantly in group including vitex oil (P<0.05). Haugh unit, egg shell thickness, yolk index and albumen index were not affected by the volatile (P>0.05). Egg yolk color decreased by mix supplementation of myrtus leaf oil and vitex oil to diet (P≤0.001), but no change was determined by supplementation of these oils as alone (P>0.05). Consequently, it was determined that supplementation as alone or mix of myrtus and vitex volatile oil to the laying hen diet did not affect production performance and internal and external quality of the egg, except for egg specific gravity and yolk color during the peak egg production period.
Özet
Bu çalışma, yumurtacı tavuk yemlerine mersin yaprağı (Myrtus communis L.) uçucu yağı (MUY) ve hayıt (Vitex agnus-castus) uçucu yağı (HUY) ilavesinin canlı ağırlık, yumurta verimi, yem tüketimi, yemden yararlanma gibi performans parametreleri ile yumurta iç ve dış kalitesine etkisini belirlemek amacı ile yapıldı. Çalışmada, 30 haftalık yaşta, 80 adet beyaz genotipte yumurta tavuğu, 10 tekrarlı 4 gruba ayrıldı. Kontrol grubu bazal yemle, deneme grupları ise sırasıyla 2 ml/kg MUY, 2 ml/kg HUY ve 1 ml/kg MUY + 1 ml/kg HUY ilave edilen yemlerle beslendiler. Çalışmada kullanılan MUY’nın önemli bileşeni olarak %28,61 α-pinene ve %46,32 1,8-cineole; HUY’ın önemli bileşeni olarak %13,22 α-pinene, %14,03 sabinene ve %26,14 1,8-cineole belirlendi. Yumurtacı tavuk yemlerine HUY ve MUY’nın tek başına ya da birlikte kullanılması canlı ağırlık, yem tüketimi, yumurta verimi, yumurta ağırlığı ve yemden yararlanmayı istatistik yönden etkilemediği belirlendi (P>0,05). Yumurta özgül ağırlığı HUY içeren gruplarda istatistik açıdan önemli oranda azaldı (P<0,05). Haugh birimi, kabuk kalınlığı, sarı ve ak indeksi ise muamelelerden istatistik yönden etkilenmedi (P>0,05). Yumurta sarı rengi ise MUY ve HUY’nın birlikte kullanımında azaldı (P≤0,001), fakat ayrı kullanımında ise değişmediği belirlendi (P>0,05). Sonuç olarak, yumurtacı tavukların pik yumurta verim döneminde yeme MUY veya HUY’nın tek başına veya birlikte ilavesinin yumurta özgül ağırlığı ve sarı rengi dışındaki parametrelere önemli bir etkisinin olmadığı belirlendi.
