Etlik piliç yemlerine esansiyel yağ karışımı ilavesinin büyüme performansı, karkas randımanı ve bazı iç organ ağırlıkları üzerine etkileri

Yeme esansiyel yağ karışımı (EYK) ilavesinin etlik piliçlerin büyüme performansı, karkas randımanı ve bazı iç organ ağırlıkları üzerine etkilerini belirlemek amacıyla 2 deneme yürütülmüştür. Her bir denemenin hayvan materyalini günlük yaşta ve karışık cinsiyette 400 adet etlik civciv oluşturmuştur. Her iki denemede de piliçlerin yarısına temel yem karması verilirken, diğer yarısına ise altı farklı esansiyel yağın karışımından oluşmuş EYK ilave edilmiş yem verilmiştir. Yeme EYK ilavesinin birinci denemede etlik piliçlerin büyüme performansı üzerine istatistiki olarak herhangi bir etkisi olmazken (P>0.05), ikinci denemede hem üç hem de altıncı hafta canlı ağırlıklarını artırmış ve yemden yararlanmayı iyileştirmiştir (P0.05). Yem EYK ilavesi birinci denemede karkas randımanını artırmıştır (P

The effect of dietary essential oil mixture supplementation on the broiler performance, carcass yield and some ınternal organ weight

Two experiments were conducted to evaluate the effects of dietary essential oil mixture supplementation (EOM) on the performance, carcass yield and some organ weights of broilers. A total of 400 one-day-old broiler chicks (Ross-308) per one experiment were randomly assigned to 2 groups. Half of the broilers were given untreated basal diets while the remaining birds were fed on the basal diet supplemented with EOM containing a blend of six essential oils. Dietary EOM supplementation did not promote growth in the experiment 1 (P>0.05), while EOM increased body weight and improved feed conversion ratio between 0-3 and 0-6 weeks in the experiment 2 (P<0.01). Feed intake and mortality was not affected by EOM supplementation in both trials (P>0.05). Supplementation diet with EOM increased carcass yield in the experiment 1 (P<0.05). In addition, pancreas weight was increased in response to EOM in the second trial. Overall results showed that an EOM can be used as performance enhancer in broiler diets.
