Farklı Düzeylerde Enerji ve Protein İçeren Yemlerle Beslenen Broyler Civciv ve Piliçlerin Bazı Verim Özellikleri

Bu araştırmada farklı düzeylerde enerji ve protein içeren yemlerin broyler civciv ve piliçlerin canlı ağırlık artışları, yem tüketimleri, yemden yararlanma dereceleri, abdominal yağ birikimleri ve yem maliyetleri üzerine etkileri incelenmiştir.Farklı düzeylerde protein ve enerji içeren rasyonları tüketen grupların canlı ağırlıkları arasında önemli bir farklılık gözlenmemiştir (P>0.05). Yem tüketimleri ve yemden yararlanma dereceleri bakımından da gruplar arasında önemli bir farklılık bulunmamıştır. Enerji düzeyi yüksek yemleri tüketen grupların abdominal yağ miktarları diğerlerinden önemli ölçüde yüksek bulunmuş (P<0.05) ve en düşük abdominal yağ miktarı 0-28. günlerde 3001 Kcal/kg enerji ve °/o22.9 HP; 28-49. günler arasında 3111 Kcal/kg enerji ve %20.12 HP içeren yemleri tüketen 4. gruptan elde edilmiştir. Bir kg karkas maliyeti bakımından da 4. grup diğerlerinden daha avantajlı bulunmuştur.

Some Yield Characteristics of Broilers Consumed Rations Containing Different Levels of Energy and Protein.

In this study, the effect of the feeds with different levels of energy and protein on live weight gain, feed intake, feed efficiency ratio, abdominal fat deposition and feed cost of broiler chicks and chickens were investigated. No significant differences had been observed between groups consumed different levels of protein and energy in diet (P<0.05). Also, no differences for feed efficiency ratio were found betıveen groups. Abdominal fat deposition were found significant for groups consuming diet with high level energy (P<0.05).The lowest abdominal fat deposition had been obtained in diets with 3001 Kcal/kg energy and 22.9 °/o CP in the 0-28 th days; ıvith 3111 Kcal/kg energy and 20.12 °/o CP in 25-49 th days the fourth group. Based on the cost of 1 kg carcass, the fourth group has been found to be more advantageous.
