“…This is in agreement with previous studies aimed at investigating the effects of different dietary nutrients on body composition in broilers (Fraps 1943;Donaldson et al 1956;Kubena et al 1972;Edwards et al 1973).…”

“…Therefore, birds that were fed 3,400 kcal and 3,600 kcal ME.kg -1 had higher (p<0.05) energy intake when compared to those receiving 3,200 kcal ME.kg -1 . According to Matterson et al (1955) and Donaldson et al (1956), birds will reduce feed intake proportionally after the energy requirements have been achieved. In this experiment it may be inferred that energy requirements in broilers older than 44 weeks of age may be higher than 3,200 kcal ME.kg -1 , since a decrease in feed intake was not seen when diets with 3,400 and 3,600 ME.kg -1 were administered.…”

An experiment was conducted to evaluate the performance and carcass yield of broilers at 55 days of age fed diets with different levels of metabolizable energy and lysine. Evaluated data of performance were weight gain, feed intake, energy intake, lysine intake, caloric conversion and feed conversion. Carcass assessment was performed based on data from carcass yield, breast weight, whole wings, whole legs, back, head + neck, feet and abdominal fat. A 3 x 3 factorial arrangement was used, with 3 levels of metabolizable energy (3,200; 3,400 and 3,600 kcal ME/kg) and 3 lysine levels (0.95%; 1.05% and 1.15%). There was no interaction between the two factors. Nevertheless, increasing levels of metabolizable energy improved weight gain (745 g; 841 g and 910 g, respectively) and feed intake was higher in broilers receiving the diets with 3,200 and 3,600 kcal ME/kg. Overall performance was not affected by lysine levels. Feed conversion values were 2.69, 2.42 and 2.14 for birds fed diets with 3,200; 3,400 and 3,600 kcal ME/kg, respectively. Carcass yield and breast weight increased with higher levels of energy and lysine in the diets.

“…Dört haftalığa kadar civcivlerin beslenmelerinde rasyondaki prodüktif enerji yoğunluğunun büyüme hızı, yem tüketimi ve vücut yapısı bakımıarından rasyon proteinini önemli derecede etkilediği belirtilmiştir (9). Rasyonda Produktif Enerji-Protein oranının geniş-letilmesinin her ünite canlıağırlık artışı için tüketilen protein miktarını düşürdüğü ve buna karşılık enerji tüketimini yükselttiği açıklanmıştır (9, ro).…”
