Abstract (2. Language): 
The aim of this research was to investigated the effects of different fat sources (soybean oil (SO), canola oil (CO), acid oil (AO) and calcium-palm fatty acid (Ca-PFA)) on broiler carcass yield, small intestine length, abdominal and gizzard fat content and composition of meat fatty acid. In the experiment, 240 day-old Ross-308 broiler chicks were used. The chicks were randomly allocated into four dietary treatments with six replicate pens per treatment (5 female and 5 male in each cage). All experimental diets were formulated to contain the same level of metabolisable energy and crude protein. The results showed that carcass ratio of CO groups were detected highest value than the other group (P<0.001). Supplemental fat sources changed meat fatty acid content especially miristic (P<0.001), palmitic (P<0.001), oleic (P<0.001), linoleic (P<0.001) and linolenic acid (P<0.05). When the addition of the Ca-PFA in the broiler diets small intestine length was the longer than other groups (P<0.001). On the other hand, carcass parts yield and abdominal and gizzard fat did not show differences among the groups. However, the female broilers had more abdominal fat and meat oleic acid than the males (P<0.05).

Abstract (Original Language): 
Bu araştırma, farklı yağ kaynaklarının (soya yağı, kanola yağı, asit yağ ve palm yağ asitlerinin kalsiyum tuzu) etlik piliçlerde karkas oranı, ince bağırsak uzunluğu, abdominal yağ ve taşlık yağ miktarı ile ette yağ asitleri profili üzerine etkilerinin belirlenmesi amacıyla planlanmıştır. Denemede günlük yaşta 240 adet Ross 308 civciv kullanılmıştır. Civcivler 4 grupta 6 tekerrürlü ve her tekerrürde 10 civciv (5 dişi ve 5 erkek) olacak şekilde gruplara rastgele dağıtılmışlardır. Araştırmada kullanılan rasyonlar enerji ve protein bakımından birbirine benzer şekilde düzenlenmiştir. Deneme sonunda en yüksek karkas randımanı kanola yağı tüketen gruplarda tespit edilmiştir (P<0.001). Rasyona katılan yağ kaynakları etin özellikle miristik (P<0.001), palmitik (P<0.001), oleik (P<0.001), linoleik (P<0.001) ve linolenik asit (P<0.05) miktarlarını değiştirmiştir. Palm yağ asitlerinin kalsiyum tuzu ile beslenen etlik piliçlerde ince bağırsak uzunluğu diğer gruplara göre daha yüksek bulunmuştur (P<0.001). Diğer taraftan karkas parça oranları ile abdominal ve taşlık yağ oranları gruplarda birbirine benzer gerçekleşmiştir. Dişi hayvanların erkeklere göre daha fazla abdominal yağ ile ette oleik asit miktarına sahip olduğu tespit edilmiştir (P<0.05).
