Özet
Bu arastırmada etlik piliç yemlerinin hazırlanmasında yaygın olarak kullanılan bitkisel kaynaklı bir yag olan soya yagı ile bitkisel kaynaklı olmasına ragmen fiziksel özellikleri sebebiyle hayvansal yag özellikleri gösteren palm yagının farklı yetistirme dönemlerinde soya yagı yerine kullanılmasının etlik piliçlerin performans ve karkas parametrelerine etkileri arastırılmıstır. Deneme için 3 farklı yetistirme dönemi (baslatma yemi: 1. - 14. günler, büyütme yemi: 15. - 28. günler, bitirme yemi: 29.- 42. günler) ve 2 farklı yag ilavesi (soya yagı ve palm yagı) olmak üzere 6 farklı yem, mısır, tam yaglı soya ve soya fasulyesi küspesi agırlıklı ve yetistirme dönemleri için izonitrojenik ve izokalorik olarak hazırlanmıstır. Uygulanan 4 muamele ise su sekildedir; 1) Tüm yetistirme dönemlerinde soya yagı, 2) Baslatma ve büyütme dönemlerinde soya yagı, bitirme döneminde palm yagı, 3) Baslatma döneminde soya yagı, büyütme ve bitirme dönemlerinde palm yagı, 4) Tüm yetistirme dönemlerinde palm yagı, ilaveli yemler ile yemleme yapılmıstır. Denemenin sonuçlandırıldıgı 42. gün her bir deneme ünitesinden birer hayvan servikal dislokasyon ile öldürülerek, duodenum, jejunum, ileum, abdominal yag, karaciger, dalak, taslık, ön mide, pankreas ve kalp kısımları ayrılarak tüm kısımlar ayrı ayrı tartılarak kayıt edilmis. Her bir kısmın agırlıgının canlı agırlıga bölünmesi ile organ agırlıklarının canlı agırlıga oranı hesaplanmıstır. Daha sonra karkas; gögüs, butlar, kanatlar ve boyun kısımları olarak 4 parçaya ayrılmıs ve tüm parçalar ayrı ayrı tartılarak kayıt edilmis ve her bir karkas parçası grubunun agırlıgının karkas agırlıgına bölünmesi ile karkas parçalarının karkasa oranı hesaplanmıstır. Çalısmanın sonuçları performans parametreleri açısından incelendiginde etlik piliç yemlerinde doymus yag oranı yüksek olan palm yagının kullanımının yetistiriciligin erken dönemlerinde tercih edilmemesi, bu dönemde soya yagı gibi doymamıs yag oranı yüksek olan bitkisel yagların kullanılmasının daha olumlu sonuçlar verdigini göstermektedir. Büyütme ve bitirme yemlerinde ise maliyeti soya yagına göre daha düsük olan palm yagının kullanılması istatistiksel açıdan önemli bir fark olusturmamıstır. Ayrıca karkas parametreleri açısından da olumsuz bir etkinin olmadıgı bulunmustur.
This experiment was carrier out to study the effects of palm oil addition instead of soybean oil on the performance and skeleton parameters during different period of growth where soybean oil is a vegetable oil but palm oil has animal fat specifications although it broiler is vegetable oil, either in this study sex is sorted. For the tests three growth periods are determined such as starter diet: 1st – 14th days, grower diet 15th – 28th days, finisher diet 29th – 42nd days; and 2 different oil additives and 6 different feeding mixtures are prepared predominantly using, corn, full fat soybean and soybean beans meal and prepared in isonitrogenic and isocaloric for all growth periods. The treatments are shown below; 1) Soybean oil is used in all growth periods, 2) Soybean oil additives in feeds are used in starter and grower diets and palm oil additives in feeds is used in finisher diets, 3) Soybean oil additives in feeds are used in starter diet and palm oil additives in feeds is used in grower and finisher diets, 4) Palm oil additives in feeds are used in all periods. The experiment was lasted in 42 days. At the end of the experiment one bird was killed from each cervical dislocation unit and organs duodenum, jejunum, ileum, abdominal fat, liver, spleen, gizzard, proventriculus, pancreas and hearts of them were removed and weighted separately and recorded and standardized according to 100 g body weight as well. Then carcasses were gathered in 4 parts as breast, leg, wing and neck all parts were separately weighted and recorded and each carcass parts were divided to carcass weight to determine the ratio of carcass parts to carcass weight. The results of the present experiment show that palm oil, which is rich in saturated fatty acid ratio, shouldn’t be preferred at the early periods of growth and using soybean oil which is rich in unsaturated fat ratio, gives better results. In grower and finisher periods using palm oil which is comparatively cheaper than soybean oil, hasn’t shown a distinct difference statistically. In conclusion, it is determined that usages of palm oil do not have any negative effect with respect to carcass parameters.
