Özet
ÖZET Arpa buğday ve Endofeed adlı pentozanaz ve B-glukanaz aküvitli enzimin etlik piliçlerde canlı performans ve karkas öğelerine etkisini ölçmek üzere bir deneme düzenlenmiştir. Bu amaçla bir günlük Cobb broyler etlik piliçler alınmış 14 gün süreyle standart broyler başlatma yemiyle yemlendikten sonra deneme yemleri yedirilmiştir. Arpa, buğday, arpa + enzim ve buğday + enzime dayalı test yemleri fomüle edilmiş ve broyler başlatma, büyütme ve bitirme yemleri olarak sırasıyla 7, 14 ve 7 gün süreyle 14 günlük civcivlere yedirilmiştir. Buğday ve arpaya dayalı yemlere p - glukanaz ve pentozanaz aktivitesi içeren, Endofeed 500 g/ton düzeyinde ilave edilmiştir. 4 muameleden oluşan test yemleri 6'şar tekerrür halinde herbirinde 10'ar civciv bulunan 3 katlı kafes ünitelerine şansa bağlı olarak tahsis edilmiştir. Bu amaçla toplam 240 civciv kullanılmış olup deneme süresince (14-42. günler arasında) test yemleri ile adlibitum olarak yenilenmiştir. Civcivlere nipel suluklarla su verilmiş denemenin yürütüldüğü oda 24 saat süreyle aydınlatılmıştır. Arpa, buğday ve Endofeed enziminin broyler canlı performansına etkilerini ölçmek üzere civcivler haftalık olarak tartılmış, yem tüketimleri saptanmış, canlı ağırlık artışı ve buna bağlı yem dönüşüm oranlan ölçülmüştür. Muamelelerin karkas kalitesi ve öğelerine etkilerini ölçmek üzere denemenin sonunda (42. gün) her tekerrürden 1 erkek ve 1 dişi şansa bağlı olarak seçilip ölçüm yapmak üzere kesilmiştir. Daha sonra karkas randımanı, abdominal yağ, but, göğüs, kanat oranları saptanmıştır.Bu çalışmanın sonucunda arpa+enzim grubunun diğer gruplara göre canlı ağırlık artışı ve yem dönüşüm oranı bakımından istatistiksel olarak (P<0.05) önemli derecede iyi olduğu ortaya çıkmıştır. Canlı ağırlık değerleri buğday, buğday + enzim, arpa, arpa + enzim olan gruplarda sırasıyla 1723, 1677, 1779, 1958 g olmuştur. Yem dönüşüm oranları ise bu muamelelere göre sırasıyla 1.973, 1.957, 1.898, 1.845 çıkmıştır. Karkas randımanı, abdominal yağ ve karkas öğeleri bakımından arpa, buğday ve enzim kullanımının istatiksel olarak önemli bir etkisi olmamıştır. Arpa ile P-glukanaz aktiviyesi içeren Endofeed enziminin etlik piliç yemlerinde canlı performans ve ve karkas kalitesini olumsuz yönde etkilemeksizin % 60-75 oranlarında broyler yemlerinde kullanılabileceği sonucuna ulaşılmıştır.

m SUMMARY An experiment was conducted to examine the effects of enzyme addition to wheat or barley based diets upon live performance and carcass yield and carcass parts. Day old Cobb broiler male and female mixed chicks were given standart broiler starter for the first 14 days. Wheat, wheat + enzyme, barley, barley + enzyme based test broiler diets were formulated as starter, grower and finisher and fed to 14 day old chicks for 7, 14 and 7 days respectively. Endofeed (with p- glucanase and pentozanase activity, was added to barley and wheat based diets at 500 g/ton dose level. The 4 treatments were randomnely assigned at 6 replication in three tier broiler wire cages in which chicks 10 were housed. 240 fourteen days old chicks were housed in cage units and fed ad libitum with test diets from 14 to 42 days of age. Birds were accesed to nipple drinkers freely. Experimental house were illuminated for 24 hours. To test the effects of enzyme supplementation to wheat or barley based diets the birds were weighed weekly, feed consumtions and feed conversion values were measured. To examine the effects of the treatments upon carcass quality two birds (one male and one female) from each replication were randomely selected and killed by cervical dislocation araştırmada the end of the experiment (42. Day). Then, carcass yield, abdominal fat, legs, breast and wings ratios were measured as parts of the carcass. The results of this experiment demonstrated that broiler group fed with Endofeed supplemented barley based diet was significantly highes in body weight and lower in feed conversion companed to other treatments (P<0.05). The body weight values of wheat, wheat+enzyme, barley, barley + enzyme were 1723, 1677, 1779, 1958 g respectively and the respective values of according to the treatmentsIV were 1.973, 1.957, 1.898, 1.845. Dietary treatments did not significantly effect carcass yield or carcass parts. It was concluded that endofeed (an enzyme preparation with P-glucanaz activity) supplemented barley can be used up to % 60-75 in broiler diets without any negative effects upon live performance and carcass quality. Key words: Barley, wheat, p - glucanaz, broiler, performance, carcass quality.
