Farklı Yem Formundaki Broyler Diyetlerine Bir Bitki Ekstrakt İçeriği Olan Cynarin İlavesinin Kemik Yapı ve Bazı Kan Parametreleri Üzerine Etkisi

Bu çalışmada, diyetlerine bir bitki ekstrakt içeriği olan Cynarin ilavesinin broylerlerde kemik yapı ile bazı kan parametreleri üzerine etkileri ve bu etkide yem formunun rolü incelenmiştir. Araştırmada 480 adet günlük broyler civciv (Ross 308) kullanılmıştır. Her grupta 120 hayvan olacak şekilde 4 eşit gruba ayrılan hayvanlarda çalışma 6 tekrarlı yapılmıştır. Hayvanlara verilen diyetler başlangıç, civciv ve piliç dönemleri için ayrı ayrı hazırlanmıştır. Deneme grupları yem formuna göre iki ana gruba ve her ana grup kendi arasında iki alt gruba ayrılmıştır. Bu gruplar; Toz formu (D1), Pelet Formu (D2), Toz formu+Cynarin (0,25 g/kg yem) (D3) ve Pelet Formu+Cynarin (D4)'dir. Deneme 42 gün sürmüştür. Çalışmada, tibia ağırlığı, kül oranı ile kemik kalsiyum (Ca) ve fosfor (P) içerikleri ile birlikte bazı kan parametreleri değerlendirilmiştir. Deneme grupların ortalama tibia ağırlıklarının yem formuna göre değiştiği saptanmış (P < 0,005) ancak tibia kül oranları ve kemik mineral içerikleri üzerine ise uygulamaların bir etkisinin olmadığı bulunmuştur. Çalışmanın 21. gününde serum üre değerleri üzerine yem formu ve Cynarin arasındaki etkileşimin etkili olduğu saptanmıştır (P < 0,05). Serum trigliserit oranında ise diyete Cynarin ilave edilmesine bağlı olarak bir azalış göstermiş (P < 0,001), diyet formunun da bu azalışta önemli olduğu saptanmıştır (P < 0,03). Araştırmanın 42. gününde ise uygulamaların seçilen kan parametreleri üzerine bir etkisi belirlenememiştir. Denemenin 21. gününde diyete Cynarin ilavesi ile serum fosfor (iP) (P < 0,0001) ve Ca değerlerinin düştüğü (P < 0,006) ve bu düşüşte yemin toz formda olmasının da önemli olduğu saptanmıştır (P < 0,002). Aynı dönemde serum Alkalin fosfataz düzeyi de diyet formuna bağlı olarak değişim göstermiştir (P < 0,036). Çalışmanın 42. gününde Cynarin ilavesinin iP konsantrasyonu üzerine olan olumsuz etkisi devam etmiştir (P < 0,0001). Sonuç olarak, yapılan bu çalışmada yeme Cynarin ilavesinin serum trigliserit oranını düşürücü etkisi saptanmış ve kemik yapısı üzerine yem formunun daha etkin olduğu belirlenmiştir.

treatment arranged factorially with 2 feed form (mash and pellet) and 2 cynarin doses (none, 0.25g/kg). These groups were; mash form (D1), pellet form (D2), mash form+Cynarin (0.25g/kg feed) (D3), and pellet form+Cynarin (D4). The duration o f the trials was 42 days. I n this study, tibia weight, ash rate, tibia Ca and P concentration and some blood parameters were evaluated. The average tibia weight o f the groups differed depending on the form o f the feed (P<0.05), however it was observed that tibia ash ratio and bone mineral content have not changed depending on the diets. On day 21 it was determined that interaction between feed form and cynarin effected on serum urea values (P<0.05). Serum triglyceride value decreased (P<0.001) depending on the Cynarin supplementation in the diets and the form o f the feed had an important role in this effect (P<0.03). On day 42, there were no effects o f applications on selected serum parameters. Cynarin supplementation decreased serum phosphor (iP) (P<0.0001) and calcium (Ca) (P<0.006) values on day 21 and the form o f the feed was also found important i n this changes (P<0.002). During the same period, serum Alkaline phosphatase values also differed depending on the form o f the diet (P<0.036). On day 42, negative effect o f cynarin supplementation on iP concentration continued (P<0.0001). I n conclusion, it was determined that cynarin supplementation decreased serum triglyceride concentration, however, the form o f feed was more effective on the bone structure
