Horozlarda Saf ve Ham Gliserolün Belirlenebilir Metabolize Olabilir Enerji Değeri

Özbilgi/Amaç: Bu çalışma biyodizel yan ürünü olarak açığa çıkan gliserolün horozlardaki belirlenebilir metabolize olabilir enerji AME değerinin tespit edilmesi için düzenlenmiştir. Çalışmada ticari olarak biyodizel üretimi yapan bir tesisten temin edilen bir saf iki ham gliserol örneği incelenmiştir.Materyal ve Metot: Bu amaçla 30 haftalık yaşta 20 adet Hy-line horozu bireysel kafeslerde barındırılmış ve ölçümler öncesinde su ve yeme sınırsız ulaşmalarına izin verilmiştir. Farklı kaynaklardan temin edilen gliserolün AME değerinin belirlenmesi için horozlar 24 saatlik test süresinden önce yine 24 saat süreyle aç bırakılmıştır. Açlık süresinin sonunda 45 g test numunesi bir kanül yardımıyla verilmiştir. Sonrasında dışkı örnekleri örnek toplama poşetleri ile toplanmış ve 60 0C’de kurutularak bomba kalorimetresi yardımıyla ham enerji değerleri belirlenmiştir.Bulgular ve Sonuç: Denemenin sonunda saf ve ham gliserollerin iki ayrı kaynaktan toplanan AME değerleri kuru maddede, sırasıyla 4170, 5587 ve 6763 kkal/kg olarak belirlenmiştir.

Apparent Metabolizable Energy of Pure and Crude Glycerol for Roosters

Backgorund/Aim: An experiment was conducted with roosters to determine the apparent metabolizable energy AME content of glycerol, a co-product of biodiesel production. One pure and two crude glycerol samples which obtain from a commercial biodiesel production facility were investigated in present study.Material and Method: For this aim, twenty of 30 weeks aged Hy-Line roosters were placed in individual metabolic cages and birds had access ad libitum to diet and water before measurements. The determination of AME of glycerol from different sources consisted of a 24 hours preliminary fasting period and a 24 hours excreta period. After the preliminary fasting period, 45 g of testing material was given by funnel. Thereafter gaita samples were collected with help of harness collection bag and all excreta dried at 60 0C and gross energy determined of samples use with bomb calorimeter.Results and Conclusion: At the end of experiment, the AME values for pure and crude glycerine two samples from different sources were 4170, 5587 and 6763 kcal/kg of dry matter, respectively.
