Kurutulmuş damıtma çözünürlü tanelerinin kanatlı beslenmesinde kullanımı

Kurutulmuş damıtma çözünürlü taneleri (KDÇT) etanol üretiminde mısır ve çeşitli farklı tahılların fermantasyonu sonucu yan ürün olarak elde edilen bir yem maddesidir. Fermantasyon sırasında birbirine yakın düzeylerde etanol, karbondioksit ve KDÇT elde edilmektedir. Etanol üretiminin gün geçtikçe artması, yaygınlaşması ve bu alanda yeni etanol bitkilerin kullanılması üretilen KDÇT'lerin miktar ve kalitesinin artmasını kaçınılmaz hale getirmiştir. KDÇT'ler diğer hayvanların rasyonlarmda değerlendirilebildiği gibi kanatlı hayvanların rasyonlarmda da alternatif bir yem hammaddesi olarak değerlendirilebilmektedir. Kanatlı rasyonlarında KDÇT kullanılırken, bu ürünlerin kalitesinin, besin maddesi kompozisyonunun ve sindirilebilirliğinin göz önünde bulundurulması gerekmektedir. KDÇT'nin kanatlılarda kullanımı üzerine yapılan çalışmalarda rasyonlara katılma oranlarının sınırlı düzeyde olduğu görülmektedir. Yayınlanan son makaleler göz önünde bulundurularak hazırlanan bu derlemenin amacı, kanatlı ve yem sektörü ilgililerine KDÇT'lerin üretimi, yem değeri, yem değerini etkileyen faktörler ve kanatlı beslemede kullanımı konularında bilgi vermektir.

Use Distillers dried grains plus solubkes in poultry diets

Abstract: Distillers dried grains with solubles (DDGS) is a feed material, which is obtained from fermentation of corn and different cereals as a by-product in the process of ethanol production. During fermantation, approximately equal portions of ethanol, DDGS and CO2 are obtained. The increase in ethanol production, becoming widespread and using new generation ethanol plants, increases the amount and the quality of the produced DDGS. The DDGS from new generation plants can be evaluated an alternative ingredient for poultry as well as other animal rations. Quality, nutrient composition and nutrient digestibility of products should be considered when DDGS are used in poultry rations. The supplemention levels of DDGS have been seen to be limited in experiments conducted in poultry. The aim of this review prepared by considering the latest articles published is to inform poultry sector and feed mill industry about the subjects of DDGS production, its feed value and factors that effect its feed value.
