Abstract

Ertekin B: Effect of corn distillers dried grains with soluble with or without xylanase supplementation in laying hen diets on performance, egg quality and intestinal viscosity. Kafkas Univ Vet Fak Derg, 24 (2): 273-280, 2018273-280, . DOI: 10.9775/kvfd.2017 Abstract A 14-week experiment was conducted to evaluate the effect of Corn Distillers Dried Grains with soluble (DDGS) with or without xylanase on layers' performance and egg quality traits as well as intestinal viscosity. Four hundred and eighty Atak-S Brown laying hens (32-weekold) were randomly distributed among the eight dietary treatments with six replicates of ten birds each. There was no significant (P>0.05) interaction between DDGS levels and enzyme supplementation for any of the studied parameters (P>0.05). The addition of either 0.0, 10.0, 20.0 or 30.0% DDGS to the diet had no significant (P>0.05) effect on egg production, egg weight, feed intake, feed conversion ratio, body weight gain, livability, eggshell braking strength, eggshell thickness, eggshell ratio, egg albumen height and haugh unit. The addition of any level of DDGS positively affected egg yolk color. On the other hand, 30% of DDGS in the diet caused a significant (P<0.05) decrease in egg mass. The supplementation of enzyme to diets significantly (P<0.05) increased the percentage of egg production. In addition, enzyme supplementation resulted an overall reduction in intestinal viscosity. So, it can be concluded that up to 20% DDGS can be used in laying hen nutrition without adversely affecting any of performance and egg quality parameters, besides xylanase based enzyme supplementation could improve egg production and decrease intestinal viscosity regardless of the inclusion rate of DDGS.

Çalışma 32 haftalık yaşta 480 adet ATAK-S kahverengi yumurtacı tavuk kullanılarak 6 tekerrürlü ve her bir alt grupta 10 adet tavuk olmak üzere 8 grupta tesadüf parselleri deneme düzeninde yürütülmüştür. Araştırma sonucunda yumurta tavuğu yemlerinde DDGS kullanım seviyeleri ile ksilanaz enzimi ilavesi arasında araştırmada incelenen performans yumurta kalitesi ve incebağırsak viskozitesi parametrelerinin hiçbirinde önemli bir interaksiyon tespit edilmemiştir (P>0.05). Ayrıca yemlerde farklı oranlarda DDGS bulunmasının yumurta verimi, yem tüketimi, yem değerlendirme sayısı, yumurta ağırlığı, yaşama gücü, canlı ağırlık yanında yumurta kabuk kırılma direnci, kabuk kalınlığı, kabuk oranı, albumen yüksekliği ve haugh birimi gibi yumurta kalite kriterleri üzerine de önemli bir olumsuz etkisi bulunmamışken (P>0.05), DDGS varlığı yumurta s...

“…Similarly, xylanase (EC 3.2.1.8) is responsible for degradation of linear polysaccharide β-1,4-xylan into xylose. These fiber degrading enzymes (cellulases and xylanases) have attracted much interest due to their vast applications in food, animal feed, textiles, fuel, chemical and pharmaceutical industry [4,5] . The global market for these enzymes was valued at 899.19 million dollars in 2014 and is projected to reach 1371.03 million dollars by 2020, at an annual growth rate of 7.3% from 2015 to 2020.…”
