Effects of Chitosan Oligosaccharides Addition to Japanese Quail's Diets on Growth, Carcass Traits, Liver and Intestinal Histology, and Intestinal Microflora

Bu çalışma, bıldırcın rasyonlarına farklı oranlarda kitosan oligosakkarit (KOS) ilavesinin besi performansı, karkas verim özellikleri, karaciğer ve barsak histoloj isi ile barsak mikroflorası üzerine etkilerini belirlemek amacıyla yapıldı. Araştırmada 240 adet Japon bıldırcını kullanıldı. Civcivler herbiri dört alt gruptan oluşan üç ana gruba ayrıldı, Kontrol grubu temel başlangıç (1-21. gün) ve büyütme (22-42. gün) yemleriyle beslendi. Deneme grupları araştırma süresince bu yemlere 75 mg/kg (Deneme I) veya 150 mg/kg (Deneme II) KOS ilave edilerek beslendi. Araştırma sonu itibariyle Kontrol ve Deneme I grubunun canlı ağırlığı Deneme IIden önemli derecede yüksek bulundu. Canlı ağırlık artışı, yem tüketimi, yemden yararlanma oranı ve karkas verim özellikleri bakımından gruplar arasında farklılık görülmedi. Deneme II grubundaki bıldırcınların karaciğerindeki yağlanmanın Kontrol ve Deneme Iden daha az olduğu gözlendi. Kript derinliği ve villus uzunluğu Deneme II grubunda diğer gruplardan önemli derecede yüksek bulundu. İnce barsaklardaki bakteri ve maya sayıları Deneme I ve II gruplarında Kontrol grubundan daha düşük bulundu. Sonuç olarak, bıldırcın rasyonlarına 75 mg/kg kitosan oligosakkarit ilavesinin incelenen parametreler üzerinde olumsuz bir etki oluşturmadığı, kript derinliğini ve villus yüksekliğini artırdığı, ince barsak mikroflorası üzerinde faydalı olduğu tespit edilmiştir.

Bıldırcın Rasyonlarına Kitosan Oligosakkarit İlavesinin Besi Performansı, Karkas Özellikleri, Karaciğer ve Barsak Histolojisi ile Barsak Mikroflorası Üzerine Etkisi

This research was conducted to determine effects of chitosan oligosaccharides (COS) addition to quail diets on growth, carcass traits, liver and intestinal histology, and intestinal microflora. Two hundred forty Japanese quail chicks were distributed among three treatments groups, with four replicates. A group was fed with a basal starter diet for 1-21th and a grower diet for 22-42th days (Control). The experimental groups were fed the same diets, in addition to 75 mg/kg (Trial I) or 150 mg/kg (Trial II) of COS. The final live weights of the quails in the Control and Trial I groups were higher than in the Trial II group. There were no differences among the groups in gain, feed intake, feed conversion, and carcass traits. Steatosis in the Trial II group was less than in the Control and Trial I groups. Crypt depth and villus length were higher in the Trial II group than in the other groups. The number of bacteria and yeast in the intestine were lower in the Trial I and II groups than in the Control group. In conclusion, the addition of 75 mg/ kg of COS had no adverse effect on the tested parameters, and it increased the crypt depth, villus length, and beneficially on intestinal microflora.
