Aflatoksin içeren yumurta tavuğu yemlerine sepiolit ve mannanoligosakkarit ilavesinin performans,yumurta kalitesi, kan ve sindirim özelliklerine etkileri
Abstract
Bu araştırmada, ortalama 120 ppb toplam aflatoksin içeren yumurta tavuğu yemlerine sepiolit (% 1.5 ve 3) ve mannanoligosakkarit (MOS, % 0.1) ilavesi yapılmış, bu gruplar, kontrol (K) ve negatif kontrol (NK) grupları ile karşılaştırılmıştır. Deneme tavuklar 26 haftalık yaşta iken başlamış ve 12 hafta devam etmiştir. 5 deneme grubunun her biri 6 tekerrürden ve her tekerrür de rastgele atılan 6 tavuktan oluşmuştur. Gruplar arasında yaşama gücü, canlı ağırlık değişimi, yumurta ağırlığı ve yem tüketimi gibi performans değerleri bakımından önemli farklılıklar gözlenmemiştir (P>0.05). NK grubu, kontrol grubuna göre yemi daha kötü değerlendirmiştir (P<0.05). Yeme % 1.5 düzeyinde sepiolit ilavesi yumurta verimi ve kütlesini NK ve MOS gruplarına göre önemli düzeyde artırmış, yem değerlendirmeyi iyileştirmiştir (P<0.05). Yumurta kalitesini belirleyen özelliklerden kırık-çatlak yumurta oranı, ak yüksekliği, haugh birimi, şekil indeksi, kabuk kalınlığı ve mukavemeti, yumurta sarısı RYCF, L, a ve b renk değerleri bakımından gruplar arasında farklılık bulunmamıştır (P>0.05). Hiçbir grubun yumurtasında aflatoksin tespit edilmemiştir. NK grubundaki tavukların dışkı pH’ının K ve % 3 sepiolit ilaveli gruplara göre yüksek olduğu belirlenmiştir (P<0.05). Dışkı kuru madde oranı bakımından gruplar arasında önemli farklılıklar belirlenmemesine rağmen (P>0.05), NK grubunun diğer gruplardan daha düşük dışkı kuru maddesine sahip olduğu görülmektedir. Yeme MOS ve sepiolit ilaveleri aflatoksinin sindirim derecesini % 612 oranında azaltmıştır. Sonuç olarak, aflatoksin içeren yumurta tavuğu yemlerine sepiolit ilavesinin tavukların performansı üzerine faydalı etkilerinin olabileceği söylenebilir

Effects of dietary sepiolite and mannanoligosaccharide supplementation on the performance, egg quality, blood and digestion characteristics of laying hens receiving aflatoxin in their feed
Abstract
In this experiment, sepiolite (% 1.5 and % 3) and mannanoligosaccharide (MOS, % 0.1) were fed to layers each receiving 120 ppb aflatoxin, and were compared to control (K) and negative control (NK) groups. The experiment began at 26 wk of hen age and continued for 12 wk. Each of the five dietary treatments was randomly assigned to six replicates each included six hens. There were no significant differences (p>0.05) in livability, live weight change, egg weight and feed intake between the groups. NK had worse feed conversion ratio than control (P<0.05). The addition of % 1.5 sepiolite resulted in an increase in egg production and egg mass in comparison to NK and MOS groups, and in an increase in feed efficiency (P<0.05). There were no differences between the groups in parameters characterizing egg quality, namely, in the ratio of cracked-broken eggs, albumen height, haugh unit, shape index, shell thickness, and shell resistance, moreover, in the colour (RYCF), shine (L) and yellowness (b) of egg yolk (P>0.05). Aflatoxin was not detected in eggs obtained from any of the groups. The pH of faeces of hens in the NK group was higher than that of birds in the K and the 3 % sepiolite-treated groups (p<0.05). The proportion of dry matter of the feces was the lowest in the NK group, nevertheless, the difference between the groups was not significant (p>0.05). The addition of MOS and sepiolite to the feed reduced the degree of digestion of aflatoxin by % 6-12. As a result, sepiolite supplementation to laying hen diets containing aflatoxins can be concluded that had the beneficial effects on hen performance
