Özet
Bu çalışmada bor, zeolit ve bor-zeolit karışımı içeren yemlerin yaşlı yumurtacı tavuklar üzerine etkileri incelenmiştir. Araştırma 65 haftalık yaşta 576 adet beyaz yumurtacı tavukla (Süper Nick) 15 hafta süresince yürütülmüştür. Çalışmada kontrol grubu (1. Grup) katkısız yemi tüketirken, 2. grup 100 mg/kg bor ilaveli yemi, 3. grup 8 g/kg zeolit ilaveli yemi, 4. grup ise 100 mg/kg bor ve 8 g/kg zeolit ilaveli yemi tüketmişlerdir. Yeme bor ve zeolit ilavesinin yumurta verimi üzerine etkisi istatistiksel olarak önemsizken (P>0.05), yumurta ağırlığı (P<0.01) ve miktarını (P<0.05) azaltmıştır. Gruplar arasında yem tüketimi ve yemden yararlanma oranı arasındaki fark istatistiksel olarak önemsiz bulunmuştur. Yeme bor-zeolit ilave edilen grupta yumurta kalite (iç-dış kalite) özelliklerinden kabuk kalınlığı önemli düzeyde artarken (P<0.01), muamelelerin diğer tüm özellikler üzerine etkisi istatistiksel olarak önemsiz bulunmuştur. Yeme bor ilavesi, serum bor yoğunluğunu arttırmış (P<0.01), kalsiyum (Ca) ve fosfor (P) miktarını istatistiksel olarak değiştirmemiştir. Yem muamelesiyle gübre Ca, P ve bor (B) düzeyleri etkilenmiştir (P<0.01). Zeolit ve B içerikli yemler, tibia Ca (P<0.05) ve B (P<0.01) yoğunluğunu arttırmıştır. Yeme bor ve zeolit uygulaması yumurta kabuğu kül içeriğini arttırmış (P<0.01), fakat kabuktaki Ca, P ve B içeriğini istatistiksel olarak etkilememiştir.
The effects of feeds containing boron and zeolite, either alone or in combination, on aged laying hens was assessed in the study. A total 576 laying hens of commercial white strain (Super Nick), 65 wk of age, were used in this experiment which was lasted for 15 weeks. Experimental feeding groups were as follows: basal diet without boron and zeolite (control), basal diet with added boron (100 mg/kg diet), basal diet with zeolite (8 g/kg diet) and basal diet with combination of boron (B) and zeolite (100 mg/kg boron + 8 g/kg zeolite), respectively. B and zeolite, either alone or combination, reduced egg weight (P<0.01) and egg mass output (P<0.05), but did not influence statistically egg yield. The differences in the feed intake and feed conversion ratio among the groups were not statistically significant. While egg shell thickness in egg quality (internal and external quality) characteristics increased in the boron-zeolit group (P<0.01), the effect of treatment on the other egg quality properties were not statistically significant. Dietary treatments with added boron increased (P<0.01) serum concentrations of B, whereas had no effect on serum calcium (Ca) and phosphorus (P) levels. Fecal excretion of Ca, P and B were affected by dietary modifications (P<0.01). The diets with zeolite and B increased Ca level (P<0.05) and B (P<0.01) concentrations in tibia. All of the supplemental regimens increased ash content of the eggshell (P<0.01), but did not affect statistically mineralization of Ca, P and B in eggshell.
