Özet
Bu çalışma tercihli yemlenen yumurta tavuklarında protein- mineral konsantresi, buğday ve enzim kullanımının yumurta verim ve kalite parametreleri üzerinde etkilerini incelemek amacıyla yapılmıştır. Denemede Ankara Tavukçuluk Enstitüsü tarafından geliştirilen 90 adet 23 haftalık yaşta Atak-S yumurtacı hibritler kullanılmıştır. Muamele grupları, standart bir yumurtacı yeminden oluşan kontrol, yüksek proteinli düşük enerjili bir konsantre yem ve iri öğütülmüş buğdayın ayrı yemliklerde tercihli olarak verileceği KB grubu ve tercihli olarak sunulan buğdaya 3.000 FTU/kg fitaz, 1.720.000 VU/kg 1-3 ?-glukanaz ve 2.500.000 VU/kg 1-4 ?- ksilanaz içeren bir enzim ilave edilmiş KBE gruplarından oluşmak üzere, 2 tekerrürlü 3 muamele grubundan oluşturulmuştur. Deneme sonucunda yumurta verimi, tercihli yemlemede buğday kullanılmasından etkilenirken ve yumurta ağırlığı tercihli yemlemeden etkilenmiştir (P<0,01). Tavuk başına tüketilen yem miktarı da tercihli yemlemede buğday kullanılmasından etkilenmiştir (P<0,05). Tercihli yemlemede buğday kullanımı bu unsurlarda azalmaya neden olurken, enzim kullanımı KB grubuna göre daha iyi sonuçlara neden olmuştur. Yem dönüşüm oranları tüm gruplarda istatiksel olarak etkilenmemiştir (P>0,05). Albumin ağırlığı, kabuk ağırlığı ve kabuk kalınlığı tercihli yemlemede buğday kullanılmasından etkilenmiş olup enzim kullanımının bu kriterler üzerinde iyileştirici bir etkisi vardır (P<0,05). Yumurta sarı renginde ise tüm gruplar arasındaki fark istatiksel olarak önemli bulunmuştur (P<0,01). Albumin yüzdesi, albumin indeksi, Haugh birimi, yumurta kabuk yüzdesi, kırılma direnci, sarı yüzdesi, sarı ağırlığı, sarı- ak oranı, sarı indeksi ve şekil indeksi gibi kalite parametrelerinde tüm gruplar arasında istatiksel bir fark saptanmamıştır (P>0,05). Son olarak bir yumurtanın üretim maliyeti ve net kar, kontrol ile KB grubunda benzer değerler iken enzim kullanılan grupta maliyet oldukça azaldığından kar yükselmiştir.
This study was carried out to examine the effects of protein-mineral concentrate, wheat and enzyme usage on egg yield and quality parameters in choise-feeding laying hens. In the experiment, 90 Atak-S layer hybrids at the age of 23 weeks, developed by Ankara Poultry Institute, were used. Treatment groups consisted of a standard layer feed control, a high protein low-energy concentrate, and the KB group where coarsely ground wheat will be given choise in separate feeders, and it was formed from 3 treatment groups with 2 replications, consisting of KBE groups added with an enzyme containing 3.000 FTU/kg phytase, 1.720.000 VU/kg 1-3 ?-glucanase and 2.500.000 VU/kg 1-4 ? xylanase to wheat, which is optionally offered . As a result of the experiment, egg production was affected by using wheat in choise-feeding and egg weight was affected by choise-feeding (P<0,01). The amount of feed consumed per chicken was also affected by the use of wheat in choice-feeding (P<0,05). While the use of wheat in choice-feeding caused a decrease in these factors, the use of enzymes led to better results compared to the KB group. Feed conversion rates were not statistically affected in all groups (P>0,05). Albumin weight, eggshell weight and eggshell thickness were affected by the use of wheat in choice-feeding, and the use of enzymes had a curative effect on these criteria (P<0,05). The difference in egg yolk color between all groups was statistically significant (P<0,01). There was no statistical difference between all groups in quality parameters such as albumin percentage, albumin index, haugh unit, eggshell percentage, breakage strength, yolk percentage, yolk weight, yolk-white ratio, yolk index and shape index (P>0,05). Finally, while the production cost and net profit of an egg were similar values in the control and KB group, the profit increased in the enzyme group as the cost decreased considerably.
