RASYONDA FARKLI SEVİYELERDE AZALTILAN VİTAMİN-MİNERAL PREMİKSİNİN YUMURTLAYAN BILDIRCINLARDA PERFORMANS, YUMURTA KALİTESİ VE KAN PARAMETRELERİNE ETKİSİ

Öz

Bu çalışmanın amacı yumurtlayan bıldırcın rasyonlarında azaltılmış vitamin ve iz mineral premiksinin performans, yumurta kalitesi ve kan parametreleri üzerine etkisini belirlemektir. Sekiz haftalık yaştaki toplam 100 adet bıldırcın her birinde 5 bıldırcının bulunduğu 4 tekerrürlü 5 muamele grubuna rastgele dağıtılmıştır. Bıldırcınlar tavsiye edilen miktarın %0 (kontrol), 25, 50, 75 veya 100 seviyesinde vitamin ve iz mineral premiksinin azaltılması ile oluşan beş deneme rasyonu ile 10 hafta boyunca yemlenmişlerdir.

Muamelelerin canlı ağırlık değişimi, yumurta ağırlığı ve kitlesi, yemden yararlanma oranı, şekil indeksi, kabuk kırılma direnci ve MCH ve MCHC hariç kan parametreleri üzerine etkisi olmamıştır (P>0.05). Yumurta verimi ve yem tüketimi vitamin ve iz mineral premiksinin katılmadığı grupta önemli derecede düşük olmuştur (P<0.01). Haugh birimi ve ak indeksi rasyonda vitamin ve iz mineral premiks seviyesinin azalmasıyla düşmüştür (P<0.01).  Diyette vitamin ve iz mineral premiksinin %50 azaltılması kabuk ağırlığını (P<0.05) ve kalınlığını (P<0.01) olumsuz etkilemiştir. Kan MCH ve MCHC değerleri diyette azalan vitamin ve iz mineral premiksi seviyesi ile artmıştır.

Sonuç olarak yumurtlayan bıldırcın rasyonlarına vitamin ve iz mineral premiksinin tavsiye edilen miktarda ilavesinin performansın ve yumurta kalitesinin devamlılığı için gerekli olduğu söylenebilir.

The Effect of Reduced Vitamin-Mineral Premix at Different Levels in Diet on Performance, Egg Quality and Blood Parameters in Laying Quails

Öz

The aim of this study was to determine the effect of reduced vitamin and trace mineral premix on performance, egg quality and blood parameters in laying quail diets. A total of 100 quails, 8 weeks old, were randomly distributed into 5 treatment groups with 4 replicates pens of 5 birds. The quails were fed for 10 weeks on a five-trial diet consisting of a reduction of vitamin and trace mineral premix of 0 (control), 25, 50, 75 or 100% of the recommended amount. 

Treatment had no effect on body weight change, egg weight and mass, feed conversion ratio, egg shape index, egg breaking strength or blood serum parameters except MCH and MCHC (P>0.05). Egg production and feed intake were significantly lowered in the group without vitamins and trace minerals premix (P<0.01). Haugh unit and white blood index decreased with reduced vitamin and trace mineral premix levels in the diet. Reduction of 50% of vitamin and trace mineral premix in the diet adversely affected eggshell weight (P<0.05) and thickness (P<0.01). Blood MCH and MCHC values increased with decreased vitamin and trace mineral premix levels in the diet.

As a result, it can be said that the recommended amounts addition of vitamins and trace mineral premixes to the layer quail diets is necessary for maintaining performance and egg quality.
