Abstract
Bu araştırmanın amacı; damızlık yumurtacı tavuk rasyonlarına (Lohmann LB) bitkisel kaynaklı 1.25- dihidroksikolekalsiferol (1.25(OH)2D3) katılmasının, yumurta kabuk kalitesi ve çıkım sonuçları üzerindeki etkilerini belirlemekti. Araştırma; 38 haftalık yaşta 20000 damızlık yumurtacı (Lohmann LB) tavuğun bakıldığı Hastavuk A.Ş.’ye ait damızlık kümesinde yürütüldü. Araştırmada kullanılan rasyonlar yine Hastavuk A.Ş.’ye ait yem fabrikasında toz formda hazırlandı. Araştırma süresince (38-48. haftalar); kontrol grubundaki hayvanlar standart damızlık yumurtacı tavuk rasyonu ile beslenirken, deneme grubunun rasyonuna kontrol grubundan farklı olarak 10 ppm dozda bitkisel kaynaklı 1.25(OH)2D3 katıldı. 1.25(OH)2D3 katkılı rasyonu tüketen deneme grubunun yumurta kabuk kalınlığında 40 (P<0.05) ve 48. (P<0.01) haftalarda, yumurta kabuk kırılma direncinde ise 42. haftada (P<0.05) istatistik düzeyde bir iyileşme saptandı. Ancak araştırma süresince yapılan ölçümler total olarak değerlendirildiğinde (38-48. haftalar), kontrol ve deneme grubunun kabuk kalitesi ve kuluçka sonuçları arasında oluşan farklılıkların istatistik açıdan önem taşımadığı tespit edildi. Sonuç olarak; Vitanin D’nin aktif formu olan 1.25(OH)2D3’ün, vitamin D metabolizmasında aksaklıkların yaşandığı yaşlı hayvanların rasyonlarına katılması durumunda etkili olabileceği kanısına varıldı.
The aim of this study was to determine effects of herbal 1.25-dihydroxycholecalciferol (1.25(OH)2D3) supplementation on the eggshell quality and hatching results in layer breeders. The experiment was performed at breeding hen house containing 20000 layer breeders (38 weeks old) which belongs to joint-stock company Hastavuk. The diets used in experiment also were prepared at the same company. During experiment (38th - 48th weeks), layer breeders in control group were fed with standart layer breeder diets, while treatment group were fed diet containing 10 ppm of herbal 1.25(OH)2D3 differently from control group. A significant improvement was determined in eggshell quality at 40th (P<0.05) and 48th (P<0.01) weeks and in eggshell breaking strength at 42nd (P<0.05) week in treatment group supplemented fed with 1.25(OH)2D3. However, when the measurements performed during experiment were evaluated totally (38th - 48 th weeks), there was no significiant difference between control and treatment group in eggshell quality and hatching results. It was concluded that the supplementation of 1.25(OH)2D3 (active form of vitamin D) to the diets of old layer breeders who has an irregular Vitamin D metabolism may be effective.
