Turba ve Tüy Bazlı Yem Katkı Maddelerinin Adler Gümüş Yumurta Tavuklarında Sindirim ve Üreme Organlarının Gelişimine Etkileri

Öz

Bu çalışmanın amacı turba ve tüy kökenli geleneksel olmayan organik yem katkı maddelerinin Adler gümüşü yumurtacı tavuklarda sindirim ve üreme organlarının gelişimi üzerine etkilerini araştırmaktır. Toplam 180 adet bir günlük yaştaki civcivler, kontrol grubu (temel karma yem) ve iki deneme grubu olacak şekilde üç gruba ayrılmıştır. Araştırma gruplarına sırasıyla turba bazlı katkı maddesi (1 kg/ton) ve tüy bazlı katkı maddesi (2 kg/ton) içeren rasyonlar verilmiştir. Araştırmanın 180. gününde sindirim sistemi ve üreme organlarına ait morfometrik ölçümler yapılmıştır. Araştırma gruplarında, özellikle ince bağırsak ve duodenum uzunluğunda kontrol grubuna kıyasla belirgin artışlar tespit edilmiştir. Ayrıca, ovaryum ağırlığı ve ovidukt uzunluğu deneme gruplarında anlamlı düzeyde artmış olup, bu durum üreme sisteminin daha iyi geliştiğini ve yumurtlama dönemine fizyolojik olarak daha hazır olunduğunu göstermektedir. İncelenen organlarda herhangi bir patolojik değişikliğe rastlanmamış, kullanılan yem katkı maddelerinin hayvan sağlığı ve performans üzerinde olumsuz bir etki oluşturmadığı belirlenmiştir. Sonuç olarak, turba ve tüy bazlı organik yem katkı maddelerinin Adler gümüşü yumurtacı tavuklarda sindirim ve üreme organlarının gelişimini olumlu yönde etkileyebileceği ve kanatlı beslemede alternatif yem katkıları olarak değerlendirilebileceği ortaya konmuştur.

Effects of Peat and Feather-Based Feed Additives on Digestive and Reproductive Organ Development in Adler Silver Laying Hens

Öz

The purpose of this study was to investigate the effects of non-traditional organic feed additives derived from peat and feathers on the development of digestive and reproductive organs in Adler Silver laying hens. A total of 180 one-day-old hens were randomly allocated into three groups: a control group fed a basal compound feed, and two treatment groups receiving the basal diet supplemented with either a peat-based additive (1 kg/ton) or a feather-based additive (2 kg/ton). At 180 days of age, morphometric measurements of the digestive tract and reproductive organs were performed. Hens receiving both feed additives exhibited enhanced development of the digestive system, including increased length of the small intestine and duodenum compared with the control group. Furthermore, supplementation resulted in a significant increase in ovary mass and oviduct length, indicating improved reproductive system development and physiological readiness for egg production. No pathological alterations were observed in the examined organs, suggesting that the additives did not adversely affect the hens’ health status. The findings demonstrated that peat and feather-based organic feed additives can positively influence digestive and reproductive organs development in laying hens, highlighting their potential as alternative components in poultry nutrition strategies.
