Abstract

This study aims to determine the appropriate egg powder ratio that can be substituted into the fish meal to close the protein deficit withoutadversely affecting the development performance of rainbow trout fry (Oncorhynchus mykiss) (0.38±0.01 g and 3.55±0.05 cm). Also, the effects of eggpowder used as a protein source on rainbow trout feed on growth performance, feed utilization, body composition, and survival rates were investigated. Theegg powder ratio in the ration of the groups were arranged to be 0% (Control), 25% (E-25), 50% (E-50), 75% (E-75), and 100% (E-100) of the amount ofprotein obtained from fish meal. To evaluate their growth performance, fish were fed for 90 days between March and May, and additional feeding was givenfor 17 days for the challenge test. As a result of the study, when the more than 25% egg powder was added to the ration, the final body weight (FBW),weight gain (WG), weight gain rate (WGR), specific growth rate (SGR), feed intake (FI), and protein efficiency ratio (PER) had a statistically significantdifference among the groups (p

Özet

Bu çalışma, gökkuşağı alabalığı (Oncorhynchus mykiss) yavrularının (0.38±0.01 g ve 3.55±0.05 cm) gelişim performansını olumsuz etkilemeden protein açığını kapatmak için balık ununa ikame edilebilecek uygun yumurta tozu oranını belirlemeyi amaçlamaktadır. Ayrıca gökkuşağı alabalığı yemlerinde protein kaynağı olarak kullanılan yumurta tozunun büyüme performansı, yemden yararlanma, vücut kompozisyonu ve yaşama oranları üzerindeki etkileri de araştırılmıştır. Grupların rasyonlarındaki yumurta tozu oranı balık unundan elde edilen protein mikranının %0 (Kontrol), %25 (E-25), %50 (E-50), %75 (E-75) ve %100 (E-100) olacak şekilde hazırlandı. Gelişim permanslarının değerlendirilmesi için Mart - Mayıs ayları arasında 90 gün boyunca beslenen balıklara, challenge testi için ise 17 gün ilave yemleme yapıldı. Çalışmanın sonunda, rasyona %25 den daha fazla yumurta tozu ilavesinin ağırlık kazancı (AA), ağırlık artışı oranı (AAO), spesifik büyüme oranı (SBO), yem alımı (YA) ve protein değerlendirme oranı (PDO) bakımından gruplar arasında farklılaşmaya yol açtığı tespit edildi (p
