Zusammenfassung: | This study was performed to evaluate the effects of adding different levels of natural zeolite (clinoptilolite) to juvenile rainbow trout (Onchorynchus mykiss) diets about growth performance and some biochemical blood parameters. The experimental system was designed as a semi-recirculating aquaculture system and 20 rainbow trouts which weigh 7.91±0.03 g distributed randomly for each tank (300 L). Fish were fed to apparent satiation with diets containing 45% crude protein and 14% crude fat for 70 days which included no zeolite (Control), 0.5% zeolite (Z05), 1% zeolite (Z1), 2.5% zeolite (Z25) in triplicate. Finally, blood samples were collected from all fish tanks to analyze some biochemical blood parameters like cholesterol, triglycerides, LDL, HDL, and VLDL. At the end of the experiment, Z25 group showed negative results in final body weight, weight gain, and specific growth rate (p0.05) compared to the control group. As a result, there was a tendency towards decreased growth and feed utilization due to the addition of zeolite higher than 1% in diets. It could be concluded that limited usage of clinoptilolite in rainbow trout diets might have beneficial effects on growth parameters.
Bu çalışma, genç gökkuşağı alabalığı (Onchorynchus mykiss) diyetlerine farklı seviyelerde doğal zeolit (klinoptilolit) eklenmesinin büyüme performansı ve bazı biyokimyasal kan parametreleri üzerindeki etkilerini değerlendirmek amacıyla yapılmıştır. Deney sistemi, yarı devridaim yapan bir kültür balıkçılığı sistemi olarak tasarlanmış ve her bir tanka (300 L) 7.91±0.03 g ağırlığında 20 gökkuşağı alabalığı rastgele dağıtılmıştır. tasarlanmıştır. Balıklar, %45 ham protein ve %14 ham yağ kompozisyonlu zeolit içermeyen (Kontrol),% 0.5 zeolit (Z05),% 1 zeolit (Z1),% 2.5 zeolit (Z25) içeren diyetlerle 70 gün boyunca doyana kadar beslenmiştir. Son olarak, kolesterol, trigliseritler, LDL, HDL ve VLDL gibi bazı biyokimyasal kan parametrelerini analiz etmek için tüm balık tanklarından kan örnekleri alınmıştır. Deney sonunda Z25 grubu son vücut ağırlığı, ağırlık artışı ve spesifik büyüme oranında negatif sonuçlar göstermiştir (p |
