The Use Of Hazelnut Meal As A Substitute For Soybean Meal In The Diets Of Rainbow Trout (Oncorhynchus Mykiss), Özlem Bi̇lgi̇n, Ali̇ Türker, Ahmet Adem Teki̇nay

Turkish Journal of Veterinary & Animal Sciences

Hazelnut meal as a substitute for soybean meal in extruded feeds of rainbow trout was investigated. The performance of extruded feeds containing hazelnut meal as a substitute for 20% of soybean meal (Diet 2) and 30% of soybean meal (Diet 3) was compared to a nutritionally balanced control (Diet 1) (a commercial trout feed formulation). Each diet was fed to 3 replicate groups (initial BW: 36 ± 1.37 g; mean ± SD); the fish were fed the equivalent of 2% of their body weight, 2 times daily (0800 and 1600) for 64 days at 15 ± 0.11 °C under a …

Pigmentation Of Rainbow Trout (Oncorhynchus Mykiss) With Carotenoids From Marigold Flower (Tagetes Erecta) And Red Pepper (Capsicum Annum), Hakan Murat Büyükçapar, Mahmut Yanar, Yasemen Yanar

Turkish Journal of Veterinary & Animal Sciences

The effects of diets including various natural carotenoid sources and synthetic astaxanthin on the pigmentation and growth of rainbow trout (Oncorhynchus mykiss) were investigated. Rainbow trout weighing about 111 g were fed diets containing 1.6%, 2.4% and 3.2% marigold flower; 4.4%, 6.6% and 8.8% red pepper; 100 mg kg^{-1} synthetic astaxanthin; and a control diet for 60 days. At the end of the experiment, synthetic astaxanthin provided the highest carotenoid accumulation in the fish flesh (6.42 mg kg^{-1}) in the groups. This was followed by red pepper (5.78 mg kg^{-1}) and marigold flower (5.59 mg kg^{-1}), each of which included …
