Özet:

 

In this study, the effects of hazelnut meal (HM) levels in juvenile rainbow trout (Oncorhynchus mykiss) diets on growth,  feed consumption, and digestibility were investigated. Four experimental diets containing a gradient of HM (0%, 15%, 30%  and 45% respectively) were prepared to feed two replicate groups of trout (initial body weight of 37.89±0.02 g) twice daily to  apparent satiation for 60 days. The highest weight gain rate (WGR) and specific growth rate (SGR) were obtained from the  fish fed with Diet 1 and Diet 2 and it was determined that the increase of HM level in the diet up to 30% did not affect feed  conversion ratio (FCR) and protein efficiency ratio (PER). The lowest WGR, SGR and PER were obtained from the fish fed  with the diet containing 45% HM. The apparent digestibility coefficients (ADC) of protein (90.93-91.76%) and lipid (96.78-  98.33%) were at high with no significant difference among treatment (P>0.05). The ADC of dry matter decreased with  increasing HM in diets. These results indicated that HM can be utilized by 15% in diet for juvenil rainbow trout, without  adverse effect on growth performance. 	 	 		 .
