The present study was performed to examine the effects of probiotic addition to diet containing soybean meal (SBM) on growth and intestinal histomorphometry of rainbow trout. A total of 300 fry with mean initial weight of 20.05 ± 0.20 g were distributed to 12 tanks for 90 days. Experimental diets were included control (SBM 0 + probiotic 0), SBM 0 + probiotic 1, SBM 20% + probiotic 0, SBM 20% + probiotic 1, SBM 40% + probiotic 0 and SBM 40% + probiotic 1. On the 30th day, the highest body weight increasing rate (BWI %) and specific growth rate (SGR) were observed in diet containing SBM 0 (0 and probiotic 1) and SBM 20% + probiotic. On the 60th day, adding probiotic to SBM 0 and SBM 20% led to the highest BWI (p < 0.05). The lowest values of final weight, BWI (%) and SGR were achieved in SBM 40% without probiotic (p |
