Abstract

In this experiment, the effect of barberry root powder and methanol extract on the growth and immunohematological parameters of rainbow trout (Oncorhynchus mykiss) was studied. A total of 306 rainbow trout fingerlings (15.55  0.76g) were fed for 8weeks with six experimental diets: control (C), BRP10 (10gkg−1 of barberry root powder), BRP20 (20gkg−1 of barberry root powder), BRE250 (250mgkg−1 of barberry root extract), BRE500 (500mgkg−1 of barberry root extract), and oxytetracycline OTC30 (30gkg−1). The results indicated BRE250, BRE500, and OTC30 had significantly higher weight gain (93.04, 92.52, and 90.48g, respectively) compared with other dietary treatments (P < 0.05). The highest levels of WBC (26.5  103), RBC (1.8  106), HB (9.47gdl−1), MCHC (22.19gdl−1), lymphocytes (67.67%), lysozyme (65.67), and ACH50 (139) in fish fed BRE500 diet were observed (P < 0.05). Also, inhibition zone appeared with the barberry against Aeromonas hydrophila in vitro. Totally, it is suggested that the BRE500 diet can be used as a natural stimulant of growth and immunity in the aquaculture industry.
