This experiment was conducted to study the effects of Bacillus subtilis on immune function and disease resistance of immunized and unimmunized Huanghe carp (Cyprinus carpio Huanghe var.). A total of 1 920 Huanghe carp with an average initial body weight of (35.36±0.46) g were randomly divided into 8 groups (groups Ⅰ to Ⅷ) with 3 replicates per group and 80 fish per replicate. The groups Ⅰ to Ⅳ were immunized groups which were injected antigen, and the groups Ⅴ to Ⅷ were control groups which were injected stroke-physiological saline solution. The supplemental levels of Bacillus subtilis in the experimental diets were 0 (groups Ⅰ and Ⅴ), 1.5×1011 (groups Ⅱ and Ⅵ), 3.0×1011 (groups Ⅲ and Ⅶ) and 4.5×1011 CFU/kg (groups Ⅳ and Ⅷ), respectively. The experimental fish were fed the experimental diets for 28 days, and subsequently fed the basal diet for 28 days. The leukocytes phagocytic activity, serum lysozyme activity and serum antibody titer were determined on the 7th, 14th, 21st, 28th, 35th and 42nd day after immunization. The experimental fish were challenged by Aeromonas hydrophila on the 42nd day after immunization, and the mortality of each group was counted for the calculation of immune protection rate. The results showed as follows: Bacillus subtilis supplementation could significantly improve the leukocytes phagocytic percentage and phagocytic index, and serum lysozyme activity of immunized and unimmunized Huanghe carp (P<0.05). The serum antibody titer of Huanghe carp in group Ⅲ was the highest, which was 486.7; the second was group Ⅳ, which was 372.6; the third was group Ⅱ, which was 234.6; the last one was group Ⅰ, which was 192.8. The Huanghe carp in immunized groups all had a certain immune protection rate, and the supplementation of 4.5×1011 CFU/kg Bacillus subtils induced the highest immune protection rate of immunized Huanghe carp. It is concluded that the supplementation of Bacillus subtilis can improve the immune function and disease resistance of immunized and unimmunized Huanghe carp, and the supplemental level of Bacillus subtilis in diets is suggested to be 3.0×1011 to 4.5×1011 CFU/kg.
