摘要

The effects of probiotic Primalac on the growth performance, serum biochemical performance, survival and stress resistance of the Caspian roach (Rutilus rutilus) fry (1.29 ± 0.17 g) was investigated in the present study Four practical diets containing 0 (control), 0.05, 0.1 and 0.15 % probiotic Primalac were used to feed fish. Fish (15 fish/ replicate) were fed on the tested diets at rate of 3 % of body weight for 45 days. Salinity stress test was carried out after 45 days of feeding, in order to determine the effect of Primalac on resistance to salinity stress. Blood samples were obtained in four times after challenge (days 1, 3, 5 and 7) evaluating hematocrit levels. Results showed that final weight, body weight gain and specific growth rate were significantly (P<0.05) increased in treatment groups with Primalac and the highest levels related to fish fed 0.15%. Also, fish fed 0.15 % diet had a significantly highest condition factor compared to the control group and other treatments (P<0.05). Feed conversion ratio was decreased significantly in treatment groups with Primalac (P<0.05). Glucose and cholesterol levels were decreased significantly (P<0.05) in fish fed with diets containing Primalac. In addition, supplementation of Primalac significantly (P<0.05) increased the total protein concentration of probiotic fed groups. On the first day after stress, the hematocrit levels were significantly increased in all groups (P<0.05). The hematocrit levels were decreased in all groups since third day. These results indicate that addition of probiotic Primalac to fish diet exerted positive effects on fish growth and blood biochemical parameters in the Caspian roach.
