The aim of this study was to evaluate the hematological parameters in Cyprinus carpio juvenile feeding of Basilli sp. probiotics in the condition of before and after long distance transports.
In this experimental research, 180 carp juvenile were stocked in 2 tanks (capacity 400-L) for 45 days. Fish juvenile in one tank was feeding with multi-strain probiotic (Protexin) were used at a concentration of 1×107 CFU/ liter and fish in the other tank was not consumed probiotic. At the end of the feeding trial, the carp juvenile from both treatments randomly were packed in plastic bags (40-L) at the density of 1kg/bag (~20 fish/bag). The juvenile feeding previously from probiotic were packed in 2 treatments with/or without of NaCl in water. Also, the juvenile feed of the control tank was packed in bags as the control. The bags unpacked after 12h and blood samples were taken from 10 fish in each replicate and hematological parameters were compared among the groups.
Results indicate that WBC, Hematocrit, Hemoglobin, MCV, MCH, MCHC and leukocytes differential count are affected by after transport stress and before the catching (p<0.05). However, there were no significant differences in the amounts of RBC and hemoglobin in experimental treatments (p>0.05).
Based on the results, finding of this study indicated that feeding of common carp juvenile with Basilli sp. probiotics had positive effects on blood parameters after long-distance transportation in plastic baggage, thereby if used in diet, it can be good alternatives to salt.
