Abstract :
In this study, the effect of mistletoe extract added to rainbow trout diet was investigated on growth indicators, blood factors and blood serum biochemistry of rainbow trout. For this purpose, fish with an average weight of 11.3 ± 1.28 grams were fed with salmon basic food (40% protein and 16% fat) with different levels of zero (control), 0.5, 1 and 1.5% of mistletoe extract for 45 days. At the end of the feeding period, blood was drawn from the caudal vein of fish. Growth indicators, blood (white and red blood cell count, hemoglobin and hematocrit, MCV, MCH and MCHC and differential count of white blood cells), blood serum biochemistry (protein, glucose, albumin, cholesterol, triglyceride), metabolic enzymes including alkaline phosphatase enzyme ( ALP), alanine aminotransferase (ALT), lactate dehydrogenase (LDH) and aspartate aminotransferase (AST) were measured. The obtained results showed that in all the growth and nutrition indicators, the total number of red blood cells, blood hemoglobin, albumin, cholesterol, triglyceride, glucose and ALT, AST and LDH enzymes in the serum of fish fed with a diet containing mistletoe extract was significantly different from the treatment. There is a witness. The results of this study show that the addition of mistletoe extract to the diet of rainbow trout has a positive effect on improving the growth indicators, blood and biochemical variables of the fish.
