Changes in Blood Parameters and Some Biochemical Factors of Rainbow Trout (Oncorhynchus mykiss) Fed with Different Levels of Ginger Extract Zingiber officinale

In the past few years, the use of safe stimuli of vegetable origin has increased in aquaculture. Ginger is one of the medicinal plants that has been used in aquaculture in a number of studies. Ginger has attracted much attention due to its important effects on growth and health

In the present study, changes in hematological and some blood and biochemical parameters of rainbow trout with mean weight of 45.80±3.60 g by adding 0, 1, 3, 6 and 10 g / kg ginger extract in the diet for 8 weeks were evaluated.

The results showed that the use of ginger extract in the diet of rats, white blood cells, hematocrit and lymphocytes in the 10 g / kg treatment had a significant difference with the control group (P <0.05), while hemoglobin, MCV, MCH, MCHC, neutrophil counts and monocytes showed no significant difference (P> 0.05). Total protein, total albumin, and total globulin also showed a significant difference with the control group (P <0.05), but glucose, cholesterol and triglyceride did not significantly (P> 0.05).

The results of the present study showed that the use of ginger extract in the diet changes some blood and biochemical parameters of rainbow trout blood and improves the health of rainbow trout.
