The effect of Lavandula officinalis nanoemulsion on growth performance, body composition, haematology and immunity parameters of Oncorhynchus mykiss

Effects of lavender essential oil nanoemulsion (LEON) on the growth, body composition, haematology and immunity of Oncorhynchus mykiss was investigated. A total of 276 healthy fishes were distributed into 12 cages to four treatments in triplicate. The fishe were fed a diet consisting of 0, 100, 150...

Summary:Effects of lavender essential oil nanoemulsion (LEON) on the growth, body composition, haematology and immunity of Oncorhynchus mykiss was investigated. A total of 276 healthy fishes were distributed into 12 cages to four treatments in triplicate. The fishe were fed a diet consisting of 0, 100, 150 and 200 ml/kg of LEON for 60 days. Results showed that WG% and SGR (%/day) significantly were increased at the different levels of LEON (p < .05). The highest of WG (%) and SGR were found in 150 ml/kg of LEON (252.16%) followed by 100 and 200 ml/kg. In contrast, FCR was decreased with increasing of dietary supplemental of LEON. The haematology parameters such as RBC, haemoglobin , haematocrit and MCH were significantly increased in 200 ml/kg of LEON compared to the control. ACH50, SOD, lysozyme activity, IgM and total Ig were significantly higher in 200 ml/kg of LEON treatment compared to the control (p < .05). LEON treatments also had a significant influence on body composition like protein and lipid content. Overall, our results interestingly demonstrated that the effect of supplemental dietary LEON especially at the level of 150 and 200 ml/kg had a positive and significant effect on some growth and immunity of rainbow trout.
