Effect of dietary supplementation of peppermint and eucalyptus essential oils on serum biochemical parameters of Japanese quails

Abstract

This experiment was carried out to study the effect of dietary supplementation of peppermint and eucalyptus essential oils on the serum biochemical parameters of Japanese quails. A total of 180 Japanese quail chicks were divided into 5 groups with 3 replicates containing 12 birds each. The treatments were as follows: T0 (basal diet), T1 (basal diet + 0.2% peppermint essential oil), T2 (basal diet + 0.2% eucalyptus essential oil), T3 (basal diet + 0.1% each of peppermint and eucalyptus) and T4 (basal diet + 0.05% each of peppermint and eucalyptus). After 35th day of rearing, blood samples were collected from 2 birds of each replicate. It was analysed and the serum biochemical parameters were determined. The results revealed that serum glucose, serum total cholesterol, serum triglycerides, serum LDL cholesterol, serum uric acid, serum creatinine, serum bilirubin concentration, SGPT and SGOT activity was reduced significantly (p
