Abstract
The present study was conducted to evaluate the effect of dietary supplementation of essential oil on growth performance, nutrient utilization of japanese quail birds. A total of two hundred (200), a day-old Japanese quail chicks were taken and divided randomly into five different treatment groups (T1, T 2, T3, T4 and T5) and every group was having four replicates having ten chicks in each. Diets were prepared by addition of cinnamon and peppermint essential oils in different concentrations, treatment group T1-basal or control diet for 35 days, T2-basal diet supplemented with cinnamon essential oil @500 ppm, T3-basal diet supplemented with peppermint essential oil @500 ppm, T4-basal diet supplemented with combination of cinnamon and peppermint essential oil @250 ppm each, T5 -Basal diet supplemented with combination of cinnamon and peppermint essential oil @ 500 ppm each. Gut histological parameters were found to be improved in all essential oil supplemented groups. Villus height (μm) was found higher (p<0.05) in essential oil supplemented groups than control. Crypt depth (μm) was found higher (p<0.05) in T2 and T3 group than control. It was concluded that dietary supplementation of cinnamon oil (@500ppm), peppermint oil (@500ppm) and combination of cinnamon and peppermint oil (@250 ppm each) significantly (p<0.05) improved gut morphological parameters, without adversely affecting blood biochemical parameters in Japanese quail birds.
