Abstract

This study was designed to investigate the effects of dietary lavender oil supplementation on productive performance and health, including growth, mortality, and blood biochemical parameters of quails. A total of 90 one-day-old, unsexed quail chicks were obtained from the local market of Mosul, Iraq, weighed, and randomly distributed into three experimental groups, each with 30 chicks in three replicates (15 chicks per each). Groups comprised a control group (0 % lavender oil) and two experimental groups fed diets supplemented with 0. 2 and 0.4 % lavender oil, respectively. The results showed a notable increase (P<0.05) in body weight, body weight gain, and feed intake of birds fed a diet containing lavender oil. The best feed conversion ratios were recorded in lavender oil supplemented groups (0.2 and 0.4%). A notable elevation (P≤0.05) in triglyceride and cholesterol levels was seen in quail administered lavender oil diets (0.2% LO and 0.4% LO) relative to the control group. The number of deaths was significantly lower (P≤0.05) in the groups that received lavender oil (0.2% LO and 0.4% LO) compared to the control group during the entire study. In
conclusion, adding lavender oil improved the production characteristics and some
physiological characteristics of quails, so we recommend adding lavender oil to quail or
broiler feed.
