Abstract
This study was conducted in the field quail of the Agriculture College/University of Basrah for the period from 24/11/2018 to 04/01/2019 to study the effect of adding different levels of dietary Marjoram (Origanumvulgarae) and (Rosmarinus officinalisL) on some productive of Japanese Quail in the study (450) chick. Unsexed one day old chicks were used at an initial weight 8.5 g. The chicks were randomly distributed into Ten treatments each treatment contained 45 chicks with three replicates each one has 15 chicks, the treatments as the following T1,T2,T3,T4,T5,T6,T7,T8,T9,T10 (Control, Adding 5 g powder of marjoram leaves from one day to 21 days, Add 5 g of marjoram powder from the age of 22 to 42 days, Adding 5 g of rosemary leaves powder from 1 day to 21 days, Adding 5 g of rosemary leaves from 22 to 42 days, Adding 2.5 g powdered leaves of marjoram and 2.5 g of rosemary leaves from 1 day to 21 days, Adding 2.5 g powdered leaves of marjoram and 2.5 g of rosemary leaves from 22 to 42 days, Adding 5 g of powder of marjoram leaves from one day to the end of the experiment, Adding 5 g of rosemary leaves powder from one day to the end of the experiment, Adding 2.5 g powder of marjoram leaves and 2.5 g of rosemary leaves from one day to the end of the experiment. There was a significant (p ≤ 0.05) increase in the final body weight and cumulative weight gained, and a significant (p ≤ 0.05) improvement in the cumulative feed conversion ratio compared with control treatment, while no significant (p ≤ 0.05) differences were found in the amount of feed intake.
