| Abstract | ||
| This study has been carried in the poultry research station of the office agricultural researches/ Ministry of Agriculture from 01/01/2017 to 10/04/2017 to study the Effect of adding different levels of olive leaf powder to diet on productive performance, egg quality characteristics plasma, eggs cholesterol level of quail. In this experiment 800 and quail at the age of 70 days has been used, these birds has randomly distributed on 4 dietary treatments with 4 replicates/ treatment (50 bird/ replicate) Experimental treatments were as follow T1 (Control diet) without supplement, T2, T3 and T4 adding 5, 15, 25 g/ kg olive leaf powder respectively. The results showed significant improvement (P <0.05) in most of the studied productivity traits (egg production rate, cumulative egg count, egg mass, feed consumption rate). For all the treatment to which the olive leafs powder was added compared to the control treatment, the T4 was significantly (P<0.05) the egg weight compared to the control treatment. The results also showed a significant superiority (P <0.05) in the egg quality characteristics of the egg (the diameter height and weight of the yolk, the height of the whiteness and the weight of the crust and (T4) compared to T1 control treatment. The results of this study showed a significant decrease (P<0.05) in the cholesterol concentration of plasma T4 treated blood plasma and did not differ significantly from the other treatments (T2 and T3). Also, the concentration of egg yolk cholesterol (T2, T3 and T4). The addition of olive leaf powder significantly improved (P <0.05) from the oxidation status of egg yolk with a decrease in the concentration of malondiahydride (MDA) in egg yolks T3 and T4, which added olive leaf powder by 15 and 25 g/ kg feed and did not differ (T2) added to the powder by 5 g/ kg feed. We conclude from this study the possibility of adding olive leaf powder in quail diets to improve the production performance and the eggs qualities and reduce the concentration of cholesterol in blood plasma and egg yolks | ||
