Abstract
The experiment was carried out in the poultry field of the Department
of Animal Production/College of Agriculture/the University of Diyala during the
period from 4/9/2021 to 15/10/2021 to study the effect of adding ginkgo leaf extract to broiler diets as an antioxidant and study its impact on the productive performance of birds. This experiment used 225 unsexed hybrid broiler chicks (age:
one day). The average weight of the chick was (43.62 g.). Firstly, The chicks
were randomly distributed by using five experimental treatments. Each treatment
has three replicates (15 birds/repeat). Experimental transactions are as follows.
T1 = (control treatment) A standard diet without addition is provided, T2 =
standard ratio to which 1 g/kg of Ginkgo Biloba leaf extract is added, T3 =
Standard diet to which 2 g/kg of Ginkgo Biloba leaf extract is added, T4 = a
standard diet to which 3 g/kg of Ginkgo Biloba leaf extract is added, and T5 =
standard ration to which 4 g/kg of Ginkgo Biloba leaf extract is added. The results of the experiment were as follows. The experiment results indicated a significant effect (P≤0.05) when adding different levels of Ginkgo biloba leaf extract to the diets of 308 Ross broilers for 1-42 days. The fourth treatment was superior to the average live body weight during the sixth week and the cumulative
weight gain compared to the control. There is a significant superiority (P≤0.05) in
the rate of cumulative feed consumption, cumulative feed conversion, efficiency
and production index value, where all the addition treatments (1,2,3,4)g/kg feed
excelled compared to the control.
