The Relationship of Adding Allicin Powder to Diet on Concentration of Glutathione Enzyme and Histological of Thymus Gland of Broiler
Keywords:Allicin, glutathione, thymus gland, broiler.
This study was conducted at the field of poultry - Abu Gharib/department of Animal Production/college of
agricultural engineering Sciences - university of Baghdad, during the period from 12/10/2019 to 24/11/2019
duration (42 days), to demonstrate the effect of adding different levels of Allicin to broiler diet on Glutathione
level in blood and histological of thymus gland, total of 225 Ross 308 chicks was used. Birds were randomly
distributed into five treatment groups which were : First treatment T1: without additives to diet (control),
other treatments T2, T3, T4, T5 was added Allicin at a rate of (800,600,400,200 mg/Kg diet) respectively,
and Allicin was added from first day until the end of the experiment for all addition treatments, results of this
experiment showed: High significant (P<0.01) in all additive treatments compared to control for glutathione
enzyme in plasma at 21, 42 days for broiler age. With respect to the histological examination of thymus
gland showed that adrenocortical hyper function and degeneration and depletion in lymphoid tissue in T2,
T3 and T5 treatments compared to control treatment, while cortex and Pulp with a lymphatic interstitial in
the stage of degeneration for T4 and control treatments.
