Aim:
The aim of the study was to evaluate the effect of two doses of ashwagandha on physiological parameters and reproductive parameters in Awassi sheep in Iraq.

Methods:
Thirty Awassi ewes were randomly assigned to three groups (10 each): a control (placebo), 300 mg/day ashwagandha, and 600 mg/day ashwagandha, for 60 days. Physiological (hepcidin, growth hormone, insulin, TSH, T3, T4) and reproductive (estrogen, progesterone, FSH, LH) parameters were measured on days 0, 30, and 60, while body weights were recorded weekly.

Results:
The experimental data demonstrated that both experimental groups showed increased growth hormone levels along with decreased hepcidin and Insulin levels, thyroid hormone levels (T3 and T4) increased significantly (P
