     The purpose of this experiment was to investigate the effect of different levels of the Lavandula angustifolia extract on semen quality of broiler chickens during storage in a liquid condition at 4°C. Semen was collected from 10 Ross-308 broiler breeder roosters twice a week for 4 weeks, and immediately mixed together after the initial evaluation. The semen samples were divided into 5 parts after dilution and each received 0, 5, 10, 15 and 20 µg/ml levels of Lavandula angustifolia extract. Semen quality parameters were evaluated at 0, 3, 6, 12, 24 and 48 hours after storage at 4°C. Adding different levels of Lavandula angustifolia extract resulted significant increase in total and progressive sperm motility after 6 hours of semen storage (P<0.05). The effect of Lavandula angustifolia extract on sperm survival rate was significant (P<0.05). So that treatment with 10 μg/ml of this extract at 12, 24 and 48 hours improved this parameter compared to control (P<0.05). Adding 10 μg/ml of Lavandula angustifolia extract to seminal fluid resulted significant increase in plasma membrane integrity of the sperm after 48 hours of semen storage (P<0.05). 24 and 48 hours after semen storage in liquid condition, the least amount of sperm abnormalities belonged to treatments of 10 and 15 μg/ml extract and the highest amount was in the control and high dose extract (P<0.05). In general, the addition of Lavandula angustifolia extract at 10 μg/ml to diluted semen of broiler roosters improved sperm parameters during semen storage at 4°C.
