Black cumin (Nigella sativa) is a widely used medicinal herb found worldwide. It is native to Southern Europe, North Africa and Southwest Asia and it is cultivated in many countries in the world like Middle Eastern Mediterranean region, South Europe, India, Pakistan, Syria, Turkey, Saudi Arabia. Black cumin seeds contain a fatty oil rich in unsaturated fatty acids, mainly linoleic acid (50-60%), oleic acid (20%), eicodadienoic acid (3%) and dihomolinoleic acid (10%). Specific applications studied in poultry include:
Egg Quality: Black cumin at the level of 2 or 3% positively influenced egg production, egg weight, and shell quality and decreased the concentration of cholesterol in the egg yolk.
Antibacterial: Adding 2% black cumin seeds to the diet of laying hens can decrease Escherichia coli counts.
Antiviral: Black cumin extract can inhibit Infectious Bronchitis virus at an early point in infection, probably by rendering the virus non-infectious.
