Parasitic infections are commonly encountered in livestock reared under traditional animal
husbandry system in India. The parasitic infections especially the helminths infection result in
great economic losses to live stock industry due to deterioration in health and reduced production
of animal. They are treated conventionally with commercially available chemical anthelmentics
which have long been considered as the only effective way of controlling parasitic infection.
Regular use of chemical anthelmintics develops resistance of helminths to various anthelmintics
compounds which is a threat to their use in near future and thus arises a need of development of
alternative approach. Herbal based anthelmintics could be the best possible alternative of these
synthetic anthelmintics, Neem have proven medicinal properties, being anthelmintic, antifungal,
antidiabetic, antibacterial, antiviral, anti-infertility. This article attempts to present some studies
conducted for testing efficacy of Neem as anthelmintic in different livestock species.
