The potential of Nigerian bioactive plants for controlling gastrointestinal nematode infection in livestock

Bioactive compounds from marine and terrestrial organisms have been used extensively in the treatment of many diseases in both their natural form and as templates for synthetic modifications. This review summarizes present knowledge about anthelmintic effects of the extracts of bioactive plants in Nigeria against helminth parasites of ruminants. Plants traditionally used in livestock production are discussed. The main focus is hinged on in vitro and in vivo activities of secondary plant metabolites against nematodes of livestock. This review provides insight into preliminary studies of medicinal plants, which can be investigated further to discover promising molecules in the search for novel anthelmintic drugs and nutraceuticals.
