Abstract
This paper reviewed the effects of Aspilia africana (African marigold plant) on animals. Aspilia africana is one of many plants which are fast gaining recognition as feed for animals because of its many benefits, although, there are some identified deleterious effects associated with its use. Studies have shown that the plant has positive influence on different species of animals with regards to growth, carcass yield, egg and meat quality attributes. Several findings indicate that Aspilia africana might stimulate erythropoiesis; improve haematological and serum biochemical parameters, boost immunity, stimulate lactation, enhance metabolism, and wound healing but contains anti-nutritional factors and might inhibit manifestation of oestrus, implantation and conception in female animals. The plant has also been reported to be deleterious to fertility in male animals with manifestation of toxicity in some organs. Therefore, Aspilia africana could be used as growth promoter, immunity booster, lactation stimulant, wound healing agent, agent in the management of anaemia, but should not be fed to breeding animals until the discovery of anti-dote (s) which can suppress or neutralize its anti-fertility effects.
