Indigenous knowledge to mitigate the challenges of ticks in goats: A systematic review

The review collates the documented use of IK used in goats for controlling ticks and records the bioactivity testing that has been carried out on these plants. A literature survey was conducted on the use of IK whereby ethno-veterinary medicine (EVM) is used as well as on the investigations relating to the potential efficacy of the used plants. In Sub-Saharan Africa (SSA), ticks rank the first amongst the ectoparasites that limit goat productivity. Infrequent and overuse of acaricides have resulted in the development of resistance in ticks as well as environmental impacts. To combat these impacts, contribution of IK needs to be appreciated. In total 21, ethno-veterinary plant species, belonging to 16 families were identified to control ticks. These included plants such as Lippia javanica (Burm.f.) Spreng, Cissus quadrangularis .L, and Aloe ferox Mill, Grandifolia Warb, Terminalia brownii Fresen and Aloe volkensii Engl. Efficacy of plant species such as Pelargonium reniforme Curtis and Eucomis punctata L'Hér is enhanced by mixing them with substances like potassium permanganate and river salt to enhance the effectiveness of the extract. Ethno-veterinary plants have a wide range of phytochemicals, which include alkaloids, tannins, flavonoids, anti-microbial and pesticidal effects that produces tick repellent effects. The most common plant parts used during preparations are roots, leaves, barks, fruits and young shoots and to a lesser extent flowers, although the use of leaves usually takes precedence. Non-plant materials involve the use of methods such as traditional practices where ticks are manually removed. using hand picking. Oral administration and direct application on the infested site are used. It is, thus important to conduct more work on the conservation of ethnoveterinary plants, IK information gathering and dissemination.
