Résumé partiel
Gastrointestinal nematodes (GIN) constitute a huge challenge to goat productivity worldwide, leading to production losses. Anthelmintic drugs have been used to control GIN, but their effectiveness has been reduced due to their high cost, scarcity in resource-limited farms, and drug resistance and residue challenges. Therefore, other sustainable control measures that are cheaper, readily available, and not chemically manufactured, such as indigenous knowledge (IK), are required. The broad objective of this study was to investigate IK methods and practices used to control gastrointestinal parasites in goats. Face-to-face interviews were conducted on IK experts in Jozini Municipality, KwaZulu-Natal, South Africa. Experts used IK because it is part of their culture, locally available and guaranteed to work. Indigenous knowledge was sourced from their forefathers through oral communication and training. Traditional healers had more sources of IK, including visions, dreams and spirits. Experts identified GIN as the most common parasites in goats. They used shape, size and colour in the identification of parasites. Indigenous knowledge was used to identify symptoms caused by GIN infestations. Thirty-three plant species were identified to control worm burdens in goats. A cross-sectional survey was used to determine the extent of IK used to control gastrointestinal parasites in goats. Cissus quadrangularis Linn. was the most widely used plant (67 %), followed by Albizia anthelminthica Brongn. (47 %), Cissus rotundifolia (Forssk.) Vahl (42 %), Vachellia xanthophloea (Benth.) P.J.H. Hurter (38 %), Aloe marlothii A. Berger (38 %), Sclerocarya birrea (A. Rich.) Hochst (36 %), Gomphocarpus physocarpus E. Mey (36 %), Aloe maculata All. (35 %), Trichilia emetica Vahl (33 %), Aloe ferox Mill. (32 %), Vernonia neocorymbosa Hilliard (20 %) and Schkuhria pinnata (Lam) Kuntze ex Thell (16 %). The odds of farmers using IK in the dry environment were 7.9 times more likely than in the wet environment
