The study sought to test and evaluate the efficacy of lagundi and banaba fresh leaves extracts against gastro-intestinal parasites of goat and compare it with the commercial dewormer. The data collected includes species of gastro-intestinal parasites, parasitic loads, efficacy of the test extracts, hatchability of parasitic eggs, and return above dewormer costs. The treatments used were as follows: GT1 (Control) – Grower goats administered with Valbazen (Albendazole); GT2 – Grower goats administered with Banaba leaves extract (BLE); GT3 – Grower goats administered with Lagundi leaves extract (LLE); MT1 (Control) – Matured goats administered with Valbazen (Albendazole); MT2 – Matured goats administered with BLE; and MT3 – Matured goats administered with LLE.  There were five (5) species of gastro-intestinal parasites identified in both stages of goat, the Cooperia spp., which is the most abundant, followed by Strongyloides spp., Haemonchus spp., Monieza spp., and Trichuries spp.. The parasitic loads of the experimental animals were rated as heavily parasitized. In terms of efficiency of the leaves extracts and commercial dewormer against Haemonchus spp., the Treatments GT2, GT3 and MT2 were rated effective and Treatment MT1 was rated highly effective. In Cooperia spp., the efficacy of Treatment GT1 was effective, Treatments MT2, MT3 and GT3 moderate effective and Treatment GT2 highly effective. Lastly, in Monieza spp. Treatments GT1 and GT3 were rated as highly effective and GT2 effective. In larval culture, there were no ovicidal and larvicidal effects of the test extracts and commercial dewormer in parasitic eggs. It is recommended that immediate anti-parasitic treatment should be administered to the test animals to control or eliminate parasitism. To reduce the development of dewormer resistant parasites, interval use of dewormers should be adopted. To prolong the effects of the test extracts and commercial dewormer, short intervals or frequency of administration should be applied to the test animals and studies on the different doses, frequency, combination of lagundi and banaba leaves extracts as dewormer and the use of different species of experimental animals should be conducted to identify the effects of test extracts.
