Abstract: Jathropha tanjorensis popularly known as hospital is too far and Psidium guajava (guava leaf) are plants of interest containing promising phyto-additives with the potentials to improve pork quality and carcass traits. This study evaluated the effects of Jathropha tangorensis and Psidium guajava leaf meals on pork quality in terms of sensory attributes, chemical composition, and carcass traits. In a completely randomized design, twenty-four grower pigs (21.81±2.15 kg) were randomly assigned to three dietary treatments with eight (8) pigs per treatment and further replicated twice (4 pigs per replicate). The dietary regimens were as follows: the basal diet group, which served as the control, the Jathropha tanjorensis Leaf Meal (JTLM) and Psidium guajava Leaf Meal (PGLM) groups. The additives were included at 3% of body weight, with two replicates of four pigs per regimen. Results showed JTLM and PGLM significantly (P
