Abstract Background Currently, there is an increase in the usage of phytogenic feed additives to help improve animal welfare and productivity, while less emphasis is now placed on metabolic and oxidative stability of neuronal and testicular tissues. This study aims at investigating the effects of Moringa oleifera, Phyllanthus amarus and Viscum album as feed additives on some metabolic indicators and oxidative status of rabbit testis and brain. Isonitrogenous and isocaloric diets were formulated with 5% supplementation of each of the phytogenic additive to 3 treatment groups and basal diet group. Results It was revealed that moringa, mistletoe, and phyllanthus can modulate oxidative status in both the brain and gonads of rabbit bucks through their unique phytochemical compositions, thereby affecting reproductive and cognitive functions. Moringa, rich in crude protein, saponins, glycosides, and steroids, enhances protein and lactate dehydrogenase levels but increases lipid peroxidation in the testis. Mistletoe, with high crude fiber, ash, and antioxidants like flavonoids and tannins, boosts total antioxidant activity in several brain regions and reduces lipid peroxidation, indicating its potential for reducing oxidative stress. Phyllanthus, having the least fiber and ash but effective antioxidant properties, notably affects the oxidative balance in both the testis and brain, with varied impacts on different tissues. The result obtained showed that total antioxidant activity of the left testis was enhanced (p 0.05) to bucks on basal diet. Bucks fed on moringa and phyllanthus additives had higher (p |
