Phytogenic feed additives are being considered in the study because their nutritional compositions and functional properties. Proximate composition and mineral contents of two herbs were investigated. The results of the present study showed that the Rosemary leaf powder contained 91.5% dry matter, 5.15% crude protein, 15.20% ether extract, 4.52% crude fiber, 7.50% total ash, 67.63% nitrogen free extract, 1.7% acid insoluble ash, 2.2% Calcium and 0.5% Phosphorus and Black cumin seed powder contained 97.21% dry matter, 20.40% crude protein, 15.69% ether extract, 7.73% crude fiber, 4.98% total ash, 51.20% nitrogen free extract, 0.26% acid insoluble ash, 1.74% calcium and 0.03% phosphorus. The proximate analysis revealed that Rosemary contain low level of crude protein but Black cumin seed rich in crude protein content and both herbs could be used as a potential alternative source of antibiotics and unconventional natural protein source in poultry feeds.
