Protein supplement potential of Dodonaea angustifolia leaves by replacing atella on nutrient utilization and performance of Farta sheep fed natural pasture hay basal diet.

Background: Protein feed resources for ruminant animal productions are deficit in Ethiopia.

Objectives: To evaluate the supplementation effects of dried Dodonaea angustifolia leaves (DDL), dried traditional brewery by-product locally called atella and their mixtures on nutrient utilization and growth performance of Farta sheep fed natural pasture hay (NPH) as basal diet.
