Abstract Effects of supplementing sheep consumingwheat straw with local agro-industrial by-products onfeed intake, growth, digestibility and nitrogen utiliza-tion were determined. Thirty 1-year-old local wethers,with a mean (SD) live weight of 19.8 (1.06) kg,were assigned to five treatments: wheat straw + atella(T1), wheat straw + atella + poultry litter (T2), wheatstraw+ atella + coffee pulp (T3), wheat straw + atella +coffee pulp + poultry litter (T4), hay + concentrate (T5).A 7-day digestibility experiment and a 112-day growthtrial were conducted. Total dry matter (DM) andorganic matter (OM) intake as well as body weightgain was similar for all treatments. The highest (P
