The research results on 3 protein levels (16 - 18 - 20 percent) with 3 energy levels (2,400 - 2,500 - 2,600 kcal/kg) in the dietary for reproducing ostriches and 12 protein levels with 12 energy levels in 4 periods of meat-type ostriches indicate that:The dietary comprising the protein level of 20 percent with the energy level of 2,500 - 2,600 kcal for reproducing ostriches in Vietnam is appropriate and the best in terms of the production possibility of 1-day old breed ostriches/female/year, respectively resulting in 19.87 and 21.03 birds.It is the most effective to apply the nutrition level for meat-type ostriches at 1 - 3; 4 - 6; 7 - 9; 10 - 12 months of age with the protein level of 19; 17; 15; 13 percent and the energy level of 2,800; 2,600; 2,500; 2,300 kcal/kg of feed. It is the most appropriate to slaughter at 10 - 12 months of age.
