Níveis de energia metabolizável e de metionina em rações para codornas (Coturnix coturnix japonica) em postura. Acta Scientiarum. Animal Sciences, Maringá, v. 20, n. 3, p. 407-411, 1998.e- 1807-86721806-2636http://repositorio.bc.ufg.br/handle/ri/12916This experiment was carried out to evaluate the effects of the combination of three levels of metabolizable energy (2.700, 2.850 and 3.000kcal/kg) and two levels of methionine (0.45% and 50%) in rations for Japanese quails during the laying period. The results of the experiment did not show any statistically significant difference for the productive factors. Only for 0.50% methionine level, the values of average egg weight were higher and feed conversion rates were lower (both dozen eggs and egg mass) when compared to 0.45% methionine rations.porAcesso AbertoCodornas japonesasDesempenho produtivoEnergia metabolizávelMetioninaJapanese quailPerformanceProductiveEnergyMetabolizable methionineArtigo
