Metabolizable energy and methionine levels in rations for quails (Coturnix coturnix japonica) during laying period

This 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 stat...

Sumario:This 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.
