title: Protein requirements of Coturniz coturnix japonica for reproduction using purified diets.
abstract: Not more than 20% protein is needed in purified diets based on isolated soybean protein, starch supplemented with vitamins and minerals containing about 2700 kcal./kg. metabolizable energy for optimum egg production, fertility and hatchability. A protein level as low as 16% gave slightly inferior egg production, but the data were statistically insignificant. Levels of 24 and 28% protein were not superior to the 20% protein level for the reproductive performance.
