An experiment was carried out to estimate dietary crude protein and energy requirements of 128 females of Japanese quails from 15 to 32 days of age, by the factorial method. A completely randomized design with four treatments with four replicates of eight birds was used. The treatments were: T1 = basal diet (BD) with 24.1% CP and 2,900 kcal AMEn ad libitum, T2 = 80%, T3 = 60% and T4 = 40% of T1 (close to maintenance). In the beginning […]

This experiment was carried out to estimate the crude protein and metabolizable energy requirements for maintenance and gain of 384 females of Japanese quails from 1 to 12 days of age. A completely randomized design with four treatments, with six replicates of ten birds each, was used. The treatments were: T1 = basal diet (BD) with 28% CP and 2,900 kcal AMEn ad libitum; T2 = 80%; T3 = 60% and T4 = 40% of ad libitum (close to maintenance). […]
