This work was developed to evaluate the effect of different levels of crude protein (CP) and metabolizable energy (ME) on the performance of laying quails. Six hundred and seventy tywo Japanese quails (Coturnix coturnix japonica) from 42 days to 168 days of age were divided in six periods of 28 days each. The birds were assigned to a completely randomized design, with the treatments in a factorial arrangement of 4 x 4 (protein x energy), with six replication of seven […]

Four hundred and fifty quails of each sex, in a total of nine hundred quails, were assigned to a completely randomized design with five replicates of six quails per experimental unit, to estimate the crude protein (CP) and metabolizable energy (ME) requirements for maximum performance of females and males Japanese quails reared for meat production purpose and to determine the best slaughter age. The treatments were consisted of the quails sex and the experimental diets, resultant from the combination of […]

To evaluate the use of rations with different corn and soybean meal eparticle size in productive performance, 384 Japanese quails in laying period with 13 weeks of age were allotted to laying cages. The traits consisted of different particle size of diets according to grinding size of corn (C) and soybean meal (SBM), with the use of sieve diameter of 1/8, 2/8 inches or 6 mm resulting in a GMD of 1420, 1161 and 1047 mm, respectively, and for soybean […]
