“…There was no significant effect of nutritional plans on breast yield. Data from this research corroborate those of Pinheiro et al (2015), who did not observe differences in breast yield of quail fed different protein levels (19,21,23,25,27% CP) when the diet was supplemented with essential amino acids. However, these findings contrast with those published by Cavalcante et al (2010), who tested protein levels of 16 to 28% and found that the best level for breast yield in European quail was 17.8%.…”

“…Similarly, Pinheiro et al (2015) found that meat quail fed diets containing 23% CP showed better feed conversion for the period of 28 to 42 days of age. These findings differ from those found by Silva et al (2006), who observed better feed conversion in quail receiving a nutritional plan with a lower protein content (19.2%), supplemented with lysine, suggesting that the dietary protein for the period of 22 to 42 days can be reduced without impairing the use efficiency of the consumed diet.…”

In this study, we evaluated three nutritional plans for quail from 1 to 42 days of age on performance, carcass quality, and economic viability. A total of 210 European quail were distributed into three treatments in a randomized complete design with five replicates and 14 birds in each plot. The following three treatments were tested: nutritional plan 1 - one diet, provided from 1 to 42 days of age; nutritional plan 2 - two diets, provided from 1 to 21 and 22 to 42 days of age; and nutritional plan 3 - three diets, provided from 1 to 14, 15 to 35, and 36 to 42 days of age. Data were subjected to analysis of variance and means were compared by the Student Newman Keuls (SNK) test at the 5% probability level. At 42 days of age, one bird from each sex, of each experimental unit, was slaughtered to evaluate the yields of carcass, breast, legs, and abdominal fat. Nutritional plans per rearing stage with two or three diets provided similar production performances and better feed conversion than the plan including only one diet. Studied carcass characteristics did not differ between treatments. The nutritional plan with three diets provided the best economic viability. The best nutritional plan for meat quail was that containing three types of diet, because it provided a lower cost with feed per kilogram of quail produced without compromising performance or carcass characteristics.

“…Similar results were found by Pinheiro et al (2015) and Wen et al (2017), who reported that reducing the CP levels did not affect the yields of carcass, breast, or legs in European quail which received amino acid supplementation. However, Cavalcante et al (2010) observed a decreasing linear effect for leg yield at the CP levels of 16 to 28%.…”
