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.

Evaluation of nutritional plans for meat quail

“…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%.…”

“…According to [33], meat pH is one of the main factors that affects its color as well as its physical structure, light reflectance properties, water retention capacity, tenderness, cooking weight loss, juiciness, and microbiological stability. The values found were similar to the reference values (5.6 to 5.9) recommended in the literature [25,34], indicating no interference of the diet in these aspects.…”

The objective of this study was to investigate the impact of alternative lipid sources on nutrient metabolism, performance, carcass characteristics, and meat quality in European quails. Trial 1 determined the energy values and nutrient metabolizability of non-conventional lipid sources. Six treatments (control, soybean oil, conventional corn oil, distilled corn oil, poultry fat, and beef tallow) were randomly assigned with 10 replicates per treatment. Trial 2 evaluated animal performance, carcass characteristics, and meat quality using a randomized design with five treatments and 10 replicates each. Statistical analysis showed no significant difference in apparent metabolizable energy corrected by nitrogen (AMEn) and coefficients of metabolizability (CM%) among the lipid sources. The AMEn values found were 8554 for soybean oil, 7701 for corn, 7937 for distilled corn oil, 7906 for poultry fat, and 7776 for beef tallow (kcal/kg). The CM values were 88.01% for soybean oil, 79.01% for corn oil, 84.10% for distilled corn oil, 81.43% for poultry fat, and 79.28% for beef tallow. The inclusion of lipid sources of plant and animal origin in the diet of 7–35-day old meat quails did not influence performance or carcass and cut characteristics. The inclusion of distilled corn oil increased carcass yield and influenced skin and meat color parameters. AMEn values varied for each lipid source. The inclusion of distilled corn oil positively influenced skin and meat color as well as carcass yield in quails.
