| Phosphorus is an important mineral for optimum growth and bone mineralization and is considered the third most expensive nutrient in diets for nonruminants. An experiment was conducted to evaluate the available phosphorus requirements (AP) for meat-type quail in the starter phase (1 to 21 days old). One-day-old, unsexed European quail (375) from the LF1 lineage were used for the study and were housed in pens. The experiment had a completely randomized design, with five treatments (0.13, 0.23, 0.33, 0.43 and 0.53% of AP), each of which included five replicates in 15 birds. Feed intake, weight gain, feed conversion ratio, and the tibial deposition of phosphorus, calcium, and ash were assessed. The AP levels influenced all studied variables. We calculated... |

| ABSTRACT: The objective was to estimate the most appropriate digestible methionine + cysteine:lysine ratios for growing meat-type quails (Coturnix coturnix) from 1 to 21 days of age. Quails were fed with a basal ration deficient in digestible methionine + cysteine, with five levels of DL-methionine, in substitution of glutamic acid and starch, resulting in digestible methionine + cysteine:lysine ratios of 0.61, 0.66, 0.71, 0.76 and 0.81. Feed and methionine + cysteine intake, body weight gain, feed conversion and uniformity were assessed. From 1 to 7 days, an increasing linear effect was observed for feed and methionine + cysteine intake, body weight gain, and uniformity, and a linear decrease for feed conversion. From 8 to 14 days, the 0.70 methionine +... |

| Objetivou-se avaliar diferentes níveis de proteína bruta e a suplementação de aminoácidos essenciais sobre o rendimento de carcaça e a qualidade da carne de peito de codornas de corte dos 28 aos 42 dias de idade. O delineamento utilizado foi inteiramente casualizado, com cinco tratamentos (19, 21, 23, 25, 27% PB), cinco repetições e 12 aves (seis fêmeas e seis machos) cada. Aos 42 dias de idade, quatro aves de cada parcela foram abatidas e avaliadas quanto ao rendimento de carcaça quente (RCQ) e resfriada (RCF), de peito (RP), de coxa e sobrecoxa (RCS), potencial hidrogeniônico (pH), capacidade de retenção de água (CRA), perda de peso por cozimento (PPC), cor e luminosidade e maciez objetiva (MO) do músculo. Observou-se efeito dos níveis de PB em todas as... |
