For the growth periods (one to seven, eight to 14 and 15 to 21 days old) quails were created in mixed batches, and fed a basal diet containing 0.76 g methionine + cystine, supplemented with five levels of DL-Methionine, corresponding to the relations M+C: digestible Lys 0.61, 0.66, 0.71, 0.76 and 0.81. For final periods (22 to 28 and 29 to 35 days old), quails were created in sexed lots, and received basal diet containing 0.63 g methionine + cystine, supplemented with five levels of DL-Methionine, the corresponding to the relations M+C: digestible Lys 0.68, 0.73, 0.78, 0.83 and 0.88. The experimental design was completely randomized with five treatments and eight replicates. In periods of one to seven and eight to 14 days of old was observed effect of the relations M+C: digestible Lys for all performance traits, except for viability of quails. During the period of 15 to 21 days, the growth relations M+C: digestible Lys influenced all traits, except the uniformity and viability of quail. There was no effect of the relations M+C: digestibles Lys in the period 22 to 28 days for male quails, however, for females observed effect on feed intake and weight gain. In the period 29 to 35 days for males, there was effect for feed intake, methionine and cystine intake, weight gain, carcass ether extract, thigh + drumstick yield, carcass crude protein and nitrogen balance. However, for female quails 29 to 35 days of old, there was no effect on any of the traits studied in the face of relations M+C: digestible Lys. The relations M+C: digestibles Lys which optimized the weight gain were 0.81, 0.75 and 0.77 for periods of one to seven, eight to 14 and 15 to 21 days of old, respectively, for quail both sexes. During periods 22 to 28 and 29 to 35 day old females quails are recommended relations of 0.79 and 0.68, respectively, and for males quails are recommended relations of 0.68 and 0 88 M+C: digestible Lys.

As aves foram alojadas em 30 boxes (?rea de abrigo), com acesso ? ?rea de pastejo. Em cada experimento foram utilizados 630 frangos e o delineamento experimental utilizado foi inteiramente casualisado, em esquema fatorial 5x2 (n?veis de lisina x sexo) e tr?s repeti??es de 21 aves cada. Os n?veis de lisina digest?vel avaliados foram: 8,1; 9,5; 10,9; 12,3 e 13,7(g/kg) na fase inicial; 7,07; 8,07; 9,07; 10,7 e 11,07 (g/kg) na fase de crescimento I; 6,07; 7,07; 8,07; 9,07 e 10,07 (g/kg) na fase de crescimento II e 6,0; 7,0; 8,0; 9,0 e 10,0 (g/kg) na fase final. As vari?veis de desempenho avaliadas foram: consumo de ra??o (CR, g/ave), consumo de lisina (CL, g/ave), ganho em peso (GP, g/ave) e convers?o alimentar (CA, g ra??o consumida/ g de ganho em peso). Foram avaliadas as vari?veis de carca?a e de qualidade da carne: rendimento de carca?a, peso da gordura, rendimento e peso dos cortes de peito, de asa+coxinha e de coxa+sobrecoxa, o potencial hidrogeni?nico (pH), a capacidade de reten??o de ?gua (CRA), a perda de peso por cozimento (PPC), a maciez objetiva (MO) cor e luminosidade (L*, a*, b*). Para o per?odo inicial, recomenda-se o n?vel de 12,95 g de lisina/kg, na ra??o de machos e f?meas para melhor CA. Na fase de crescimento I, recomenda-se 9,61 g de lisina/kg na ra??o para minimizar a CA de ambos os sexos, e, para melhor GP, os n?veis de 10,08 e 9,49 g de lisina digest?vel/kg na ra??o de machos e f?meas, respectivamente. Verificou-se que, para a fase de crescimento II, o n?vel de 6,0 g lisina/kg de ra??o atende ?s exig?ncias dos frangos. Para a fase final, observou-se efeito dos n?veis de lisina digest?vel para a CA, sendo recomendados 8,51 g de lisina/kg de ra??o. Para as vari?veis de rendimento de carca?a obteve-se efeito linear crescente de lisina sobre o rendimento de coxa + sobrecoxa das f?meas. A MO da carne de coxa aumentou, linearmente, com os n?veis de lisina, e, para a CRA e L* da carne do peito, observou-se efeito linear decrescente dos n?veis de lisina. / Disserta??o (Mestrado) ?

The birds were distributed into 30 pens (shelter area) with access to the pasture. In each trial, 630 birds were used and the experimental design was a completely randomized in a factorial arrangement 5 x 2 (levels of lysine and gender), with three replicates of 21 birds each. The digestible lysine levels evaluated were: 8.1; 9.5; 10.9, 12.3 and 13.7 (g/kg) for initial phase, 7.07, 8.07, 9.07, 10.07 and 11.07 (g/kg) for growing phase I, 6.07, 7.07, 8.07, 9.07 and 10.07 (g/kg) for growing phase II and 6.00, 7.00, 8.00, 9.00 and 10.0 (g/kg) for the last phase. The performance parameters evaluated were: feed intake (FI, g/bird), lysine intake (LI, g/bird), weight gain (WG, g/bird) and feed convertion (FC, g feed intake/ g weight gain). There was evaluated carcass parameters and meat quality: carcass yield, fat weight, yield and weight about the cuts (breast, wing + drumstick, thigh + drumstick), hydrogen potential (pH), water holding capacity (WHC), cooking loss (CL), tenderness, color and brightness (L*, a*, b*). For the initial phase we recommend the level of 12.95 g of lysine/ kg, on the ration for males and females to improve FC. In the growing phase I, we recommend 9.61 g of lysine/kg in the ration to minimize FC for both genders, and to improve WG the levels 10.08 and 9.48 g of digestible lysine/kg on the ration for males and females, respectively. We verified that for growing phase II, the level of 6.0 g of lysine/kg on the ration meets the chicken?s requirements. At last phase, there was digestible lysine effect for FC and can be recommended 8.51 g of lysine/ kg. For yield carcass parameters, there was an increasing linear effect of females? thigh + drumstick. The tenderness increased linearly with lysine levels and for WHC and L* of the meat breast there was a decreasing linear effect of lysine levels.

Foram realizados cinco experimentos, conduzidos no setor de Avicultura da UFVJM, no Campus JK, em Diamantina ? MG. As aves usadas nos experimentos foram todas machos, da linhagem Cobb 500. No total, foram usadas 2.430 aves e consideradas as fases de 1 a 7, 8 a 21, 22 a 35, 36 a 42 e 42 a 49 dias de idade. Em todos os experimentos, as aves foram distribu?das segundo um delineamento experimental inteiramente casualizado, com seis tratamentos (T1 ?

We conducted five experiments, conducted in the experimental aviary of UFVJM on campus in JK Diamantina - MG. The birds used in the experiments were all male, the strain Cobb 500. In total 2430 birds were used and considered stages 1-7, 8-21, 22-35, 36-42 and 42-49 days of age. In all experiments, the birds were distributed according to a completely randomized design with six treatments (T1 - diet control and formulated in accordance with recommendations of Rostagno et al. (2011) to meet crude protein and digestible amino acids, T2 - diet 5% reduction in crude protein diet control, T3 - diet with 10% reduction of crude protein in the control diet; T4 - diet with 15% reduction of crude protein in the control diet; T5 - diet formulated to meet the requirements the digestible amino acids of diet control with the amount of crude protein free; T6 - diet formulated to meet the amount of crude protein diet control with the amount of digestible amino acids free). In the period from 42 to 49 days were three replicates, but in the other phases were used four replicates per treatment. The performance of the birds, it was observed that, with the assistance of digestible amino acid requirements can be reduced up to 10% of the crude protein nutritional recommendations made by Rostagno et al. (2011), that performance is not affected. However, diets formulated to meet only the requirements of digestible amino acids, decrease the performance of the birds. In general, no differences in energy consumption, however, the consumption of protein and amino acids differ as altered levels of crude protein and digestible amino acid diets. The decreased levels of dietary crude protein up to 15% did not affect carcass yield and cuts, but the diet formulated to meet only the requirements of digestible amino acids, caused decrease in carcass and breast meat of birds. The feathering of the birds was not affected by the diets evaluated. The cost analysis performed showed that diets formulated to meet crude protein have a lower cost, however, up to 35 days, a reduction of up to 10% of the crude protein supplementation with digestible amino acids, improve the cost of weight gain birds.

Two lines of cutting quails, LF1 and LF2, were used to perform the experiment. The feed provided in the growing period, from birth to 21 days, contained a 0.20% tryptophan:lysine ratio and in the final growth period, from 22 to 35 days of age, quails were separated into 5 treatments containing the Ratios of 0.15; 0.20; 0.25; 0.30; 0.35% tryptophan: lysine. The birds were weighed at 28 and 35 days of age and slaughtered at 35 days of age. The evaluated characteristics were the pre-slaughter weights, weight 28, weight 35, weight and yields of the carcass, breast, thigh + sobrecoxa and the quality traitsof the meat. The analyzes were performed using random regression models considering fixed sex effect and direct additive genetic random effect as functions of the tryptophan:lysine ratios of the diet, assuming homogeneity of residual variance. The results for performance, carcass traitsand meat quality traitsindicate that the regression coefficient of the intercept (b0) was higher than the random regression coefficient (b1). Heritability and additive genetic variance were influenced by the different tryptophan:lysine ratios of the diet. There was no genotype x environment interaction for the traitsof carcass yield, yield of breast and yield of thigh + overcoat. The quality traits of the meat CRA, b *, c * and H * (LF1) and CRA, PPC, L * and H * (LF2) presented genotype x environment interaction. It is possible to conclude that for yield traitsthe selection can be made in the lowest tryptophan: diet lysine ratios. For meat quality traitsthe sensitivity of the values indicates that the selection must be made in the tryptophan:lysine ratio in which the quails will be created.
