“…These results are consistent with those of Costa et al (2008), who found no significant difference when analyzing levels of digestible lysine (0.88 to 1.20%) for Japanese laying quails. Conversely, Schmidt et al (2008) found a quadratic effect for this parameter in studies using different levels of digestible lysine in laying quails.…”

The objective of this study was to evaluate the existence of an interaction between lysine and arginine, and to determine their optimal ratio in the diets of Japanese laying quails. We used 480 quails with an initial mean weight of 180 g at 140 days of age. The quails were distributed in the experimental units in a completely randomized (3 × 2) factorial design, with three levels of digestible lysine (1.083, 1.183, 1.283%) and two levels of digestible arginine (1.472 and 1.580%). There were six treatments, with 10 replicates each, for a total of 60 experimental units. Rations, leftovers, and dead animals were weighed in order to calculate and adjust performance parameters. The variables analyzed were: daily diet consumption (DDC), laying rate (LR), average egg weight (AEW), egg mass (EM), feed conversion per egg mass and dozen eggs (FCEM and FCDE, respectively), weights of yolk, eggshell, and albumen (YW, ESW, and AW, respectively), relative yolk, eggshell, and albumen weights (RYW, RESW, and RAW, respectively), Haugh unit (HU), and marketable egg percentage (ME). There was no interaction (P > 0.05) between the levels of digestible lysine and arginine on the parameters analyzed; independently, these parameters were not affected by lysine and arginine levels. In conclusion, the optimal ratio of lysine and arginine in the diet of laying quails was 1.36: 1.00, which was the lowest used in the present study. Key words: Amino acids. Poultry. Amino acid interaction. ResumoObjetivou-se avaliar a existência de interação aminoacídica entre lisina e arginina, assim como, determinar a melhor relação entre eles em dietas para codornas japonesas em postura. Foram utilizadas 480 codornas com peso médio inicial de 180g aos 140 dias de idade. As codornas foram distribuídas nas unidades experimentais em delineamento inteiramente casualizado esquema fatorial (3x2) no qual foram utilizados três níveis de lisina digestível (1,083; 1,183; 1,283%) e dois níveis de arginina digestível (1,472 e 1,580%). Totalizando seis tratamentos com dez repetições cada, num total de 60 unidades experimentais. As rações, as sobras e os animais mortos foram pesadas a fim de calcular e ajustar os parâmetros de desempenho. As variáveis analisadas foram: consumo de ração diário (CRD), taxa de postura (TP), peso médio dos ovos (PO), massa dos ovos (MO), conversão alimentar por massa de ovos e por dúzia de ovos (CAMO e CADO), pesos da gema, casca e albúmen (PG, PC e PA), pesos relativos da gema, da casca e do albúmen (PRG, PRC e PRA), além da unidade Haugh (UH) e percentual de ovos comercializáveis (OC). Não houve interação (P>0,05) entre os níveis de lisina e arginina digestível sobre os parâmetros em análise, de maneira independente os níveis de lisina e de arginina também não afetaram os parâmetros em análise. Concluiu-se que a melhor relação de lisina e arginina para codornas em fase de postura foi a menor em estudo: 1,36:1,00. Palavras-chave: Aminoácidos. Aves. Interação aminoacídica.

“…A similar result was found by Costa et al (2008) and Sá et al (2007), who observed no significant variation in this parameter with increased lysine levels. Conversely, Rocha et al (2009) found a linear reduction (P < 0.05) in albumen as dietary lysine levels increased, and thus, the basal level (0.545%) provided the best response.…”

“…These results contradict those obtained by Costa et al (2009), who observed a quadratic effect on feed intake and feed conversion for 1 to 21-day-old laying quails, whose best estimate for feed conversion came from diets containing 11.00 g/kg of digestible threonine. Baylan et al (2006), evaluating the performance of 1 to 14-day-old Japanese quails fed different levels of total threonine, found no effect of total threonine on feed conversion, which is consistent with the present work.…”

Nutritional requirements of digestible threonine for growing meat-type quails

-The objective of this study was to estimate the nutrient requirements of digestible threonine for meat-type quails (Coturnix coturnix sp) in the growth phase. A total of 1350 not sexed meat-type quails were distributed in a completely randomized design with six threonine levels (10.80, 11.50, 12.20, 12.90, 13.60 and 14.30 g/kg as fed), five replications and 45 quails per experimental unit, from 1 to 14 days of age. The threonine levels in the diet had a quadratic effect on body weight, feed intake and weight gain. Estimates for highest body weight (79.41 g), feed intake (128.96 g/bird) and weight gain (70.73 g) were observed with diets containing 12.60 g/kg of digestible threonine. According to the LRP model, the threonine intake was estimated at 13.40 g/kg of digestible threonine. Protein deposition rate and energy retained in the carcass showed quadratic effect, with estimated digestible threonine levels of 11.80 and 12.00 g/kg in the diet for maximum protein deposition rate (2.00 g/bird) and retained energy in the carcass (15.88 kcal/g), respectively. There was a linear effect on feed cost per kg of live weight gain as threonine levels were increased. Nutritional requirement of digestible threonine for meat-type quails for maximum growth is 12.60 g/kg, corresponding to a digestible threonine:digestible lysine ratio of 67.02.

“…[17] found levels of digestible lysine for Japanese quails in production of 1.030% in diets formulated by the supplementation technique and without correction of the arginine/lysine ratio. Looking at the data, mentioned above, it is evident that the imbalance of the diets promotes diferent results among the authors [17,47,48].…”

“…However, the relative weight of quail eggs is higher, and may reach 10% of body weight. The weight of eggs of quails has a mean value of 12 g [17][18][19][20] and eggs of laying hens around 65 g [21][22][23][24].…”

The methodologies applied to chickens and laying hens, to determine the digestibility and requirement of protein and amino acids are used with quails, however, they need a more careful evaluation due to peculiarities inherent to the Coturnix genus, in order to provide consistent results. The nutritional requirements of the birds are determinate using the dose-response and the factorial method. Several mathematical models and techniques of diet formulation are allied to the dose-response method in determining nutritional requirements. The curvilinear (hyperbolic) models beter portray population behaviour in response to increasing nutrient doses in diets. The reading model, allow a beter estimation of the requirement, in relation to the mathematical models used in the dose-response method. The techniques of comparative slaughter and nitrogen balance are efective in determining the nutritional requirements of quails, however, the later need to be corrected by the loss of nitrogen in the feathers in determining the requirements of crude protein and amino acids for maintenance. The protein-free diet, coupled with the industrial amino acid supplementation, provides more robust digestibility values, since it more efectively predicts the endogenous excretion patern.
