“…The same behavior was observed for the intake of lysine per bird (p < 0.05), indicating an increase of 10.256 grams of lysine per bird for each 0.1% increase in the lysine level, as determined by equation with R 2 = 99.81%, SSR=1.8 and AIC=13.08. Similar results were reported by Ton et al (2011), Ribeiro et al (2013), Nery et al (2015) and Lima et al (2016), who found, for Japanese quail, a linear behavior with precision of 99%, 100%, 98% and 98%, respectively.…”

“…For Japanese quails, Costa et al (2008) verified, through a linear model with precision of 60%, that with each increase of 0.1% of lysine, an increase of 0.5g in the feed intake occurred. Ribeiro et al (2013), Nery et al (2015) and Lima et al (2016) did not verify relationship between feed intake and digestible levels of lysine for Japanese quail. Table 2.…”

“…These results corroborate with those observed by Della-Flora et al (2012), who observed, for European quails, a percentage of laying of 86.65% for an optimal lysine level of 1.1137%, when using the quadratic regression model. Through the use of quadratic regression model, several authors explained the percentage of posture in Japanese quails with variable explanatory power, such as 75.0%, as observed by Lima et al (2016) with the supply of 1.18% lysine in the diet; 92.4% by Nery et al (2015) with 1.08% of lysine; and up to 96.0%, as obtained by Costa et al (2008) when they provided 1.03% of digestible lysine in Japanese quail diets.…”

“…The same was reported by Costa et al (2008) and Nery et al (2015) for Japanese quails. Nevertheless, when working with Japanese quails, Lima et al (2016) verified, through the linear model with a precision of 99%, that at each increment of 0.1% of lysine there was an increase of 13.5 g in feed conversion per dozen. Ribeiro et al (2013) verified a quadratic effect with explanatory power of 91%, for an optimal lysine level of 1.121%, which reflected in a feed conversion per dozen of 9.16g.…”

“…Della-Flora, Germano, Bavaresco, Lacerda, and Dionello (2012) verified an optimal lysine level of 1.1137% for European quail. For Japanese quail, Lima et al (2016) verified the optimal level with the supply of 1.18% of lysine in the diet; Nery, Castro, and Novoa (2015) with 1.08%; and Costa et al (2008) when providing 1.03% of digestible lysine.…”

The experiment was carried out to evaluate the productive performance of European quails (Coturnix coturnix) in the production phase, fed with diets containing different levels of digestible lysine. A total of 175 female quails, aged 65 days, were randomly distributed in a completely randomized design with five treatments and five replicates per treatment. The animals were housed in 25 metal cages, and each cage represented an experimental parcel, with seven birds per parcel. The birds were fed the experimental rations containing 1.177, 1.217, 1.317, 1.417, and 1.517% digestible lysine. The parameters evaluated were: laying rate, mass of eggs produced, feed intake in the period, lysine intake, feed conversion per dozen and per mass. Significant differences were observed for posture rate with quadratic behavior, which indicated higher production for the level of 1.23% of digestible lysine. There was an increasing linear behavior for the feed and lysine intake, and for conversion feed per dozen and by mass, we observed quadratic behaviors. This indicates better feed conversion index when the optimal inclusion level was 1.33% and 1.404% of digestible lysine in the diet, respectively. The requirement of digestible lysine in diets for European quails is 1.404%, which corresponds to a daily intake of 421.20 milligrams of digestible lysine.
