Digestible lysine requirement for European laying quail

“…The percentage of posture behaved in a quadratic manner, with the maximum production of 77.79% when the percentage of lysine included in the diet reached the optimum level of 1.233%, as determined by the equation , which presents power of explanation of 99.78%, SSR = 38.65 and AIC = 30.41 (Table 3). 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.…”

“…Ton et al (2011) verified linear behavior with 93% of precision power for feed conversion in European quail. Barreto et al (2006) and Della-Flora et al (2012) found, in European quails, that there was no difference in feed conversion per mass in relation to the different levels of digestible lysine, and the same was found by Costa et al (2008), Ribeiro et al (2013) and Nery et al (2015) for Japanese quails.…”

“…There was a difference of feed conversion per dozen between the digestible lysine levels (p < 0.05), with a quadratic behavior yielding the best conversion index of 474.41g of feed per dozen eggs produced, when the optimal level of lysine inclusion in the diet was 1.404%, as determined by equation with R 2 = 99.76%, SSR = 26.81 and AIC = 51.61. Della-Flora et al (2012) working with European quails, did not find differences between the levels of digestible lysine. The same was reported by Costa et al (2008) and Nery et al (2015) for Japanese quails.…”

“…Several authors performed studies evaluating the introduction of digestible lysine for eggs production in diet for European and Japanese quails. 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.…”
