Experimental treatments including five doses of dietary lysine (9.40, 10.9, 12.4, 13.9 and 15.4\u00a0g\/kg of diet) were used in a dose\u2010response platform from 7 to 21\u00a0day of age. A total of 375, 7\u2010day old quail chicks were randomly allotted to one of five dietary treatments with five replicate pens and 15 birds per pen. Performance traits including feed intake (<jats:styled-content style=\"fixed-case\">FI<\/jats:styled-content>), weight gain (G) and feed:gain (F:G) and carcass criteria including dressing (<jats:styled-content style=\"fixed-case\">DRS<\/jats:styled-content>), breast meat yield (<jats:styled-content style=\"fixed-case\">BMY<\/jats:styled-content>) and leg meat yield (<jats:styled-content style=\"fixed-case\">LMY<\/jats:styled-content>) were measured and used to fit several models (e.g., spline and quadratic polynomial models).
