HURTADO-NERY, Víctor L.; TORRES-NOVOA, Diana M.  and  DAZA-GARZON, Marciano F.. The effect of crude protein and metabolisable energy levels on quail egg quality. Orinoquia [online]. 2015, vol.19, n.2, pp.195-202. ISSN 0121-3709.

This work was aimed at evaluating the effect of raw protein and metabolisable energy levels on characteristics regarding Japanese quail (Coturnix japonica) egg quality. A completely randomised experimental design involved using 864 quail eggs in a trial having a 4x4 factorial arrangement, four levels of metabolisable energy (2,750, 2,850, 2,950 and 3,050 kcal EM/kg) and four levels of raw protein (RP) (17.5, 19.0, 20.5 and 22.0%) with three repeats. Six samples of three eggs per experimental unit were taken at four-weekly intervals. Protein and energy levels did not influence the variables studied here (p>0.05). Diets having 17.5% to 22% RP and 2,750 to 3,050 kcal EM/kg energy levels thus did not affect egg quality characteristics.

Keywords : Feed conversion ratio; Coturnix; nutritional needs; egg production.
