Abstract

The aim of the present experiment was to evaluate performance and biometrics of French quails viscera in initial phase (0 to 14 days). A total of 3,768 one day-old quails were submitted to diets in different levels of crude protein and metabolizable energy. The utilized design was entirely randomized in a 2x4 factorial, in two levels of metabolizable energy (2,900 and 3,000 kcal ME/kg), four levels of crude protein (20.5; 21.5; 22.5 and 23.5%), and three replications of 157 quails per experimental unit. Over seven days, no significant differences were verified in parameters of weight gain, feed intake and feed conversion. However, by 14 days, feed intake, feed conversion and mortality were influenced by the metabolizable energy. In the biometric study, pancreas and gizzard weight presented significant differences at seventh and fourteenth days during the treatments. Crude protein levels influenced liver weight.
