This experiment is aimed to define the best energy levels of ration for partridges during their reproductive phase by evaluating the feed intake, the average of eggs production and weight and feed conversion. Twenty-four Rhynchotus rufescens species, with 10 months of age, were fed with three isoproteic rations (15% crude protein) with different levels of metabolized energy (2,650; 2,800 and 2,950 kcal ME/kg). A completely randomized experimental design with three treatments and four replicates with a couple of birds per experimental unit was used. The results show that there was no significant difference in feed intake, but there was a significant effect of energy level on the mean of eggs weight, egg production and feed conversion for 2,650 and 2,800 kcal ME/kg as compared to the level of 2,950 kcal ME/kg. It was concluded that energy levels from 2,650 to 2,800 kcal ME/kg would be recommendable for partridge during their reproductive phase.
