dc.description.abstractThis study was carried out to compare the effects of 2 dietary metabolizable energy (2600 and 2900 kcal/kg) and of 2 dietary crude protein contents (13% and 17%) on performance in breeder chukar partridges. A total of 144 breeder chukar partridges (48 males, 96 females), 36 to 52 weeks old, were used in the study conducted as a 2×2 factorial with a completely randomized design. Whereas food intake was significantly depressed in birds receiving a high energy diet, the dietary energy and crude protein contents exhibited no significant effect on growth performance (body weight and body weight gains). Food efficiency, egg weight, egg production, egg mass, fertility and hatchability were not significantly affected by the diet characteristics although a high crude protein content tended to enhance egg production and egg mass and that fertility seemed to be improved with a high matabolizable energy or a high protein level whereas hatchability tended to be inversely affected. A high protein or low energy diets tended to improve the food efficiency for performance. Finally, the nitrogen excretion was significantly additively affected by the dietary energy and protein contents, partridges fed with 2900 kcal/kg and 17% CP in die diet exhibiting a higher nitrogen excretion than the other groups. These results suggest that a diet containing 13% CP and 2600 kcal/kg as metabolizable energy may be supplied to partridges without modification of performance and with reduction of nitrogen excretion.en_US
