Proizvodna svojstva brojlera pri razliĉitoj razini sirovih bjelanĉevina i metaboliĉke energije u krmnim smjesama

A study was conducted to evaluate crude protein and energy level supply on female broiler production parameters. They were divided into three groups and placed in three separate pens. Control group which was fed a crude protein and metabolic level of 100%, and Group 1 which was fed on level 93, 5% and Group 2 on level 87%. Feed conversion (g gain/g feed), body mass, and gain improved as crude protein and energy levels increased. The relative proportion of muscle in the Control group and Group 1 was statically (P<0, 01) much higher than in Group 2. Biochemical parameters showed lower concentrations of triglycerides and creatinine in the groups fed feed mixtures with a lower level of crude protein and metabolic energy.
