THE INFLUENCE OF FEED PROTEIN LEVEL ON PRODUCTIVE PERFORMANCES AT ROSS 308 HYBRID
Few years ago our country start breeding broiler hybrids due to the high growing performances. In our experiment the influence of protein ration level on growing performances and slaughter yield hybrid Ross 308, were performed. The two experimental lots were keeping in optimum microclimate condition...
