The effects of different levels of dietary protein content and population density in growing pheasants, up to the age of 42 days, on production results and mortality have been studied. The experiment was set as a two factorial study (2x2). Factor A was the influence of crude proteins in diet (A1 = 26% up to 4 weeks of age and 20% from 4 up to 6 weeks of age; A2 = 30% crude proteins up to 4 weeks of age and 24% from 4 up to 6 weeks of age). Factor B was population density (B1 = 450 birds/group and B2 = 550 birds/group). The total number of birds in trial was n=2000. Body mass was measured at hatching, 15 and 42 days of age. Up to 15 days of age the pheasants were housed in cages, but thereon they were reared under floor conditions with free access to outdoors. Based upon of obtained results and the previously published literature data it can be concluded that feedstuff protein content is the key factors required in order to obtain satisfactory final body weight and subsequently good quality material for the repopulation of hunting grounds.
