Sažetak
The breeding in controled conditions is a usual measure for the maintaining of the optimal population size in the hunting area. The production of good quality pheasants in artificial breeding depends on the correct treatment, especially regarding their diet, and population density. The paper deals with the influence of diet on 42 day old pheasants in artificial breeding. Two mixtures with two levels of proteins (with 30% and 26% crude protein) until the age of four weks and then were used mixtures with 24%, and 20% of crude proteins. Every level of proteins is used for two densities, 550 and 450 units perbox, so pheasants was performed on four groups of pheasants. The meassurement of body mass of live pheasants was performed three times: 0. day, 15. day and 42. day after establishment of experiment and beetwen groups are statistically significant differences (p<0.01). In this work are showed body mass, body mass increase, daily consumption per pheasant and food consumption for production one kilogram of growth and mortality.
