In order to establish an optimal density per unit area, and the effect of administration of a selenium vitamin-mineral supplement in the diet of young quails during 0-14 days of life, an experiment was organized on an initial number of 1200 chickens one day old of Balotesti population between the ages of 1 and 42 days. For the experiment chicks were divided into four equal groups, namely a control group (300 chicks) and 3 experimental groups (each 300 chicks per group). Following research is recommended to use a density per unit area that decreases faster during the growth, of 300 chickens / square meter during 0-3 days of growth, 200 chickens / sq. m during 4-7 days of life, 150 chicken / sq. m during days 8-21 and of 100 chickens / sq. m during 22-42 days. This leads to superior results with over 10% in young quails mass growth, with a reduction in death rate of 20%, without significant influence over combined feed consumption and feed utilization. Small differences of only 2.47% in live weight, 2.34% in average daily gain, 1.23% in combined feed consumption, by 2.72% in specific consumption and considerable effect of 3% in the death rate of the group with the same low experimental density, recommends the administration of a vitamin-mineral product with selenium in young quails growing, while used density above. Administration of selenium had a greater influence on death rate, which was reduced by 13.7% in the group with high density, equal to that of the control group.
