The objective of this research was to determine the influence of the bird density: 10, 12, 14 and 16 birds/square meters on broilers performance, during winter time. After 21 days, the feed consumption was affected by different densities. The highest feed consumption was found on the lowest bird density (10 birds/square meters). The body weight was influenced by the density after 35 days. The lowest body weight was obtained on the highest density (16 birds/square meters). However, the carcass yield was not affected by density. The feed conversion was not affected significantil, When the body weight was reduced, the food intake was decreased too. The viability was not influencied by the densities. The economic analysis concluded that a linear benefit was found in increasing the bird density by 10 to 16 birds/square meters.
