<b>Performance, carcass characteristics and litter moisture in broilers housed at two densities

Resumo

The effect of stocking density in broiler chickens (11.08 and 13.20 birds m^-2), between 5 and 45 days of age, was assessed with regard to performance, cut yield, litter moisture and frequency of pododermatitis injuries. Further, 476 one-day chicks Cobb 500^® were distributed in a completely randomized design at two densities (birds m^-²), with seven replications per treatment in 14 experimental units. Birds housed at a lower density (11.08) increased feed intake (p < 0.05), without any effect on weight gain and feed conversion. Retail yields were not influenced (p > 0.05) by treatments. In the case of higher density (3.20)the litter showed higher moisture content (p < 0.05) at 28 and 35 days of age. There was a higher occurrence of pododermatitis in birds housed at a density of 13.20 birds m^-2. Results show that increased housing density from 11.08 to 13.20 birds m^-2 does not affect growth performance, carcass yield and cuts. However, a housing density of 13.20 birds m^-2 increased litter moisture and provided a higher occurrence of grade I pododermatitis.
