Performance, carcass characteristics and litter moisture in broilers housed at two densities Animal Sciences
Gopinger, Edenilse; Avila, Valdir Silveira de; Perondi, Dani; Catalan, Aiane Aparecida da Silva; Krabbe, Everton Luis; Roll, Victor Fernando Büttow.
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...
