Effect of stocking density and shed area on welfare indicators in broiler chickens

The aim of this work was to evaluate the effect of decreasing stocking density and shed area on footpad dermatitis, hock burn, and ventral feathers cleanliness of broilers reared in winter. The work was carried out on a commercial farm in the northeast of the Santa Fe province, Argentina. 54,000 bro...

Animal welfare Environmental conditions Commercial production Bienestar animal Condiciones ambientales Producción comercial The aim of this work was to evaluate the effect of decreasing stocking density and shed area on footpad dermatitis, hock burn, and ventral feathers cleanliness of broilers reared in winter. The work was carried out on a commercial farm in the northeast of the Santa Fe province, Argentina. 54,000 broilers were housed in sex-mixed batches, in two darkened sheds, divided into three zones: Panels, Intermediate and Extractors. Two stocking densities were evaluated: 14 and 12 chickens/m2, standard and reduced, respectively. At 41 days feet and hock lesions and cleanliness of ventral feathers was assessed in 120 chickens per area. Significant differences were registered for footpad lesions in Extractors (p = 0.0006), Intermediate (p = 0.0002) and Panels (p <0.0001) zones, with predominance of lesions 1 and 2 in Intermediate and Panels zones with standard density. Non-significant differences were observed for hock lesions in Extractors (p = 0.111) a response not seen in Intermediate (p = 0.024) and Panels (p <0.0001) zones, with more type 2 lesions in both zones under standard density. Feather cleanliness showed significant differences in Extractors (p = 0.014) Intermediate (p = 0.01) and Panels (p <0.0001), with a higher proportion of type 3 plumage dirt with standard density. Welfare indicators behaviour showed the favourable change achieved by reducing stocking density in broilers production. El objetivo de este trabajo fue evaluar el efecto de la disminución de la densidad de alojamiento y de la zona del galpón sobre lesiones en almohadilla plantar, tarso y suciedad de plumas ventrales de pollos de engorde criados en invierno. El trabajo se realizó en una granja comercial en el noreste de la provincia de Santa Fe, Argentina. Se alojaron 54.000 pollos de engorde en lotes mixtos, en dos galpones oscurecidos, divididos en tres zonas: Paneles, Intermedia y Extractores. Se evaluaron dos densidades de alojamiento: 14 y 12 pollos/m2, estándar y reducida, respectivamente. A los 41 días se valoró la presencia de lesiones y suciedad del plumaje ventral en 120 pollos por zona. Las lesiones de almohadilla plantar registraron diferencias significativas en Extractores (p= 0,0006), Intermedia (p= 0,0002) y Paneles (p< 0,0001), con mayoría de lesiones 1 y 2 en Intermedia y Paneles con densidad estándar. Las lesiones de tarso no fueron significativas en Extractores (p= 0,1107), sí en Intermedia (p= 0,0235) y Paneles (p< 0,0001), ambas, con más lesiones tipo 2 en la densidad estándar. En suciedad de plumas hubo diferencias significativas en Extractores (p= 0,014), Intermedia (p= 0,01) y Paneles (p< 0,0001), con mayor proporción de plumaje tipo 3 en la densidad estándar. Las variables evaluadas dan cuenta del cambio favorable en la situación de bienestar alcanzada mediante la reducción de la densidad de alojamiento en pollos de engorde.
