The objective of this study was to evaluate the animal welfare of chickens for meat raised in two types of sheds, using four animal-based indicators with an individual methodology. The trial was carried out in the northeastern region of Santa Fe province (Argentina) over two summer production cycles. Eight closed sheds with forced ventilation were tested, four blackout-type (Dark) sheds and four tunnel-type (Light) sheds, distributed across four grow-out farms. Between days 35 and 42 of the production cycle, 25 male and female Cobb 500® hybrid chickens, in five points of every sheds, were examined. The following welfare indicators were assessed: feather soiling (FS), footpad lesions (FPL), tarsal burn (TB) and gait (G), with severity scored according to the Welfare Quality® methodology. Statistically significant differences were observed between housing types across all four variables using a chi-square homogeneity test. In FS (p = 0.0103) and FPL (p<0.0001 higher proportions of feather soiling and footpad lesions were observed in the Light sheds, while in TB (p=0.0002) and G (p<0.0001), a higher percentage of affected chickens was found in the Dark sheds. The results indicate that, while the facilities provide adequate conditions for rearing, precise adjustments are still needed to optimize the interactions between environmental components and enhance animal welfare. La industria del pollo para carne constituye una de las principales fuentes de proteína animal y requiere de instalaciones y equipamiento de alto nivel tecnológico. El objetivo del presente ensayo fue evaluar el bienestar animal de pollos para carne en dos tipos de galpones, mediante el empleo de cuatro indicadores basados sobre los animales con una metodología individual. El ensayo fue realizado en el noreste de la provincia de Santa Fe (Argentina) en dos ciclos productivos de verano. Fueron testeados ocho galpones cerrados de ventilación forzada, cuatro de tipo blackout (Oscuros) y cuatro de tipo túnel (Claros), pertenecientes a cuatro granjas de engorde. Entre los días 35 y 42 del ciclo fueron capturados 25 pollos machos y hembras del híbrido Cobb 500(R) en cada uno de cinco puntos del galpón, en los que se observó: suciedad de plumas (SP), lesiones de almohadilla plantar (LAP), quemadura de tarso (QT) y marcha (M), con la escala de gravedad establecida por la metodología de Welfare Quality®. Fueron observadas diferencias estadísticamente significativas entre los tipos de galpones en las cuatro variables mediante una prueba chi-cuadrado de homogeneidad. En SP (p = 0,0103) y LAP (p<0,0001) estas diferencias mostraron mayor proporción de suciedad de plumas y afección de las almohadillas plantares en los galpones Claros. En en el caso de QT (p = 0,0002) y M (p<0,0001) fue observado un mayor porcentaje de pollos afectados en los galpones Oscuros. Los resultados muestran que las instalaciones utilizadas con el fin de proporcionar condiciones de crianza adecuadas, aún requieren de ajustes precisos de las interacciones entre los componentes del medio ambiente en el que se desenvuelven para mejorar el bienestar animal.
