Alternative flooring designs in broiler housing have been the subject of intensive research. Research comparing different floor types with a focus on animal-based welfare indicators might be of special interest to meet the animal's needs. This case–control study investigated the effect of a partially perforated vs. a littered flooring system on health- and behavior-based welfare indicators of fast-growing Ross 308 broilers. Furthermore, production performance was assessed. The experimental barn was partially (50%) equipped with a perforated floor directly underneath the feeders and water lines accessible by perforated ramps. Conventional wood shavings were used in the control barn, as usual in practice. There were 4 fattening periods (repetitions) of 31 to 32 D performed with 500 animals per barn (final density of 39 kg m −2 ). Beside the flooring system, management conditions were identical. Health- and behavior-based welfare indicators were assessed weekly. Production performance indicators were measured continuously during animal control. During the avoidance distance test, animals were less fearful on day 21 ( P = 0.010) and tended to be less fearful on day 28 ( P = 0.083) in the barn with the partially perforated flooring system compared to the littered control barn. More animals around the novel object were also assessed in the barn with the partially perforated flooring system during the novel object test on day 1 ( P < 0.001) and a tendency was found on day 28 ( P = 0.064). Results showed that the partially perforated flooring system had a positive influence on foot pad dermatitis from day 14 (all P ≤ 0.007) and hock burn on day 28 ( P < 0.001). With regard to the production performance, animals showed no differences in final body weight for both floor types. In this study, the partially perforated flooring system had a positive effect on animal health and behavior as indicated by welfare indicators without a reduction in production performance.

“…Los resultados de la producción física por metro cuadrado son superiores cuando se alojan 17 pollos/m 2 , lo que sugiere que, cuando no se consideran las variables relacionadas con el bienestar animal, se alcanza mejor rentabilidad con el aumento de la densidad. Aunque se acepta que el mayor contenido de humedad de la cama es la causa más importante de la podo-dermatitis, la relación entre la densidad de alojamiento, época del año y lesiones es poco clara 16 .…”

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.

“…In this system, the management of bedding material is very critical to provide good litter quality. However, it is challenging to keep litter dry and in good condition in litter floors due to drinker type, bedding material, and high stocking density [ 8 , 9 ].…”

Objective: This experiment was conducted to assess the effects of the housing system on the welfare and growth performance of the Muscovy duck. Materials and methods: A total number of 48 Muscovy duck aged 3-week old were divided randomly into two groups (24 duck on each): deep litter system and cage system. Each group was subdivided into three replicates (8 birds on each) were identified with wing rings. Results: The study showed that feeding and drinking behaviors significantly increased ( p < 0.05) in duck reared at the cage system. While there was no noticeable effect on lying and feather pecking, duck raised in the deep litter had better growth performance with a substantial difference, which achieve a higher feed conversion rate with lower feed efficiency. Physical conditions were significantly better at cage management. The level of stress indicating hormones indicating free Thyroxin was increased with the cage. Therefore, the litter system improves duck welfare and their performance. Conclusion: It is concluded that the duck managed under the litter system has more opportunities that facilitate the expression of more natural behavior, and thus improve their health and performance, as a result of improved feed conversion rate and feed efficiency.
