Abstract: The present study aimed to assess the influence of adding straw bales, step platforms, and laser projectors as environmental enrichment resources on the behaviour and welfare indicators of broiler chickens (Gallus gallus domesticus). A sample of 4,000 day-old male Cobb® 500 birds was used. The experimental treatments consisted of No Environmental Enrichment (NEE)—similar to a conventional environment; and Environmental Enrichment (EE)—environment enriched with straw bales, step platforms, and laser projectors,… Show more

“…Los pollos permanecieron poco tiempo levantados durante todo el experimento, sin embargo, no fue posible relacionar este comportamiento con la presencia de miopatías. Lourenço da Silva et al (2021) observaron que el comportamiento de permanecer echados fue el más frecuente en pollos de engorde sanos, sin estrés de calor y sin enriquecimiento ambiental. La conformación corporal de los pollos modernos puede explicar también el bajo nivel de actividad de los pollos, debido a que el crecimiento rápido de la pechuga mueve el centro de gravedad hacia delante y el tamaño relativamente corto de las patas, en relación con el peso y tamaño del cuerpo, dificulta el movimiento de las aves (Gentle, 2011).…”

“…Locomotor disorders can to some extent be prevented by increasing animal activity, as locomotion can positively impact skeletal development [17,18]. Positive activity such as exploratory behavior and locomotion can be stimulated through environmental enrichments, such as straw or hay bales, platforms, and moving laser lights [17][18][19][20].…”

“…Environmental enrichments increase the complexity of broiler chicken environments and enhance the expression of natural behaviors, i.e., foraging, perching, and playing [19,21]. Foraging is a highly motivated behavior associated with exploration and the appetitive phase of feeding behavior.…”

“…Black soldier fly (BSF) and yellow mealworm (YM) live larvae provision has recently been proposed as promising food environmental enrichment to promote welfare in broiler chickens, with increased activity and foraging behaviour (as a result of the search for larvae on the ground), and reduced occurrence of hock burns and lameness (as a result of the increased activity) being observed in the administered birds ( Pichova et al, 2016 ; Ipema et al, 2020 ). Welfare assessment in broiler chickens is usually object of a multiperspective approach, as heterogeneous parameters (such as plumage status, hock burns and footpad dermatitis, lameness, behavioural patterns, and excreta corticosterone) are commonly evaluated ( Weimer et al, 2018 ; Giersberg et al, 2021 ; Iannetti et al, 2021 ; Lourenço da Silva et al, 2021 ). Despite beneficial live insect larvae-related effects on bird behaviour and feathering scores having recently been highlighted in either turkeys ( Veldkamp and van Niekerk, 2019 ) or laying hens ( Star et al, 2020 ; Tahamtani et al, 2021 ), data about modulation of plumage status and excreta corticosterone in broiler chickens reared in live insect larvae-enriched environment are still missing.…”
