Historically, animal welfare has been defined by the absence of negative states such as disease, hunger and thirst. However, a shift in science led to understanding that good cannot be achieved without experience positive states. Unequivocally, housing environment significant impacts on welfare. This review summarises how cage cage-free systems impact some key issues for layer hens: musculoskeletal health, severe feather pecking, behavioural expression. Welfare is currently highly variable,...
Severe feather-pecking (SFP), a particularly injurious behaviour in laying hens (Gallus gallus domesticus), is thought to be negatively correlated with range use free-range systems. In turn, inversely associated fearfulness, where fearful birds may less likely venture outside. However, very few experiments have investigated the proposed association between and fearfulness. This experiment associations (time spent outside), plumage damage, BW. Two pens of 50 ISA Brown (n=100) were fitted...
This experiment investigated effects of environmental enrichment and beak-trimming during the rearing period on behavior in plumage damage later life. Treatments were applied a 2 × factorial arrangement. Half birds beak-trimmed at 1 d age using an infra-red laser. A follow-up light-trim was performed 11 wk with hot blade. Environmental consisted pecking strings, whole oats litter, greater litter depth. Sixteen pens 50 ISA Brown laying hens used. Four pullets selected from each pen as focal...
Several countries and regions have regulations in place to provide standards for the welfare of production animals, which implications breeding, management trade. In chicken egg industry, impacts this are not well understood. past decades, free-range systems were widely used local breeds poultry industry China, but their use has gradually declined due lower competitiveness compared commercial cage systems. However, practices hens raising increased again over decade, as consumer...
Asia is responsible for ~60% of global egg production. As in most the world, nearly all egg-laying hens are housed cages. While there growing demand cage-free eggs many regions challenges have been reported when transitioning to these systems, which may affect willingness producers transition. The aim this research was investigate views Asian on feasibility systems and what they perceive be main proposed solutions adopting systems. A total 224 (165 cage producers) completed questionnaires...
Abstract Conditions in early life play profound and long-lasting effects on the welfare adaptability to stress of chickens. This study aimed explore hypothesis that provision environmental complexity improves birds’ adaptive plasticity ability cope with a challenge later life. It also tried investigate effect gut-brain axis by measuring behavior, hormone, gene expression, gut microbiota. One-day-old chicks were split into 3 groups: (1) barren environment (without enrichment items) group (BG,...
As a species of waterfowl, ducks rely on access to water facilitate feeding behaviors. Further, wet preening behavior in relies and is key for duck welfare. Traditionally, Chinese farms provide not only free drinking the house but also an open pool outside house. However, recent restrictions prohibit use raising some areas China. Little known about effects providing welfare, particular, development preen gland The secretes oil which crucial maintaining plumage conditions. A total one hundred...
Severe feather-pecking (SFP) persists as a highly prevalent and detrimental behavioural problem in laying hens (Gallus gallus domesticus) worldwide. The present experiment investigated the association between feather-eating plumage damage, consequence of SFP, groups free-range, ISA Brown hens. Single feathers were placed on floor home pens. Feathers sourced from seven different birds. A total 50 birds six pens with extensive damage compared control little at 41 to 43 weeks age (n=12 pens,...
“Demonstration farms” can disseminate knowledge on farming practices and help to promote animal welfare. When on-farm visits are impractical, remote demonstrations a feasible alternative. This study used videos of higher welfare beef, fish free-range egg farms in China. It aimed determine whether the affected attitudes intentions toward such useful training tools. Participants indicated high acceptability demonstration farm for learning about their industry needs animals. Videos shifted...
Abstract There is a trend towards the adoption of cage-free housing systems in egg industry across Asia. While can hold significant animal welfare advantages over cages, there also be challenges managing these systems. This exploratory study aimed to investigate perspectives producers on main and proposed solutions associated with China, Indonesia, Thailand, Japan, Malaysia, Philippines. Cage-free found disease prevention maintaining healthy profit margin more difficult than from cage farms,...
