Poultry Catching and Handling at Slaughter: Welfare Standards

Poultry Catching and Handling: A Critical Welfare Point

The catching, crating, and transport of poultry to slaughter represents one of the highest-intensity welfare challenges in the poultry industry. The pre-slaughter period — from catching through to stunning at the slaughterhouse — exposes birds to handling by unfamiliar people, physical restraint, temperature extremes, and novel environments. Managing this period well is a critical welfare responsibility.

Catching and Manual Handling

Broiler chickens are typically caught by hand in darkened houses at 4-6 weeks of age. Catching involves grasping birds by their legs, and birds are typically carried multiple at a time. Manual catching causes: wing and leg fractures from rough handling, dislocation injuries, haematomas, stress, and fear responses. Catching-related injuries account for a significant proportion of injuries identified at post-mortem inspection.

Best practice for manual catching includes: minimum group sizes carried per catcher (4 birds maximum for broilers), carrying birds upright rather than inverted, gentle handling to minimise struggling and injury, trained and supervised catchers, and monitoring of injury rates as a welfare indicator.

Mechanical Catching Machines

Automated catching machines use rotating rubber fingers to scoop birds onto a conveyor and into crates. When correctly operated and maintained, mechanical catchers reduce injury rates compared to poor manual catching, but performance depends critically on machine condition, litter quality, stocking density, and operator supervision. Mis-caught birds can suffer severe injuries from machine components.

Module and Crate Systems

Birds are transported in plastic crates stacked on vehicles. Crate design affects welfare through: space allowance (minimum 160-200 cm²/kg for broilers under EU Regulation 1/2005), ventilation, and ease of loading and unloading without injury. Module systems (large multi-deck units loaded mechanically) can reduce manual handling compared to individual crate systems.

Thermal Stress During Transport

Poultry are highly vulnerable to thermal stress. Heat stress (above 32°C) causes mortality during transport; cold stress impairs welfare in winter. Transit mortality rates above 0.1% indicate thermal management failures. Journey times should be minimised; UK guidelines recommend maximum 12-hour journeys for chickens with feed withdrawal beginning a maximum of 12 hours before slaughter.

Pre-Slaughter Lairage

Time spent in lairage (waiting area at slaughterhouse) should be minimised — birds in crates experience restriction, social disruption, and thermal stress. Water deprivation during lairage increases stress. Processing scheduling should minimise lairage duration; maximum lairage times are specified in national welfare at slaughter legislation.

Welfare Monitoring

Dead on arrival (DOA) rates, carcase injury rates at post-mortem inspection, and wing fracture prevalence provide welfare feedback on catching and transport operations. Targets for broiler DOA rates are typically below 0.1%. Regular monitoring, investigation of exceedances, and feedback to catching crews improve outcomes.
