Summary
A novel laser enrichment device successfully motivated broiler chickens to increase physical activity and feeding behaviors. This environmental enrichment did not negatively affect their walking ability, offering a promising welfare improvement.
Area of Science:
- Animal Science
- Animal Welfare
- Behavioral Science
Background:
- Modern broiler chickens exhibit rapid growth and high breast meat yield, leading to a top-heavy physique, leg issues, and reduced activity.
- These physical traits can negatively impact broiler welfare as they approach market weight.
Purpose of the Study:
- To investigate the efficacy of a novel laser enrichment device in motivating broiler chickens to increase physical activity and feeding.
- To assess the impact of laser enrichment on broiler behavior, including activity levels, feeding latency, and distance walked.
Main Methods:
- 1,200 Ross 308 broiler chickens were divided into two groups: 600 exposed to a laser enrichment device (LASER) and 600 controls.
- The laser device projected moving red dots on the floor for short periods, four times daily.
- Broiler activity, time budget, feeding behavior, gait, and response to human approach were recorded and analyzed over six weeks.
Main Results:
- Broilers in the LASER group showed significantly increased activity levels and distance walked during laser periods compared to controls.
- LASER birds spent more time at the feeder, indicating enhanced feeding motivation.
- No negative impact on walking ability or gait score was observed in the laser-treated group.
Conclusions:
- The laser enrichment device effectively stimulated physical activity and feeding behaviors in broiler chickens.
- This innovative environmental enrichment shows potential for improving broiler welfare by promoting natural behaviors without compromising mobility.
