Summary

Here is a summary of the research study for a health-conscious reader. ### **Plain-Language Summary** This scientific review assessed the well-being of farmed turkeys and concluded that many common industry practices cause significant stress and health problems. The researchers recommend major improvements, including giving turkeys more space, providing mentally stimulating environments, and shifting breeding priorities from rapid growth to better overall health. ### **Key Findings** * **Environment is Crucial:** Crowded, barren conditions with damp flooring contribute to injuries like footpad dermatitis and breast blisters, as well as stress-related behaviors. * **Mutilations Are Avoidable:** Painful procedures like beak and toe trimming are typically done to manage aggression in cramped spaces but would be unnecessary if turkeys were given adequate space and enrichment. * **Breeding for Size Harms Health:** Genetic selection focused heavily on rapid weight gain has led to widespread leg weakness and mobility issues. The study recommends prioritizing skeletal health in breeding programs. * **Feed Restriction is a Major Stressor:** Severely restricting food for breeding turkeys to control their weight is a significant welfare concern and is recommended to be discontinued. ### **Practical Takeaways for Nutrition and Longevity** The chronic stress and poor health experienced by animals can impact the quality of the final meat product. For consumers, this means that turkey raised in higher-welfare conditions—with more space, outdoor access, and a focus on natural behaviors—is likely to come from a healthier animal. When possible, look for certifications that guarantee higher welfare standards, as these address the key issues identified in this report. ### **Study Limitations** This document is a scientific opinion that synthesizes existing research to form recommendations. It is a comprehensive review rather than a single new experimental study.

Abstract

This Scientific Opinion assesses the welfare of turkeys of all ages (<i>Meleagris gallopavo gallopavo</i>) on farm in relation to the type and condition of the litter, type and availability of enrichment (including covered veranda and outdoor range), space allowance, concentrations of ammonia and carbon dioxide, effective environmental temperature, group size, nest conditions, lighting conditions and hatchery conditions, by using 19 welfare consequences and associated animal-based measures (ABMs) for their assessment. In addition, the risks posed by the practices of flock thinning and removal of hens, mutilations (i.e. beak trimming, desnooding and toe trimming), artificial insemination (including semen collection) and feed restriction are assessed, with the latter two practices only in turkey breeders. The welfare consequences of breeding is assessed. Recommendations to prevent and/or mitigate relevant welfare consequences in fattening and breeder turkeys include increasing space allowance compared to the currently provided space, avoiding feed and water deprivation of newly-hatched poults for more than 48 h, and providing enrichment such as elevated platforms, straw-bales and a covered veranda. It is recommended to maintain dry litter conditions, i.e. below a threshold of 35%-40% humidity. Beak trimming, desnooding and toe trimming as well as the associated welfare consequences can be avoided if the recommended housing and management practices are implemented, e.g. increasing space allowance and providing suitable enrichment. It is recommended to discontinue flock thinning and avoid quantitative feed restriction, the latter currently practised in breeder toms. Also, it is recommended to place more emphasis on leg health and less on weight gain in genetic selection. The selected ABMs to monitor relevant welfare consequences at the slaughterhouse are total mortality, plumage damage, carcass condemnation, wounds, breast blisters and footpad dermatitis.
