“…This demonstrates poor treatment of the beak and regrowth problems. This is in line with field results [6,14,47], also with infra-red beak trimming. It therefore seems that the technique still needs to be better controlled and adapted to the anatomy of the beak.…”

“…Injurious pecking is not a new problem: a large amount of research has been carried out to determine the factors influencing IP. However, it is still difficult to systematically prevent and treat because it is a multifactorial problem with a wide range of possible risk factors including genetics, stocking density, group size, floor type, feed, light (intensity, wave length) and others environmental factors [4,[10][11][12][13][14][15][16].…”

“…Generally, producers try to match the type of rearing facility with the type of layer facility, especially for aviary systems, but this is not always possible. In France, one of the leading egg producer in the EU with 1 million tons eggs in 2019 [2], laying hens housed in cages are in 60% of cases housed in barn systems during the rearing period, without any enrichment except litter (personal data-survey used in [14]). Rearing in a relatively spacious environment with access to substrate and other enrichments, followed by transfer to a restrictive environment without any substrate, or with a relatively poor substrate, may cause frustration inducing high reactivity and IP [20].…”

Beak trimming in laying hens limits the negative consequences of injurious pecking, but could be prohibited by future regulations. This study assessed a combination of management strategies during the rearing period (objects, perches, music, human presence) and laying period (scratching mats, objects, feed fiber supplementation) to raise non-beak-trimmed animals. The welfare and laying performances of beak-trimmed (T) and non-beak-trimmed (NT) ISA Brown birds were compared between groups with (E) or without (NE) these strategies, with or without fiber supplementation in the diet during laying period. Fiber supplementation did not provide any benefit on pecking-related problems. In comparison with NT-NE birds, NT-E birds had lower mortality, were less fearful of a novel object, and had a better feather cover, without a negative impact on productivity (same laying rate and egg quality). Although this study showed advantages of beak trimming (T birds had higher body weights, laying rates and lower hen mortality than NT birds), it highlighted related problems (increasing pullet mortality, decreasing early weights and increasing beak defects). This study proposes practical solutions to limit the consequences of injurious pecking in non-beak-trimmed animals.

“…Although FP can be seen in other avian species such as broiler chickens, turkeys, ducks, pheasants, ostriches, and parrots, it is in laying hens that FP has been the most extensively studied (Dixon 2008). The complexity of FP lies in its multifactoriality (Coton et al 2019). Jung and Knierim (2018), in a recent review of experimental and epidemiological studies, found at least 62 factors that can significantly affect the risk of a flock to develop FP or plumage damage.…”

A recent definition of animal welfare states that "the welfare of an animal is its positive mental and physical state related to the fulfilment of its physiological and behavioural needs in addition to its expectations. This state can vary depending on the animal's perception of a given situation'. This definition confirms the importance of taking the individual animal perspective (i.e. its cognition) into consideration, in order to properly assess its welfare. Cognitive abilities of domestic chickens have been extensively studied in recent years, but few of these studies focussed on the relationship between chicken cognition and welfare issues commonly found in chicken production systems. Considering the chickens' cognitive abilities offers new and different perspectives on the welfare problems faced by chicken production. Combined with applied research, cognitive studies can generate impactful and sciencebased strategies to solve these problems better. In this short nonsystematic review, we focus on cognitive research aimed at understanding three widespread welfare issues in poultry production: uneven range use in free-range broiler chickens and laying hens, feather pecking in laying hens, and the unfulfilled behavioural and physiological needs of broiler breeders. Knowledge of chicken cognitive abilities is critical to ameliorate chickens' rearing conditions and develop systems and practices that are more respectful of animal welfare.

“…Thus, bad feather growth reduces the net profitability of poultry production (Lopez-Coello, 2003;Zeng et al, 2015). However, in the commercial production of poultry, plumage defects often occur, such as feather pecking, molting, and inadequate body coverage (Bajpai et al, 2016;Coton et al, 2019). Therefore, investigating the feather morphogenesis and development, signal transduction pathways, and effective nutrient interventions of poultry is of great economic significance.…”

The normal growth and regeneration of feathers is important for improving the welfare and economic value of poultry. Feather follicle stem cells are the basis for driving feather development and are regulated by various molecular signaling pathways in the feather follicle microenvironment. To date, the roles of the Wnt, Bone Morphogenetic Protein (BMP), Notch, and Sonic Hedgehog (SHH) signaling pathways in the regulation of feather growth and regeneration are among the best understood. While these pathways regulate feather morphogenesis in different stages, their dysregulation results in a low feather growth rate, poor quality of plumage, and depilation. Additionally, exogenous nutrient intervention can affect the feather follicle cycle, promote the formation of the feather shaft and feather branches, preventing plumage abnormalities. This review focuses on our understanding of the signaling pathways involved in the transcriptional control of feather morphogenesis and explores the impact of nutritional factors on feather growth and regeneration in poultry. This work may help to develop novel mechanisms by which follicle stem cells can be manipulated to produce superior plumage that enhances poultry carcass quality.
