Alternative Solutions to Beak trimming in Layer Hens to Reduce Feather pecking and Improve Welfare

چکیده

Feather pecking (FP) is one of the most significant welfare and economic problems in the egg production industry (Wysocki et al., 2010). For many years the solution to this problem has been beak trimming, which typically involves removing approximately 30% of the upper and lower mandibles with an electrically heated blade (Dennis & Cheng, 2010). However, this practice is now under scrutiny due to growing concerns for animal welfare. The procedure causes acute pain and distress in the bird and there is also evidence to suggest chronic pain due to the formation of neuromas (Cheng, 2006). Furthermore, removing part of the beak mechanically impairs the birds’ ability to express natural behaviours such as foraging. Therefore, it is reasonable to suggest that the practice of beak trimming is simply substituting one welfare issue with another. This essay endeavours to explore the reasons behind FP in layer hens and how these may underpin the potential of alternative solutions to this problem.

Infrared beak treatment method compared with conventional hot-blade trimming in laying hens.

Infrared lasers have been widely used for noninvasive surgical applications in human medicine, and their results are reliable, predictable, and reproducible. Infrared lasers have recently been designed for the express purpose of providing a less painful, more precise beak-trimming method compared with conventional beak trimming. This study was designed to examine the potential of the infrared (...

The effects of environmental enrichment and beak-trimming during the rearing period on subsequent feather damage due to feather-pecking in laying hens.

This experiment investigated effects of environmental enrichment and beak-trimming during the rearing period on behavior in rearing and plumage damage later in life. Treatments were applied in a 2 × 2 factorial arrangement. Half of the birds were beak-trimmed at 1 d of age using an infra-red laser. A follow-up light-trim was performed at 11 wk of age with a hot blade. Environmental enrichment c...

Modelling of feather pecking behavior in beak-trimmed and non-beak-trimmed crossbred laying hens: variance component and trait-based approach.

Because of a ban on the use of beak trimming in some European countries, feather pecking is becoming a substantial problem in the layer industry, both from animal welfare and economic points of view. The feather condition score (FCS) as a measure of feather damage has been shown to be closely related to feather pecking behavior in laying hens housed in groups. To obtain a better understanding o...

Welfare Consequences of Omitting Beak Trimming in Barn Layers

Beak trimming is used worldwide as a method of reducing the damage to feathers and skin caused by injurious pecking in laying hens. However, beak trimming also causes some welfare issues as trimming the beak results in pain and sensory loss. Due to this dilemma, there is an ongoing discussion in several European countries about whether to ban beak trimming. In this study, we investigated the we...
