More tail lesions among undocked than tail docked pigs in a conventional herd

open access: yesAnimal, 2017
The vast majority of piglets reared in the European Union (EU) and worldwide is tail docked to reduce the risk of being tail bitten, even though EU animal welfare legislation bans routine tail docking.

Tail posture and motion in relation to natural behaviour in juvenile and adult pigs

open access: yesAnimal, 2022
The tail of pigs has been suggested as a welfare indicator as it can provide insight into a pig’s behavioural and emotional states. Tail posture and motion have so far mainly been studied in the context of tail biting behaviour. The aim of this study was

Tail docking in pigs: a review on its short- and long-term consequences and effectiveness in preventing tail biting

open access: yesItalian Journal of Animal Science, 2014
In spite of European legislation attempting to limit this practice, tail docking is nowadays the only preventive measure against tail biting which is widely adopted by farmers. Docking consists in amputating, usually without anaesthesia or analgesia, the

Scientific Opinion concerning a Multifactorial approach on the use of animal and non-animal-based measures to assess the welfare of pigs [PDF]

open access: yesEFSA Journal, 2014
Pigs have a need for manipulable materials to satisfy a range of behavioural needs, which can be different in different classes of pig. When these needs are not met, a range of adverse welfare consequences result, one of these being an increased risk for

Exact Free Distance and Trapping Set Growth Rates for LDPC Convolutional Codes

open access: yes, 2011
Ensembles of (J,K)-regular low-density parity-check convolutional (LDPCC) codes are known to be asymptotically good, in the sense that the minimum free distance grows linearly with the constraint length.

Turning the gaze to maize: The effects of maize kernels in straw as enrichment on exploration in pigs

open access: yesBerliner und Münchener Tierärztliche Wochenschrift, 2020
Tail biting is one of the biggest problems in pig production systems that causes animal welfare and economic problems. Therefore, tail docking is a widely used intervention to reduce tail biting.

Iterative min-sum decoding of tail-biting codes [PDF]

open access: yes, 1998
By invoking a form of the Perron-Frobenius theorem for the “min-sum” semi-ring, we obtain a union bound on the performance of iterative decoding of tail-biting codes.

Spatially Coupled LDPC Codes Constructed from Protographs

open access: yes, 2014
In this paper, we construct protograph-based spatially coupled low-density parity-check (SC-LDPC) codes by coupling together a series of L disjoint, or uncoupled, LDPC code Tanner graphs into a single coupled chain.

Changes in activity and object manipulation before tail damage in finisher pigs as an early detector of tail biting

open access: yesAnimal, 2019
Tail damage within the production of finisher pigs is an animal welfare problem. Recent research suggests that removal of known risk factors may not be enough to eliminate tail biting, especially in undocked pigs, thus a different strategy is worth ...

Feedback Communication Systems with Limitations on Incremental Redundancy [PDF]

open access: yes, 2013
This paper explores feedback systems using incremental redundancy (IR) with noiseless transmitter confirmation (NTC). For IR-NTC systems based on {\em finite-length} codes (with blocklength $N$) and decoding attempts only at {\em certain specified ...
