Automatic early warning of tail biting in pigs: 3D cameras can detect lowered tail posture before an outbreak. [PDF]

PLoS ONE, 2018
Tail biting is a major welfare and economic problem for indoor pig producers worldwide. Low tail posture is an early warning sign which could reduce tail biting unpredictability.

Local Irreducibility of Tail-Biting Trellises [PDF]

IEEE Transactions on Information Theory, 2013
This paper investigates tail-biting trellis realizations for linear block codes. Intrinsic trellis properties are used to characterize irreducibility on given intervals of the time axis. It proves beneficial to always consider the trellis and its dual simultaneously.

Influence of tail biting on weight gain, lesions and condemnations at slaughter of finishing pigs

Pesquisa Veterinária Brasileira, 2012
The present study assessed the association of tail-biting lesions in finishing pigs with weight gain, occurrence of locomotion or respiratory disorders and abscesses during finishing period, and carcass condemnation at slaughter.

Jejunal morphology and blood metabolites in tail biting, victim and control pigs

Animal, 2013
Tail biting has several identified feeding-related risk factors. Tail biters are often said to be lighter and thinner than other pigs in the pen, possibly because of nutrition-related problems such as reduced feed intake or inability to use nutrients ...

Tail biting in pigs: blood serotonin and fearfulness as pieces of the puzzle? [PDF]

PLoS ONE, 2014
Tail biting in pigs is a widespread problem in intensive pig farming. The tendency to develop this damaging behaviour has been suggested to relate to serotonergic functioning and personality characteristics of pigs. We investigated whether tail biting in

Activity and synchrony patterns obtained by a tracking-by-detection algorithm as potential predictors of tail biting at pen and individual level in pigs

Animal
Tail biting is a major welfare concern in pigs. Timely interventions may help to reduce its spread in an outbreak. However, tail biting is usually detected only at an injury stage. Therefore, early indicators are needed to predict outbreaks.

Changes in tail posture detected by a 3D machine vision system are associated with injury from damaging behaviours and ill health on commercial pig farms.

PLoS ONE, 2021
To establish whether pig tail posture is affected by injuries and ill health, a machine vision system using 3D cameras to measure tail angle was used. Camera data from 1692 pigs in 41 production batches of 42.4 (±16.6) days in length over 17 months at ...

Irish pig farmer’s perceptions and experiences of tail and ear biting

Porcine Health Management, 2019
Abnormal behaviours such as ear and tail biting of pigs is of significant welfare and economic concern. Currently, pig welfare legislation is under renewed focus by the EU commission and is likely to be enforced more thoroughly. The legislation prohibits
