Tail-directed behaviour in pigs – relation to tail posture and tail lesion
Sign Up to like & getrecommendations! Published in 2020 at "Applied Animal Behaviour Science"
DOI: 10.1016/j.applanim.2020.105151
Abstract: Abstract Tail-biting in pigs affects the health and welfare of the animals. Different indicators, such as the tail posture, can be used to detect tail-biting at an early stage. The aim of this study was… read more here.

DOI: 10.1016/j.applanim.2021.105385
Abstract: Abstract Tail biting in pigs is a damaging behaviour and remains an economic and welfare problem in modern pig production. Although tail biting has been extensively investigated, little is known about the behaviour in piglets.… read more here.

DOI: 10.1016/j.livsci.2019.103879
Abstract: Abstract Tail biting in pigs with undocked tail often occurs in a high frequency and then leads to significant injuries. In previous investigations tail lesions were recorded. In direct visual observations of 98 weaner pigs… read more here.

DOI: 10.1016/j.livsci.2020.104136
Abstract: Abstract Videos of pigs were analysed using an optical flow algorithm to measure group movement in the four days leading up to and including an outbreak of tail-biting. 8 pens in which tail-biting occurred (Outbreak)… read more here.

DOI: 10.1049/el.2019.3372
Abstract: The maximum a posteriori (MAP) detection of a continuous phase modulation (CPM) signal deploys the Bahl-Cocke-Jelinek-Raviv (BCJR) algorithm that utilises the trellis structure of the CPM signal. For optimal results the start as well as… read more here.

DOI: 10.1109/twc.2021.3071379
Abstract: This paper introduces a low complexity and optimum decoding algorithm for tail-biting codes. The algorithm, called Selective Initialization Viterbi Algorithm (SIVA), performs the Viterbi algorithm (VA) iteratively and assigns at each iteration the initial costs… read more here.

The Evidence for a Causal Link Between Disease and Damaging Behavior in Pigs
Sign Up to like & getrecommendations! Published in 2021 at "Frontiers in Veterinary Science"
DOI: 10.3389/fvets.2021.771682
Abstract: Damaging behaviors (DB) such as tail and ear biting are prevalent in pig production and reduce welfare and performance. Anecdotal reports suggest that health challenges increase the risk of tail-biting. The prevalence of tail damage… read more here.

DOI: 10.3389/fvets.2022.1099347
Abstract: Automated monitoring of pigs for timely detection of changes in behavior and the onset of tail biting might enable farmers to take immediate management actions, and thus decrease health and welfare issues on-farm. Our goal… read more here.
