Dogs distinguish human intentional and unintentional action

Britta Schünemann, Judith Keller, Hannes Rakoczy, Tanya Behne, Juliane Bräuer

Published in 2021

Scientific article on whether dogs are able to distinguish between situations where a human intentionally withholds a reward and those where the lack of reward is unintentional, resulting either from a mistake or a physical obstacle that prevents the reward being given. The results show that dogs clearly distinguish between intentional and unintentional behaviour.

Determination of static space requirements for finishing bulls based on image analysis

N. Volkmann, J. Stracke, S.L. Rauterberg, B. Spindler, N. Kemper

Published in 2021

Scientific paper providing information on the space requirements of finishing bulls to ensure their welfare. It focuses on the space occupied when motionless in the standing and lying positions and concludes that further studies are needed to take into account the space requirements of bulls to allow movement and social interactions.

Network analysis of tail-biting in pigs - indirect effect on tail posture

Thore Wilder, Joachim Krieter Nicole Kemper, Kathrin Büttner

Published in 2021

Scientific paper examining whether the tail position of pigs in a pen can be a predictive indicator for the occurrence of tail biting, taking into account the social structure of the group of penned pigs.

Behavior and Welfare of Undocked Heavy Pigs Raised in Buildings with Different Ventilation Systems

Marika Vitali, Enrica Santolini, Marco Bovo, Patrizia Tassinari, Daniele Torreggiani,Paolo Trevisi

Published in 2021

Scientific paper comparing the influence of two ventilation systems (natural and mechanical) on the behaviour and welfare of fattening pigs. It concludes that the mechanical system is associated with a more positive emotional state in the pigs, but that in both systems high temperatures are associated with heat stress, and that the welfare state of the animals decreases during the last phases of fattening.

The Application of Cameras in Precision Pig Farming: An Overview for Swine-Keeping Professionals

Elanchezhian Arulmozhi, Anil Bhujel, Byeong-Eun Moon, Hyeon-Tae Kim

Published in 2021

A scientific review of the state of the art of 3D imaging systems and 2D cameras as an efficient means to identify pig behaviour. It describes automated methods for the monitoring and study of feeding, watering, lying, locomotion, aggression and reproductive behaviour in pigs.

Horse Behavior towards Familiar and Unfamiliar Humans: Implications for Equine-Assisted Services

Lauren Brubaker, Katy Schroeder, Dawn Sherwood, Daniel Stroud, Monique A. R. Udell

Published in 2021

Scientific paper describing research to discover appropriate criteria to predict the potential suitability of a horse for animal-assisted services. It shows that sociability indicators and most temperament indicators of experienced AAS horses do not differ from those of novice AAS horses. However, during brushing, novice horses showed more affiliative behaviour towards their handler than experienced ones.

Dairy Cows Activity under Heat Stress: A Case Study in Spain

Adrián Ramón-Moragues, Patricia Carulla, Carlos Mínguez, Arantxa Villagrá, Fernando Estellés

Published in 2021

Scientific paper on work to assess the effects of heat stress on the behaviour of dairy cows using activity sensors to record 6 different behaviours, ambient temperature and humidity. It shows that raised temperatures and a higher heat index lead to an increase in general activity, changes in feeding habits and a decrease in rumination and resting behaviours, all of which are detrimental to animal welfare.

Give Them a Toy or Increase Time out of Kennel at Lawn Areas: What Is the Influence of These Interventions on Police Dogs' Welfare?

Letícia Bicudo Nogueira, Rupert Palme, Olívia Mendonça-Furtado

Published in 2021

Scientific paper showing that the provision of environmental enrichment for kenneled police dogs has a stress-reducing effect (reduced levels of cortisol metabolites in the stool) and that access to a grassed area reduces the frequency of stereotypic behaviours in dogs with strong stereotypical tendencies.

Lying behaviour of housed and outdoor-managed pregnant sheep

Manod Williams, Chelsea N. Davis, Dewi Llyr Jones, Emma S. Davies, Penelope Vasina, David Cutress, Michael T. Rose, Rhys Aled Jones, Hefin Wyn Williams

Published in 2021

A scientific paper investigating the mobility and lying behaviours of ewes housed indoors or reared on grass using video recordings. It shows that 1 min video samples can reliably predict ewe lying behaviours and that there are links between breeding characteristics (ewe age, single or double gestation, body condition index, lambing ease etc) and measured lying behaviours (average daily lying time, average duration of lying episodes etc).
