Cognition and the human-animal relationship: a review of the socio-cognitive skills of domestic mammals towards humans

Plotine Jardat, Léa Lansade

Published in 2021

Scientific review of 5 social-cognitive abilities possessed by domestic mammals in relation to humans: ability to distinguish between humans and recognise individuals;  perception of human emotions; interpretation of our attentional states and goals; use of referential communication (recognising human signals or sending signals to humans); and engagement in social learning with humans.

Reducing weaning stress: is pre-weaning socialisation a good strategy?

John Pluske

Published in 2021

Technical paper setting out the advantages and disadvantages of the two main techniques for socialising piglets housed indoors: one allows piglets to move freely between farrowing pens but not dams, and the other allows dams and piglets to interact freely. The outcomes of early socialisation are not only behavioural (more play, less aggression) but also physiological, with lower metabolic energy levels that could explain reductions in stress and aggression.

Does nutrient composition of feedstuffs affect the proportion of oral stereotypies and redirected behaviors among horse working groups?

Farah Hanis, Eric Lim Teik Chung, Mamat Hamidi Kamalludin, ZulkifliI drus

Published in 2021

Scientific paper demonstrating that ration composition and energy intake influence the incidence of oral stereotypies (especially empty chewing) and redirected behaviours (especially bedding consumption) in working horses (leisure, equestrian, patrol and endurance). Endurance horses are the most sensitive to ration composition.

Animal Signals, Music and Emotional Well-Being

Charles T. Snowdon

Published in 2021

Scientific review of the effect of music on the emotional state of animals. It recommends that available information on the sensory systems and behaviours of each species should be taken into account so that music can be selected in light of the desired emotional response from the animal, thereby improving its well-being.

The effect of pair housing on dairy calf health, performance, and behavior

Katarína Bučková, Radka Šárová, Ágnes Moravcsíková, Marek Špinka

Published in 2021

Scientific paper comparing animal-based indicators for health, productivity and behaviour in individually and pair-housed dairy calves. Housing type did not affect health, feed intake or weight gain, but individually-housed calves placed in a new pen scored higher on movement behaviour than pair-housed calves placed in a new pen. This rebound effect indicates that the individual housing of calves results in activity deprivation.

Effects of Holding Density on the Welfare of Zebrafish: A Systematic Review

Marica Andersson, Petronella Kettunen

Published in 2021

A scientific review of the effects of stocking density for juvenile and adult zebrafish used in research on growth, reproduction, stress responses (including behaviour), water quality and disease outbreaks. It recommends that stocking density should be included in guidelines for housing and should be discussed in the materials and methods sections of papers where zebrafish are used.

The Use of Artificial Intelligence in Assessing Affective States in Livestock

Suresh Neethirajan

Published in 2021

A scientific review of the use of artificial intelligence and machine learning to identify and then assess emotions in livestock.  These developments call for a multidisciplinary approach that combines affective computing, bioengineering and applied ethology to overcome both theoretical and practical obstacles.

Detecting Welfare in a Non-Verbal Species: Social/Cultural Biases and Difficulties in Horse Welfare Assessment

Martine Hausberger, Clémence Lesimple, Séverine Henry

Published in 2021

A scientific review investigating the reasons why most domestic horses have unsatisfactory welfare levels despite being very close to humans. It identifies human subjectivity, human misinterpretation of signals sent by horses, and human desensitisation to welfare situations as the main contributing factors. It proposes the promotion of validated indicators to allow horse welfare to be assessed objectively.
