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.

Prevalence of Potential Indicators of Welfare Status in Young Calves at Meat Processing Premises in New Zealand

Anna L. Palmer, Ngaio J. Beausoleil, Alana C. Boulton, Naomi Cogger

Published in 2021

A scientific paper assessing the welfare of calves in the holding areas of abattoirs in New Zealand, using group and individual animal-based indicators. It proposes relevant indicators, recommending that they should be systematically incorporated into the protocols used to assess the welfare of calves at slaughter.

Slaughter of Pregnant Cattle at an Austrian Abattoir: Prevalence and Gestational Age

Ignaz Zitterer, Peter Paulsen

Published in 2021

Scientific paper to determine the percentage of pregnant cows and heifers slaughtered in a medium-sized Austrian slaughterhouse. The observed prevalences are much higher than estimated (6.4% as against an estimated 2.5%). The article recommends that measures should be taken to avoid sending pregnant cows to slaughter for ethical and public health reasons.

Long-Distance Transport of Finisher Pigs in the Iberian Peninsula: Effects of Season on Thermal and Enthalpy Conditions, Welfare Indicators and Meat pH

Genaro C. Miranda-de la Lama, Rubén Bermejo-Poza,Formoso-Rafferty, Malcolm Mitchell, Pilar Barreiro, Morris Villarroel

Published in 2021

A scientific paper to determine the influence of temperature and air enthalpy variations in live pig transport vehicles using welfare indicators. It shows that such variations are greater in winter, and are associated with higher cortisol and lower blood glucose levels in pigs, both indicators of heat stress.

Strepsirrhine Primate Training Programs in North American Institutions: Status and Implications for Future Welfare Assessment

Gloria Fernández-Lázaro, Meg H. Dye, Christie Eddie, Gina M. Ferrie

Published in 2021

Scientific paper to evaluate the impact of strepsirrhinia education programmes in North American zoos. Respondents consider that these programmes increase positive human-animal interactions, psychological well-being and staff awareness of animal behaviour. The paper suggests that further work on their impact on the welfare of strepsirrhinia is required.

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.

Computational Fluid Dynamics Analysis of Alternative Ventilation Schemes in Cage-Free Poultry Housing

Long Chen, Eileen E. Fabian-Wheeler, John M. Cimbala, Dan Hofstetter, Paul Patterson

Published in 2021

Scientific paper presenting and testing computational fluid dynamics models under 4 different sets of ventilation conditions to simulate airflow in cage-free chicken houses. The transition to cage-free rearing calls for changes to environmental conditions to ensure the best quality of animal welfare.

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.

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.
