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.

Invited review: Freedom from thirst-Do dairy cows and calves have sufficient access to drinking water?

Margit BakJensen, Mogens Vestergaard

Published in 2021

Scientific review of what is known about the water requirements of 1) young calves, depending on their feeding regime (ad libitum or limited milk), state of health and ambient temperature; 2) dairy cows, depending on their milk yield, feed composition and housing (under cover or on pasture). It concludes that research on the length and positioning of water troughs is needed.
