Bringing compassion to the ethical dilemma in killing kangaroos for conservation – comment on “Conservation Through Sustainable Use” by Rob Irvine

Ethical debate on the killing of kangaroos has polarised conservation and animal welfare science, yet at the heart of these scientific disciplines is the unifying aim of reducing harm to non-human animals.

This aim provides the foundation for common ground, culminating in the development of compassionate conservation principles that seek to provide mechanisms for achieving both conservation . . . → Read More: Bringing compassion to the ethical dilemma in killing kangaroos for conservation – comment on “Conservation Through Sustainable Use” by Rob Irvine

Inter-observer agreement, diagnostic sensitivity and specificity of animal-based indicators of young lamb welfare

A scientific literature review and consensus of expert opinion used the welfare definitions provided by the Farm Animal Welfare Council (FAWC) Five Freedoms as the framework for selecting a set of animal-based indicators that were sensitive to the current on-farm welfare issues of young lambs (aged ⩽6 weeks). Ten animal-based indicators assessed by observation – demeanour, . . . → Read More: Inter-observer agreement, diagnostic sensitivity and specificity of animal-based indicators of young lamb welfare

Physiological and behavioural responses of poultry exposed to gas-filled high expansion foam

Disease control measures require poultry to be killed on farms to minimise the risk of disease being transmitted to other poultry and, in some cases, to protect public health. We assessed the welfare implications for poultry of the use of high-expansion gas-filled foam as a potentially humane, emergency killing method. In laboratory trials, broiler chickens, adult . . . → Read More: Physiological and behavioural responses of poultry exposed to gas-filled high expansion foam

Rat aversion to isoflurane versus carbon dioxide

Some experts suggest that sedation of laboratory rodents with isoflurane before euthanasia with carbon dioxide (CO(2)) is a humane alternative to euthanasia with CO(2) alone, but little research has compared aversion with these agents. Albino rats were tested in a light-dark box where they had the choice between remaining in a dark compartment filling with . . . → Read More: Rat aversion to isoflurane versus carbon dioxide
