Transgenesis In Animal Agriculture: Addressing Animal Health And Welfare Concerns, Michael Greger
Transgenesis In Animal Agriculture: Addressing Animal Health And Welfare Concerns, Michael Greger
Michael Greger, MD, FACLM
The US Food and Drug Administration’s final Guidance for Industry on the regulation of transgenesis in animal agriculture has paved the way for the commercialization of genetically engineered (GE) farm animals. The production-related diseases associated with extant breeding technologies are reviewed, as well as the predictable welfare consequences of continued emphasis on prolificacy at the potential expense of physical fitness. Areas in which biotechnology could be used to improve the welfare of animals while maintaining profitability are explored along with regulatory schema to improve agency integration in GE animal oversight.
Trait Selection And Welfare Of Genetically Engineered Animals In Agriculture, Michael Greger
Trait Selection And Welfare Of Genetically Engineered Animals In Agriculture, Michael Greger
Michael Greger, MD, FACLM
The release of the Final Guidance from the US Food and Drug Administration on the commercialization of genetically engineered animals has sparked renewed discussion over the ethical, consumer, and regulatory implications of transgenesis in animal agriculture. Animal welfare critiques have focused on unexpected phenotypic effects in animals used in transgenic research, rather than on the health and welfare implications of the intended productivity enhancement. Unless breeding goals are redefined to reflect social concerns, the occurrence and magnitude of undesirable side effects may increase and consumer confidence in the nascent technology may be undermined.
The Applicability Of The Self-Fulfillment Account Of Welfare To Nonhuman Animals, Babies, And Mentally Disabled Humans, Tatjana Visak, Jonathan Balcombe
The Applicability Of The Self-Fulfillment Account Of Welfare To Nonhuman Animals, Babies, And Mentally Disabled Humans, Tatjana Visak, Jonathan Balcombe
Jonathan Balcombe, PhD
In this paper we will argue that generality is a virtue of Haybron’s account of welfare. Indeed, reflecting on the applicability of his theory to nonhuman animals will give us a better understanding of its applicability to humans. We will first focus on self-fulfillment and suggest an interpretation of Haybron’s account according to which the self-fulfillment of an individual consists in the fulfillment of the aspects of the self that are applicable to that particular individual. This makes Haybron’s account of welfare applicable to all sentient beings. Then we will focus on sub-personal nature-fulfillment and argue that the same interpretation …

Sentience Collection
Although environmental enrichment is known to improve laboratory rodent wellbeing and enhance scientific data collection, relatively little is known with regards to the type of enrichment that might be useful for zebrafish (Danio rerio). Therefore, this study explored if zebrafish displayed preferences for a range of enrichments, including substrates, artificial plants, combinations thereof and airstones. Tanks divided into two compartments containing different enrichment cues were used to determine the preferences of zebrafish housed in pairs and groups of eight. When comparing time spent in enriched versus barren compartments, dominant individuals in a pair displayed a preference for substrate and behaviourally …
