Animal welfare science: an integral piece of sustainable insect agriculture

Abstract

The insects as food and feed (IAFF) industry represents one of the largest undertakings of industrial livestock rearing in human history, with at least a trillion animals reared each year and massive growth potential. As other livestock industries have grown, animal welfare science has become an essential field for maintaining socially responsible, ethical, and sustainable industry practice. Like traditional livestock industries, the IAFF industry could also benefit – ethically, socially, and economically – from a field of welfare science. Here, we present three economic reasons for considering animal welfare in intensive production systems: (1) improving production outcomes, (2) maintaining social license to operate, and (3) differentiating products. In each case, we provide examples from established livestock industries that highlight how the field of animal welfare science can benefit producers. Further, we provide examples of how the IAFF industry would benefit from the support of a dedicated field of welfare science. We end by calling attention to key partnerships between entomologists, welfare scientists, and producers that could advance the common goals of these stakeholder groups, as well as animal welfare in insect agriculture.
