  1. An Overview of Engineering Approaches to Improving Agricultural Animal Welfare.Candace Croney, William Muir, Ji-Qin Ni, Nicole Olynk Widmar & Gary Varner - 2018 - Journal of Agricultural and Environmental Ethics 31 (2):143-159.
    In this essay, we provide an overview of how production systems can be re-engineered to improve the welfare of the animals involved. At least three potential options exist: engineering their environments to better fit the animals, engineering the animals themselves to better fit their environments, and eliminating the animals from the system by growing meat in vitro rather than on farms. The morality of consuming animal products and the conditions under which agricultural animals are maintained remain highly contentious, and when (...)

  • The Ticking Clock: Addressing Farm Animal Welfare in Emerging Countries.Marina A. G. von Keyserlingk & Maria José Hötzel - 2015 - Journal of Agricultural and Environmental Ethics 28 (1):179-195.
    Over the last decade many emerging economies, and in particular Brazil, have established themselves as major players in global food animal production. Within these countries much of the increase in food animal production has been achieved by the adoption of intensive housing systems similar to those found in most industrialized countries. However, it is now well established that many of these systems are associated with numerous welfare problems, particularly with respect to restriction of movement. Previous work has shown that people (...)

  • Attitudes of Canadian Pig Producers Toward Animal Welfare.Jeffrey M. Spooner, Catherine A. Schuppli & David Fraser - 2014 - Journal of Agricultural and Environmental Ethics 27 (4):569-589.
    As part of a larger study eliciting Canadian producer and non-producer views about animal welfare, open-ended, semi-structured interviews were used to explore opinions about animal welfare of 20 Canadian pig producers, most of whom were involved in confinement-based systems. With the exception of the one organic producer, who emphasized the importance of a “natural” life, participants attached overriding importance to biological health and functioning. They saw their efforts as providing pigs with dry, thermally regulated, indoor environments where animals received abundant (...)
