Lowering Effect

Fasting, i.e. depriving the animals of food prior to harvesting, has been practised in the production of house crickets (Acheta domesticus). However, the effectiveness of this method in reducing microbial loads is still unclear. In addition, there may be costs of fasting to the organism, which could compromise product quality and animal welfare. Here, we analysed spontaneous behaviour displayed after 0, 24 or 48 hours of fasting. We show that after 48 hours of fasting, shelter use was increased and the duration spent on the exposed area of the floor was decreased. The same trend was seen after 24 hours fasting. Moreover, in both fasting treatments, a strong reduction in grooming was seen. We conclude that, in the absence of a microbial lowering effect of fasting and considering the current finding that fasting induces behavioural responses in crickets, there is currently no scientific support for using fasting in cricket production.

Convention Theory

Purpose This paper is based on three social scientific studies of animal welfare and local food products in Norway, of which two focussed on sheep in particular. It addresses the widespread belief that Norwegian sheep farming is “the best” but is confronted with a meat industry that emphasises economic efficiency. A few years after a new Norwegian law on animal welfare acknowledged animals as sentient beings came into force in 2010 (LOVdata, 2009), the purpose of this paper is to better understand ongoing debates on the welfare of sheep by exploring how sheep welfare is understood and regulated in Norway. Design/methodology/approach The theoretical framework draws on convention theory, especially referring to the four “possible worlds of production” (Salais and Storper, 1993). The authors argue that animal welfare may be analysed in parallel to product quality, focussing on three major perspectives of sheep welfare: animal treatment, product quality, and an abstract conceptualisation in public discourse. The empirical analysis is based on interviews with key players in the sector and central documents. Findings Convention theory points to several general difficulties in reaching an agreement on what is “good quality” and welfare. First, the authors find difficulty in how to implement new regulatory conceptualisations with dominant ways of understanding welfare within the industry. Second, the idealised images of sheep welfare of an immaterial possible world dominating public discourse have very little interaction with the real world of farms and abattoirs. Originality/value This paper suggests that rather than addressing and handling the potential tension between the legal recognition of animal as sentient being and the economic demands of the industry, key actors keep the potentially conflicting understandings apart in different “worlds of production” (Salais and Storper, 1993). Nevertheless, the authors observe that interactions between possible worlds, as well as translation from one possible world to another, not only could be promising but would be fundamental to concretise improvements in the real world.

Abstract This article examines the legislative basis and operational effectiveness of the national and prefectural systems for designating and promoting traditional crafts in Tokyo. Traditional artisans participate in these systems primarily through their involvement in kumiai ('artisan guilds'), whose historical background and organizational structure are briefly summarized. To evaluate the usefulness of government support for contemporary craft practitioners, four broad and interrelated categories of kumiai activities are examined: promoting craft business, maintaining and enhancing craft skills and product quality, securing the future of craft traditions, and procuring craft materials. These goals are reflected in the frameworks of national and prefectural legislation that aims to support the efforts of kumiai. However, these goals and the resulting legislation have created a sustained discourse of tension palpably felt by many crafters themselves: the clash between laws designed to protect or promote 'traditional' crafts and other laws that aim to safeguard ecology or animal welfare. Examination of this tension as it is understood and discussed by artisans themselves reveals that, although the positive impact of traditional craft designation systems is widely recognized, it is also perceived that incompatible environmental protection laws can negatively affect their business and threaten the long-term sustainability of craft traditions.

A significant proportion of the African continent is conducive for animal agricultural production, due to its historical experience and available resources to accommodate and nurture various indigenous and exotic animal species and breeds. With food security being a global challenge, animal products can play an important role as nutrient dense food sources in human diets, particularly in Africa. However, this does not seem to reach its full potential in practice, due to numerous reasons that have not been adequately addressed. Animal welfare reservations can be highlighted as one of the major contributing factors to the curbed progress. The consequences have been scientifically proven to affect product quality and market access. However, in the African community, the concept of animal welfare has not been fully embraced. While there are international animal welfare standards in the developed world, there are inherent factors that hinder adoption of such initiatives in most developing regions, particularly among communal farmers. These include cultural norms and practices, social ranking, socio-economic status, available resources, information dissemination and monitoring tools. Therefore, there is need to harmonize what is internationally required and what is feasible to accommodate global variability. The protocols followed to ensure and evaluate farm animal welfare require regular investigation, innovation and a sustainable approach to enhance animal productivity, efficiency and product quality. Additionally, investing in animal wellbeing and health, as well as empowering communities with significant knowledge, has a potential to improve African livelihoods and contribute to food security. This review seeks to highlight the concept of animal welfare in relation to livestock and food production in African conditions.

As part of a continual search for potential pathogens of insects for use in biological control or on an integrated pest management program, two bacilliform virus-like particles (VLP) of similar morphology have been found in the Mexican bean beetle Epilachna varivestis Mulsant and the house cricket, Acheta domesticus (L. ).Tissues of diseased larvae and adults of E. varivestis and all developmental stages of A. domesticus were fixed according to procedures previously described. While the bean beetles displayed no external symptoms, the diseased crickets displayed a twitching and shaking of the metathoracic legs and a lowered rate of activity.Examinations of larvae and adult Mexican bean beetles collected in the field in 1976 and 1977 in Maryland and field collected specimens brought into the lab in the fall and reared through several generations revealed that specimens from each collection contained vesicles in the cytoplasm of the midgut filled with hundreds of these VLP's which were enveloped and measured approximately 16-25 nm x 55-110 nm, the shorter VLP's generally having the greater width (Fig. 1).

Production Conditions

Innovators of in vitro meat (IVM) are convinced that this approach is the solution for problems related to current meat production and consumption, especially regarding animal welfare and environmental issues. However, the production conditions have yet to be fully clarified and there is still a lack of ethical discourses and critical debates on IVM. In consequence, discussion about the ethical justifiability and desirability of IVM remains hypothetical and we have to question those promises. This paper addresses the complex ethical aspects associated with IVM and the questions of whether, and under what conditions, the production of IVM represents an ethically justifiable solution for existing problems, especially in view of animal welfare, the environment, and society. There are particular hopes regarding the benefits that IVM could bring to animal welfare and the environment, but there are also strong doubts about their ethical benefits.
