  • How Does Respeggt Gmbh Live up to the Promise of “Free of Chick Culling”?
    FAQ What does the respeggt GmbH do? We, the respeggt GmbH, hold the rights to the respeggt label “Free of Chick Culling”. The label represents the promise that the table eggs and the egg products in foodstuffs have been produced free of the usual “chick culling” of day-old male chicks. This product promise is based on the implementation of a method for gender identification in the hatching egg. At the end of the 21-22 days incubation period, the laying hen chicks hatch from the fertilised hatching eggs. Usually, the male chicks, who hatch alongside the females, are killed in the hatcheries since they are unable to lay eggs. Only the female chicks are reared and later lay the table eggs as adult laying hens. Gender identification in the hatching egg allows the male hatching eggs to be identified and sorted out during the incubation period. As a result, only the female hatching eggs are incubated until the end. This way we avoid killing the day-old male chicks. We offer all hatcheries the service of gender identification in the hatching egg to sort their hatching eggs. This service is offered to hatcheries at no extra cost. Only when the subsequently produced table eggs are sold, do we charge the packing centres a licence fee per table egg. A major advantage of this approach is that smaller hatcheries will still be able to compete in the market. No extra investment is required in order to implement the process of gender identification in the hatching egg and to sell female chicks with the label “Free of Chick Culling”.

However, the technology raises new ethical concerns which relate to the sensitivity of the embryo, as well as how the screened out eggs will be used afterwards and the accuracy of gender determination. In order to comprehensively investigate consumer attitudes towards this new technology, a questionnaire including a choice experiment was distributed to a representative sample of 482 German consumers between December 2018 and March 2019. The data was analyzed by an explorative factor analysis and a latent class analysis. Results indicate that the sample can be divided into four segments, which differ in preferences for production attributes, attitudes and price sensitivity. Attitudinal differences are found regarding respondents’ approval of the technical advances in agricultural production, confidence in legal regulations and the endorsement of enhanced livestock production conditions. Both a meaningful usage of by-products and a high rate of accuracy are crucial factors for the acceptance of in ovo gender determination for the majority of respondents. However, response behavior of one segment, representing 11% of the sample, indicates the disapproval of both chick culling and in ovo screening.

  • A Critical Discourse Analysis of the Animals Farmed Series in the Guardian
    “It Would Be Kinder to Shoot Them” A Critical Discourse Analysis of the Animals Farmed Series in The Guardian Lukas Leitinger Supervisor: Núria Almiron Academic Year: 2019/20 Research project of the MA in International Studies in Media, Power, and Difference Department of Communication Universitat Pompeu Fabra, Barcelona Abstract This study conducted a critical discourse analysis on the Animals farmed series in The Guardian. To this end, the messages of the 196 articles from the launch of the series until April 20, 2020 and 8 articles from outside the series were analysed. Predominantly, the language of the series reinforces animal oppression by only asking how, not if, we should farm nonhuman animals. Some articles in the series show farmed animals’ suffering and workers’ ethical dilemmas, yet thorough challenges to animal oppression were only found outside the series. Thus, the study identified an underlying welfarist ideology throughout Animals farmed. Additionally, this study conducted a political economy analysis to explore the economic pressures behind the series. This analysis revealed links to the animal industry and philanthropy, which helps explain the findings. With these findings, the study contributes to critical animal and media studies and to journalism fighting animal oppression.

  • Cetology and Crustaceology in Moby-Dick and “Consider the Lobster”
    Ethics and Semiogenic Construction of Other Animals: Cetology and Crustaceology in Moby-Dick and “Consider the Lobster” By Eva Natalia Kasprzycka A Thesis submitted to the Faculty of Graduate Studies of The University of Manitoba in partial fulfilment of the requirements of the degree of MASTER OF ARTS Department of English, Film, Theatre and Media University of Manitoba Winnipeg Copyright © 2019 by Eva Kasprzycki i Abstract This thesis brings together a ten-page essay on lobsters and a 700-page book on whales to scrutinize the semiogenic construction of creatures floating in the political animal menagerie. Herman Melville’s novel Moby-Dick and David Foster Wallace’s essay “Consider the Lobster” are texts that are fundamentally concerned with the ethical stakes of textual and historical representations of cetaceans and crustaceans. Both these works explore the intersection between the unknowability of nonhuman animal subjectivity and the industrial rendering of nonhuman animal bodies —an intersection paved and maintained by biopolitical agents that emphasize the former so that the latter can occur without criticism. Despite being published 154 years apart, both these works use the New England coastline to portray industries of death and devouring, both of which are centres of epistemological ambiguity for Wallace and Melville. By theoretically unpacking the political, cultural and historical portrayal of crustaceans and cetaceans in these two literary works, this thesis pursues some of the intra-active networks —in particular those of speciesist ideology— that encase and weave together the industrialized biocapital of nonhuman bodies to the aesthetic representation of them. ii Acknowledgements First, I would like to thank the Department of English, Film and Theatre for the financial support that made this endeavour a lot easier.

  • Rearing Male Layer Chickens: a German Perspective
    agriculture Brief Report Rearing Male Layer Chickens: A German Perspective Mona Franziska Giersberg * and Nicole Kemper Institute for Animal Hygiene, Animal Welfare and Farm Animal Behaviour, University of Veterinary Medicine Hannover, 30173 Hanover, Germany; [email protected] * Correspondence: [email protected]; Tel.: +49-511-856-8963 Received: 19 October 2018; Accepted: 6 November 2018; Published: 9 November 2018 Abstract: The killing of male layer hybrids in the hatcheries, at a day-old, is common practice but it also raises strong socio-ethical concerns. In recent years, three different approaches to avoid this killing have been developed—the in ovo sex determination, the rearing of male layers for meat, and the use of dual-purpose breeds. In Germany, about one million male layers are raised each year in the organic and conventional sector. Regarding animal health and welfare, this concept seems favourable. However, the main challenge, that is, to what extent these animals can be kept in a resource-friendly and ecologically sustainable way, remains yet to be solved. Currently, for a niche, this approach contributes to the diversification of the German market. It serves as an example for reacting to societal concerns immediately, before feasible solutions are available for the entire system of modern poultry production. Keywords: animal welfare; animal ethics; poultry; culling; day-old chickens; sustainability 1. Introduction The genetically-determined antagonism between reproduction and fattening performance in chickens has led to specialised hybrids for egg and meat production. In broiler hybrids, both sexes are used for meat production. However, since male layer chickens are not suitable for economic fattening purposes, they are usually killed by maceration or carbon dioxide, in the hatcheries, at a day-old.
