  2. 1. An animal without an animal within : investigating the identities of pet keeping

    Author : David Redmalm; Ylva Uggla; Tora Holmberg; Hanna Bertilsson-Rosqvist; Örebro universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; animal studies; animality; anomalies; companion animals; Michel Foucault; Donna Haraway; human-animal studies; materialsemiotics; pets; posthumanism; Sociologi; Sociology;

    Abstract : If the human is an animal without an animal within—a creature that has transcended the animal condition—what is a pet? This creature balancing on the border between nature and culture, simultaneously included in and excluded from a human “we”, is the focus of this thesis. The thesis analyzes the discourses and normative frameworks structuring the meaning of pets in people’s lives. READ MORE

  4. 2. Good enough? Animal welfare in organic poultry production

    Author : Lina Göransson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Outdoor access, reduced stocking densities, natural light, no beak trimming, and ‘slow-growing’ broilers provided with raised sitting areas, are some of the main features of organic poultry production intended to improve bird welfare. On-farm studies are important to increase our knowledge of animal welfare in commercial production. READ MORE

  5. 3. Production of polyclonal antibodies in rabbits and chickens immunised with human immunoglobulin G : A study of the utility of egg yolk antibody production as a substitute for rabbit serum antibody production

    Author : Lise Svendsen Bollen; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Laboratory animals; antibody production; egg yolk; adjuvants; antibody response; avidity; Försöksdjursvetenskap; Laboratory animal science; Försöksdjursvetenskap; zoologisk utvecklingsbiologi; Animal Development;

    Abstract : The utility of chicken egg yolk antibodies as an alternative to rabbit antisera was studied by comparing antibody and avidity development in immunised animals (15 rabbits and 30 chickens) during a one-year immunisation scheme. Human IgG was used as the model antigen and the efficacy of three adjuvants, Freund's Complete Adjuvant, Freund's Incomplete Adjuvant and Hunter's TiterMax, was compared. READ MORE

  6. 4. Methane production in dairy cows : individual cow variability in methane production

    Author : Edward Hernando Cabezas Garcia; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Enteric methane (CH4) emissions vary between individual cows, and this variation is attributed to both animal and dietary factors. In addition, measurement technique of in vivo CH4 emissions from individual animals still represents a major challenge for successful emissions mitigation strategies. READ MORE

  7. 5. Predicting methane production in dairy cows

    Author : Mohammad Ramin; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Methane is a potent greenhouse gas, to which enteric fermentation from ruminants contributes significantly. Reliable and accurate predictions of methane (CH₄) production from dairy cows would be of interest to develop mitigation strategies and for national inventories. READ MORE
