2. 1. 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

4. 2. Avian IgY antibody : In vitro and in vivo

   Author : David Carlander; Lennart Hammarström; Uppsala universitet; []
   Keywords : Medical sciences; Antigen production; chicken; cystic fibrosis; egg; ELISA; IgY; immunotherapy; Pseudomonas aeruginosa; yolk; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Clinical Chemistry; klinisk kemi;

   Abstract : Immunoglobulin Y (IgY) is the major antibody found in eggs from chicken (Gallus domesticus). IgY can be used as an alternative to mammalian antibodies normally used in research, and its use in immunotherapy has recently been proposed. READ MORE

5. 3. Genomics of heterosis and egg production in White Leghorns

   Author : Esinam Amuzu; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Abstract : Crossbreeding  is  practiced  extensively  in  commercial  breeding  programs  of many  plant and animal species, in order to exploit heterosis, breed complementarity, and  to  protect  pure  line  genetic  material.  The  success  of  commercial  crossbreeding  schemes depends on identifying and using the right combination of breeds, lines or  varieties  that  produce  the  desired  crossbred  offspring.

6. 4. Mapping Genes Affecting Phenotypic Traits in Chicken

   Author : Susanne Kerje; Leif Andersson; Martien Groenen; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; chicken; Quantitative Trait Loci; growth; egg production; epistasis; plumage colour; Extended black; MC1R; Dominant white; PMEL17; Genetik; Clinical genetics; Klinisk genetik;

   Abstract : The purpose of gene mapping is to understand the underlying genetics of simple and complex traits like plumage colour and growth. This thesis is based on a cross between the wild ancestor of the modern chicken, the red junglefowl, and a White Leghorn line selected for high egg mass. READ MORE

7. 5. Domestication effects on foraging behaviour : consequences for adaptability in chickens

   Author : Christina Lindqvist; Per Jensen; Björn Forkman; Linköpings universitet; []
   Keywords : HUMANIORA; HUMANITIES; Etologi; chicken; domestication effects; behaviour; red jungle fowl RJF ; contrafreeloading CFL ; egg production; Ethnology; Etnologi;

   Abstract : The main aim of this thesis was to study domestication effects on foraging behaviour in chickens and to investigate whether and how domestication and selection for high production have influenced adaptability in chickens. Two domestic strains of chickens (egg layers and meat type chickens) and their wild ancestor, the red jungle fowl (RJF) were compared in different test situations with respect to foraging behaviour and adaptability.
