1. 1. Skip-a-day feeding does not cause difference in liver lipid content in broiler breeders

   Kandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

   Författare :Elin Sander; [2017]
   Nyckelord :Broiler breeders; dry weight; feed restriction; lipids; liver; skip-a-day;

   Sammanfattning : There has long been evidence for increased lipids in the liver of chickens exposed to feed restriction, commonly used for production hens. Lipogenesis is an important part of the metabolism and storing of glucose, a source of energy. LÄS MER

3. 2. Physiological stress and behavioural differences in broiler breeder hens subjected to daily and 5:2 feed restriction regimens

   Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

   Författare :Alexandra Johansson; [2016]
   Nyckelord :Broiler breeder; feed restriction; H L ratio; skip-a-day; stress; welfare;

   Sammanfattning : Feed restriction in the parental stock of meat producing chickens, broiler breeders, is essential in order to decrease the high growth rate that they are genetically selected for. The feed restriction does however lead to chronic hunger and stress. LÄS MER

4. 3. Poor welfare or future investment? Different growth pattern of broiler breeders

   Master-uppsats, Linköpings universitet/Biologi; Linköpings universitet/Tekniska fakulteten

   Författare :Andreas Calais; [2015]
   Nyckelord :Chicken; broiler breeder; welfare; stress; hunger; feed restriction; skip-a-day; morphometrics.;

   Sammanfattning : The parental stock of meat type chickens (broiler breeders) are commonly feed restricted to decrease their rapid growth and the issues associated with it. Among these birds, chronic hunger and stress are the most prominent welfare concerns and mass heterogeneity within flocks a major management challenge. LÄS MER
