1. Gene Expression in the Brains of Two Lines of Chicken Divergently Selected for High and Low Body Weight
Sammanfattning : Artificial divergent selection of chickens for high and low body weight at 8 weeks of age has produced two lines: the high (HWS) and low (LWS) body weight chicken lines. In addition to the difference in body weight, the lines show extreme differences in feeding behaviour and body composition. LÄS MER
2. Chicken Genomics - Linkage and QTL mapping
Sammanfattning : This thesis presents results from genetic studies conducted in the chicken (Gallus gallus). The domestication of chicken is believed to have been initiated approximately 7,000 – 9,000 years ago in Southeast Asia. LÄS MER
3. Mapping and functional characterization of candidate genes and mutations for chicken growth : an approach combining computational genetics and bioinformatics
Sammanfattning : Knowledge of the genetics related to growth is important for breeding chickens with the desired traits of rapid and efficient growth. A long-term selection experiment in the domestic chicken (Gallus gallus) has resulted in two highly divergent lines selected for juvenile body weight. LÄS MER
4. Fish Community Structure and the Role of Non-Indigenous Species Associated to Seagrass Ecosystems of Eastern Mediterranean
Sammanfattning : Temporal and spatial variation in density, biomass and body size of littoral fish species associated with near shore Posidonia oceanica meadows were studied throughout an annual cycle in an area of eastern Mediterranean. Approximately 109350 littoral fish were collected, belonging to 34 families and 88 species. LÄS MER
5. Nutrition of Arctic charr (Salvelinus alpinus) and Eurasian perch (Perca fluviatilis) and evaluation of alternative protein sources
Sammanfattning : The aim of this thesis was to estimate the dietary lysine requirement of Eurasian perch (Perca fluviatilis), to study the digestive enzyme activity in perch and Arctic charr (Salvelinus alpinus) and the utilization of meals of microbial and mussel meals. Juvenile Eurasian perch were fed semi-purified diets containing graded levels of lysine (12. LÄS MER
