BACKGROUND A major challenge in sheep farming during the grazing season along the coast of south-western Norway is tick-borne fever (TBF) caused by the bacteria Anaplasma phagocytophilum that is transmitted by the tick Ixodes ricinus. METHODS A study was carried out in 2007 and 2008 to examine the prevalence of A. phagocytophilum infection and effect on(More)
A comparison of linear (LM), threshold (TM), and Poisson (PM) mixed models for genetic analysis of number of lambs born (NLB) from 1-yr-old ewes was conducted using 37,718 and 18,633 records of two Norwegian breeds, Dala and Spaelsau, respectively. Models fitted included flock-year as a fixed effect and the random effect of sire. In the Poisson model, the(More)
Chicken meat with reduced concentration of arachidonic acid (AA) and reduced ratio between omega-6 and omega-3 fatty acids has potential health benefits because a reduction in AA intake dampens prostanoid signaling, and the proportion between omega-6 and omega-3 fatty acids is too high in our diet. Analyses for fatty acid determination are expensive, and(More)
The aim of the study was to estimate genetic parameters for direct and social genetic effects (SGE) for growth and welfare traits in farmed Atlantic cod (Gadus morhua). A SGE refers to the effect of an individual’s genes on trait performance of its social partners. In total, 2100 individually tagged juveniles from 100 families at an average age of 222 days(More)
Experiments to evaluate the GIFT strain performance and genetic correlation of Nile tilapia (Oreochromis niloticus) were conducted at Research Institute for Aquaculture No.1 (RIA.1) in northern Vietnam during 3 years from 1999. The fish were reproduced, stocked and evaluated in fresh and brackish water (shrimp) earthen ponds. Heritability and genetic(More)
