A study is described which is unique in that resistance to each of the major diseases which affect production in Merino sheep was measured in the same flock under the same environmental conditions. Results indicated that within the one flock, genetic variation exists for resistance to internal parasites, foot-rot, fleece rot and dermatophilosis. Heritability estimates were similar to those publ...
The total genome sequence of the archaeon Methanococcus jannaschii completes the trilogy of genomes for the three domains of life-Archaea, Bacteria and Eucarya. It will have far-reaching consequences for evolutionary studies and for the way in which experimental biology is performed.
Smooth golden fleece (Urospermum dalechampii (L.) F.W. Schmidt) and prickly picroides Scop. ex Schmid) are two wild edible plants used in traditional cuisine folk medicine. In this research, the domestication of both species was tested for first time using a floating system plant densities (412 824 m?2) to evaluate yield quality. Some quality traits were also compared cultivated ones gathered g...
The developments in Norwegian sheep breeding since the early 1990s are reviewed. For the largest breeding population, the Norwegian White Sheep, results are presented for both genetic and phenotypic changes. Of the nine traits that make up the aggregate genotype, the largest gain per year, in per cent of the corresponding phenotypic average, was found for carcass grade (1.66%) and carcass weigh...
The objective of this study was to determine the genetic parameters of methane (CH4) emissions and their genetic correlations with key production traits. The trial measured the CH4 emissions, at 5-min intervals, from 1225 sheep placed in respiration chambers for 2 days, with repeat measurements 2 weeks later for another 2 days. They were fed in the chambers, based on live weight, a pelleted luc...
