Abstract

The proposal is to purchase electronic feeders, control equipment for the feeders and an automatic weigh station that will underpin a programme of research in detecting and locating quantitative trait loci (QTL: single genes have a large effect on performance) in cattle, which provide 40 percent of all agricultural outputs in the UK. A genome mapping approach will be taken. The specific objectives are to locate chromosomal regions with large effects on the performance of cattle in: (i) weight, weight gain and carcass composition; (ii) feed intake and feed efficiency for growth and lean growth; (iii) feed intake and feed efficiency during lactation. The analysis will identify QTL and investigate pleiotropic effects, including traits measured as part of other proposals. The results will provide information basic to our understanding of quantitative genetic variation. Emphasis on feed efficiency is justified since it is a key factor in maintaining the international competitiveness of the UK industry, yet this needs to be achieved without any compromise on health and welfare. The measurement of efficiency requires the measurement of feed intake which will be enabled by the equipment requested.
