Contributor(s):: Macfarlane, J. M., Matheson, S. M., Dwyer, C. M.
This study investigates the genetic basis of lamb vigour (defined as neonatal lamb activity and sucking ability) and lambing difficulty as potential traits to be included in selection programmes to improve ewe and lamb welfare. Scores for lamb birth difficulty, vigour and sucking ability were...
Genotype rather than non-genetic behavioural transmission determines the temperament of Merino lambs
Contributor(s):: Bickell, S., Poindron, P., Nowak, R., Chadwick, A., Ferguson, D., Blache, D.
Merino ewes have been selected, over 18 generations, for calm (C) or nervous (N) temperament using an arena test and an isolation box test. We investigated the relative contributions of genotype versus the post-partum behaviour of the dam on the temperament of the lambs using a cross-fostering...
