Two of the causes of lamb mortality are (1) dystocia and (2) low vigour lambs. Both of these problems require high levels of human intervention to ensure survival of the lambs. Therefore, selection for traits requiring lower levels of input is desirable. The New Zealand strain of Suffolks has purportedly been selected for low input ‘easy care’ traits and represents the possibility of introducing genes for improved lambing ease and lamb vigour into the British Suffolk strains. The aim of this study was to compare birth, neonatal behaviour traits and dag scores of lambs sired by one of three main Suffolk strains.
