Abstract

This study investigated dag accumulation between marking time and first shearing and wool cover of the tip of the tail in a total of 842 ewes and wethers, tailed either at the second or third joint using a standard gas knife or at the third joint using the Te Pari Patesco gas knife. Four hundred of the ewes had further measurements taken in 2011. The Te Pari-treated animals had significantly (P < 0.05) less wool on the tail tip than lambs treated with a standard gas knife. There were no significant differences in dag score between treatment groups in 2010; however, there were significantly (P < 0.05) less dags on animals in the Te Pari-treated group in 2011. This effect needs to be further investigated in a range of sheep genotypes, locations and seasons.
