Dehorning – NAHMS studies 2007-08 small producer study 9 8% off calves 9.8% l born b in i East E t had h d horns h vs 22.8% of calves in South Central region 49% of calves born with horns over all regions were or would be dehorned. if dehorned, average age was 119 d = 4 months Dehorning – NAHMS studies Dehorning h tools l for f calves l Lye paste Portasol (butane) and Express (butane/propane mix, larger tip) Electric dehorner Roberts gouge Barnes – small and large Portasol dehorner - butane Commonly, also scoop out the bud Electric dehorners Roberts dehorner – spreads p BLV Barnes dehorners – two sizes Barnes dehorner Need to remove haired skin all the way around Must get haired skin all around Must control bleeding Keystone dehorner Dehorning technique - NAHMS Percent of all operations (operations in East): Caustic paste – 5.7% (3.4%) Electric dehorner,, debudder – 24.5% ((12%)) Roberts gouge or spoon – 30.6% (25.4%) Barnes saw, Barnes, saw or keystone – 39.2% 39 2% (59.2%) (59 2%) What does BQA say?
