Tables 30 and 31 show the milk and butter-fat yields in 
pounds, and Tables 32 and 33 the yields in per cent., both 
before and after the operation of dehorning. ‘The change | 
from stable to pasture conditions after dehorning resulted in | 
increased yields, but the dehorned group did not regain its 
normal flow, as compared with those not dehorned, until the 
end of thirty days.
