From disbudding ( Day @ ) to Day @ farmer-disbudded calves receiving meloxicam grew faster ( @ kg/day ) than calves without meloxicam ( @ kg/day ; p = @ ) , but an interaction between operator and meloxicam treatment ( p = @ ) meant that meloxicam treatment did not increase growth rates in veterinary-disbudded calves ( @ vs. @ kg/day ; p = @ ) .
