Last I checked, the best estimates of the impact of direct subsidies on cost seemed to be around 1-2% of cost for beef and pork and less than that for chicken/eggs/milk. (Can't find this now, so lower credibility, but AI estimates seem to agree) Based on this, removing them would be great, but probably wouldn't be tractable enough compared to other interventions given the difficulty.
