BROTAS, Brazil—A group of volunteers has been trying to save hundreds of buffalos that police say were abandoned on a Brazil dairy farm, where as many as 500 have already died of hunger, according to people involved in the effort.
Environmental police in the town of Brotas, some 150 miles (250 kilometer) from the capital of Sao Paulo, responded to reports of malnourished and mistreated animals on the Sao Luiz da Agua Sumida farm last month.
