Animal welfare professors at Britain's Bristol University, preparing for a
June conference on Compassion in World Farming, said they will present
research to show that cows experience pain, fear and happiness; can form
friendships in a herd; are good problem-solvers (with encephalograph-measured
brainwaves suddenly active when they searched for a path to food); and can
hold grudges against other cows for months or years. [The Australian, 2-28-05]
