Common infectious agents of calf scours include coccidia, coronavirus, Cryptosporidium, Escherichia coli, rotavirus and Salmonella.  Understand that any and all of these agents can cause scours when host immunity is low and environmental conditions create stress and high rates of transmission.  These disease agents are mostly opportunistic, in that they are often present on farms with scours problems and also on farms without scours problems. Management and environment are often the factors that are most easily changed to control the disease problem.
