BRD (aka pneumonia) come in different bacterial and viral strains..the viral ones are the worst, and often the ones that will take a calf the quickest if not treated right away.
Merck Veterinary Manual on BRD has some possible types of pnuemonia that could infect cattle. Some don't hit all that fast like ladycat says, others do.
Symptoms, from mild to serious, are snotty nose, coughing, decreased feed intake, raspy breathing, resting and not chewing cud, head droopy and eyes and ears not bright and perky, lethargic, laboured breathing, high temperature, dry nose, then eventually death if not caught and treated. Best times to see if an animal is sick with pneumonia is the first signs: "frequent" coughing, and yellowy opaque snot in the calf's nose.
