Check calves’ ears when resting

When it comes to detecting mycoplasma pneumonia in calves, most producers know to look for droopy ears. However, if the only time you look at calves’ ears is at feeding time, you will probably miss the early signs of this disease, explains Ricardo Rosenbusch, professor of veterinary microbiology at Iowa State University. That’s because at feeding time a calf in the early stages of mycoplasma pneumonia will perk up her ears the same as a well calf. If you want to check your calves’ ears for droopiness, you must observe them when they are at rest — not right before feeding.
