Pre-weaning Pneumonia in South Dakota Beef Herd: A Persistent Problem, Suddenly Gone

This case report describes a southeastern South Dakota cow-calf herd’s experiences with pre-weaning pneumonia. Unlike many beef herds that experience pneumonia in calves on pasture, this herd’s problems were consistent year after year: widespread calf illness was documented in each of 6 consecutive summers. Anecdotally at least, the occurrence of pre-weaning pneumonia in beef herds is more likely to be sporadic and unpredictable from year to year. This herd’s persistent problems were followed by a year in which, after a change in calf vaccination protocol (informed by herd diagnostics), very little pre-weaning pneumonia was observed.

Lawn Weed Control

Cultural weed control practices must be included in weed management programs to optimize control and inhibit re-infestation. A healthy, dense turf cover is the best overall defense against weed invasion. Some common cultural weed control practices include planting the most adapted turfgrass species for your environment (i.e. shade, full sun, or hot, dry conditions), maintaining a mowing height of 2.5–3.5 inches, watering deeply but less frequently, and proper soil maintenance including fertilization and core aerification.
