Are You Moving Enough Air in Your Calving Barn? Part 3: Ventilation requirements

Appropriate environments for calving barns are critical to give calves the best start when being born in cold weather. Calves require a dry, clean environment, with lots of fresh air and protection from the wind. A dry and clean environment is critical to avoid transmission of both scours and respiratory disease organisms, and this is primarily accomplished by providing clean bedding and proper ventilation.

Seedcorn Maggot Degree Day Activity Estimates: May 27, 2021

In South Dakota, we have accumulated enough degree days across the state that the peak emergence of the overwintering seedcorn maggot population has passed. In most of South Dakota, we are at peak emergence of the second generation or slightly past it.

Common Stalk Borer Activity Estimate: May 27, 2021

Throughout South Dakota, we still haven’t accumulated enough degree days for common stalk borers to begin moving into corn, which is a good thing. At this point in time, common stalk borer activity is still going to be limited to weeds and grassy weeds.
