Lessons From Alternative Calving Workshops

Recently, the South Dakota Grassland Coalition and SDSU Extension held workshops across the State focused on sharing information from experienced livestock producers who have switched to a calving date more in sync with nature.

Cow Herd Options

April 2018 and 2019 blizzards caused stress to the region’s cowherds, and for some herds changed the calving distribution. 2020 brings a chance to re-establish a preferred calving distribution.

Rancher’s Perspective on Challenging Heifers

This article will share a rancher’s perspective on challenging heifers during the breeding season in Northwestern South Dakota.

Using Increased Longevity to Reduce Annual Cow Cost

When evaluating annual cow cost, feed rises to the top of the list. Feed cost is an important area to consider; however, have you evaluated the cost of incorporating replacement heifers into the cowherd?

Alternative Calving Considerations

Structuring a calving program that best suites farm and ranch operations can be challenging. Of primary concern are: weather, labor, market timing, and animal health considerations, with weather possibly being the most volatile factor, as it ranges from challenging to catastrophic in some years.

Are You Moving Enough Air in Your Calving Barn? Part 2: Effects of ineffective winter ventilation

High humidity, moisture, and increased levels of air contaminants due to ineffective ventilation can lead to significant health issues in our animals. This is especially of concern to our most sensitive sub-population, newborns and the very young. Even calves that receive adequate colostrum and a good nutritional start to life will have health challenges if they live in highly contaminated environments.

Can You “Make” a Cow Deliver Better Colostrum?

Cattle producers and veterinarians are aware of the large body of evidence clearly pointing to the benefits of colostrum for baby calves. As such, much attention has been given to the “intake side” of the equation (the calf’s side): how to ensure a calf consumes an adequate amount of high-quality colostrum.

Pregnancy Diagnosis in Your Cow Calf Herd

Early pregnancy diagnosis and being able to identify AI sired calves from calves sired by clean-up bulls is crucial for maximizing herd productivity and increasing economic return from your cows.
