Calving Season Benchmarks

Reproductive performance of an operation is important to the overall success and bottom line of that operation. Benchmarking may be beneficial as it can help focus limited management time on critical areas of an individual’s beef cow business.

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.

How Many Bulls Do You Need When Synchronizing With Natural Service?

The use of estrous synchronization with natural service provides an opportunity to utilize the benefits of synchronization. However, the first question producers ask is, “How many more bulls do I need?"

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.

Minimizing Synchronization Costs

With the rising costs of certain feed supplements, uncertainty in the markets, and fear of the unknown, using an estrus synchronization protocol may be the last thing on producers’ minds. However, there is still opportunity to incorporate estrus synchronization without breaking the bank.
