What Goes Into Calculating Yardage?

Yardage cost is the non-feed cost per head for every day that an animal is fed harvested feed in some form of confinement. Yardage is usually associated with calves and yearlings in the feedlot, but this concept can apply to drylotted or wintering cows as well.

Valuing High-Moisture Corn and Earlage

A key advantage to using commodities that meet standard specifications and are frequently traded is that it is very easy to establish an economic value that is accepted by most users. The marketplace sets the value of corn, and other feedstuffs on a daily basis, provided those products meet some set of standard specifications.

Prussic Acid Poisoning

As the first frost date approaches, producers often have concerns about the risk of prussic acid poisoning in livestock. Certain forage plants, especially sorghums and related species are associated with an increased risk of death loss because of prussic acid poisoning.

Multi-Species Grazing as an Alternative to Pasture Spraying

Broadacre spraying of pastures is intended to reduce undesirable plants and increase grasses for livestock. This practice often results in unintended consequences, including damage and reduction of native forbs and reduced profitability. One approach to managing perceived “weedy” plants is incorporating different species of livestock into a grazing operation.

Ergot in Western Wheatgrass and the Potential Effects for Winter Grazing

2019 has been a year fraught with challenges for ranchers across South Dakota. Abundant precipitation is usually a blessing, however, wet conditions coupled with a cool spring followed by warmer temperatures has caused another problem across the rangelands of South Dakota: ergot poisoning.

Managing Weeds While Transforming Marginal Land Into Perennial Forages Production

There are currently millions acres across South Dakota impacted by saline and sodic conditions. Research has shown that salt-tolerant perennial grasses are a possible way to bring land back into production.

Farm Practices That Improve Soil Health: Integrated Crop-Livestock Systems

An integrated crop-livestock system can provide an alternative management strategy that benefits producer’s income, soil health, and the environment—all while increasing production.

Choosing the Right Custom Feeding Partner

Custom cattle feeding can be a “win-win” strategy when done correctly. Feeding someone else’s cattle provides a method to market feedstuffs without tying up the capital required to own the livestock.

Weed Control: Noxious Weeds

Noxious Weed Recommendations: Herbicides for pasture, range, and non-crop areas, including roadside and other right-of-way that may be harvested for hay or grazed, are given a priority.
