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.

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.

How Important Is Water Quality to Livestock?

Water is the most important nutrient to all livestock animals and is sometimes overlooked. Poor quality water can have a negative effect on growth, reproduction, and general productivity of the animal.

How Do Sulfates in Water Affect Livestock Health?

Poor-quality water will cause an animal to drink less. As a result, they also consume less forage and feed, which leads to weight loss, decreased milk production and lower fertility.

Managing Livestock for Dung Beetles and Other Beneficial Species

South Dakota researchers have taken a closer look at the function of dung beetles in Eastern South Dakota over the last few years. This article summarizes findings related to management of livestock grazing and chemical pesticides in relation to dung beetle and insect community health.
