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.

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.

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.

No, It’s Not a Murder Hornet.

By now, you’ve probably read headlines about the Asian giant hornets (aka “murder hornets”) that were spotted in Washington state and across the border in Canada. It is important to note that Asian giant hornets have only been confirmed in a small area of Washington and Canada. These wasps have not been observed in South Dakota or our neighboring states.

Why Those Dandelions in Your Yard Aren’t So Bad

While research has shown that pollinators, specifically honey bees, can’t survive on dandelion pollen alone, this doesn’t mean that the dandelions aren’t still important for pollinators.
