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.

Weaning Calves on Cover Crops

What do we do if it is time to wean calves, but the pen isn’t ready? That can be a real concern during wet fall seasons, such as 2019. Putting calves into muddy pen conditions is far from desirable, but holding calves on the cows deep into fall increases the risk of adverse winter weather and tends to pull body condition off the cows.

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.

A series of arrows on two of the cows labeled Y, Z, X represent feeding motions recorded by the muzzles, while two variables labeled T-0 and T-1 represent "lag" variables expressed by lowering their muzzle to the feed bunk table to eat.

Nutritional Needs Prior to Calving

Nutrition during late gestation plays a large role on the future calf as well as the dam. It is during the last 60-90 days of gestation, or the pre-calving period, that impacts the calf’s survivability, long-term health and overall production.

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.
