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.
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.
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.
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.
In some areas of South Dakota, recent precipitation has led to an increase in mosquito activity. To reduce the chances of contracting West Nile Virus, it is important to understand the behavior of the mosquitos capable of vectoring it.
The South Dakota Department of Health's latest update indicated that West-Nile-virus-positive mosquitoes were detected in Beadle, Brookings, Brown, Codington, Hand, Hughes, Lincoln and Minnehaha counties in South Dakota.
As of Aug. 2, 2021, the South Dakota Department of Health indicated that West-Nile-virus-positive mosquitoes were detected in Brookings, Codington, Hughes, Lincoln and Brown counties in South Dakota.
Nitrate poisoning is something we think about with forages such as millet, oats, corn, sorghum, sudan, kochia and others that have been fertilized or if there is a drought, but water can also be a contributing factor.
To have a healthy diet all year long, consider all options (fresh, frozen, and canned) when it comes to eating fruits and vegetables.
With warmer temperatures, the conditions are right for blue-green algae blooms. Different species of blue-green algae contain various toxins, which can poison livestock, resulting in rapid death.
