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.
The goals of applying any crop protection products include: increasing effectiveness, mitigating drift, and maximizing profits. We will focus on mitigating drift, even though all three interact with each other.
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.
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.
As we progress later into the summer, we commonly see an increase in horse fly activity.
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.
Hay that contains sweet clover can be an excellent feed as long as the dicoumarol level is known and feeding management is used to prevent poisoning.
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.
According to the latest climate outlook update, odds are favoring that August 2019 will be cooler than average. The update was released by NOAA’s Climate Prediction Center on July 31, 2019.
