Livestock Water Testing Services Offered by South Dakota State University Extension

South Dakota State University (SDSU) Extension is providing on-site livestock water testing services across the state. These services are available at SDSU Extension regional centers and select county offices. Monitoring the quality of livestock water is crucial as poor water quality can negatively impact animal growth, reproduction, and overall productivity. In some cases, contaminated water or water deprivation can lead to severe health issues and even death in a short span of time.

Despite the significant snowfall during winter, recent water tests have revealed marginal water quality. The presence of fence-high snow does not guarantee that dugouts and dams were flushed out with fresh water. While rainfall is beneficial, it doesn't necessarily dilute water sources to safe levels. Therefore, it is essential to collect water samples and have them tested.

To have water tested, clean plastic or glass containers such as sanitized water or pop bottles can be used. A free quick test using an electro-conductivity (EC) meter is conducted to determine total salts in the water. Depending on the results and consultation with an SDSU Extension specialist, additional laboratory testing may be recommended at the producer's expense.

Water appearance can be deceptive, and even seemingly clear water may be of poor quality. Furthermore, some water sources may contain high levels of total salts regardless of the weather conditions. Continuous monitoring of both water quality and quantity is vital to maintain a productive livestock program.
