SDSU Extension offering livestock water testing across state

BROOKINGS, S.D. – South Dakota State University Extension is encouraging producers to take advantage of its free, on-site livestock water testing services across the state.
“It’s never too early to start testing your water,” said Robin Salverson, SDSU Extension Cow/Calf Field Specialist. “Your animals’ health should not be the indicator of water quality. Be proactive and test the water prior to turnout to protect yourself from loss in productivity or death.”
Poor water quality can hurt livestock’s growth and reproduction, making it critical to monitor their water supply. Severely contaminated water can cause illness or death. Salverson said testing is the only way to be sure because even clear water can be of poor quality.
SDSU Extension offers water testing services at all eight regional centers and at county offices across the state. Samples must be collected in a clean plastic or glass container such as water bottles, pop bottles or jelly jars.
A quick test is conducted free of charge with an electro-conductivity (EC) meter to determine total salts in the water. After the results are reviewed by an SDSU Extension field or state specialist, Salverson said additional laboratory testing may be suggested. Additional testing offered by private laboratories will be at the cost of the producer.
Salverson said there are many factors that determine water quality, including snowfall, rainfall and grazing management strategies. South Dakota soils tend to be high in salt content, which can raise the salt levels in dugouts, creeks and streams.
“Really consider your grazing management and how that is influencing or impacting your water,” Salverson said.
