Beef producers often worry about having too much water or not enough on their farms. However water quality, particularly in fluctuating stock water sources, may go unnoticed. As the summer wears on, evaporation, low rainfall, and consumption can cause the quantity and quality of surface water to dwindle. Meanwhile, hot and dry conditions cause cattle to be at their peak water demand.
“Poor quality drinking water is often a factor that limits intake,” said Leah Clark, livestock specialist with the Saskatchewan Ministry of Agriculture. “When we limit intake we limit production,” she explained in a recent webinar, adding that poor stock water quality can impact animal performance through reduced gains and decreased reproductive success. In severe cases, water quality issues can lead to disease and death. Testing stock water may be particularly important during a drought, when minerals and nutrients can become concentrated as water tables drop in surface or ground water.
Recent producer surveys indicate most Canadian farmers need to test water more often. In western Canada, 59% of producers reported they don’t test their water, and only 17-41% of Quebec and Ontario producers reported testing water once every five years.
