Maintaining clean watering systems on cattle farms aids in overall herd health
For cattle producers, keeping water troughs clean may seem like a small task — but it can make a big difference in herd health and productivity. While waterborne diseases are not a major concern in most cases, clean and appealing water plays a crucial role in keeping cattle hydrated, comfortable and performing their best.
According to livestock experts, the main reason to prioritize clean troughs is not necessarily to prevent disease, but to encourage cattle to drink enough water each day.
“Animals are like people — they prefer to drink from a clean source if given the option,” said Dr. Lauren Rogers, clinical assistant professor and veterinarian.
She emphasized that cattle will often avoid dirty or algae-covered water. Reduced water intake can quickly lead to dehydration, which affects feed consumption, milk production and overall health.
While the risk of disease spreading through shared water is low, unsanitary troughs can still create indirect problems. Organic buildups such as manure, hay, or algae can alter the smell and taste of the water, making it less appealing to animals. In winter, ensuring cattle drink enough can be even more important, since dry air and cold weather often decrease their natural thirst response.
Cleaning doesn’t have to be complicated. Experts recommend using a simple combination of soap, water, and a stiff brush to scrub the trough.
“Just a little bit of Dawn dish soap and a good rinse will usually do the trick,” said Rogers.
For producers who want to disinfect further, a super-diluted bleach or chlorhexidine solution can be used so long as the trough is rinsed thoroughly afterward to prevent any lingering taste or residue that could discourage drinking.
Some ranchers have found creative ways to control algae naturally. A few even use goldfish in their tanks to eat the algae that grows on the bottom. However, this method comes with challenges, as the fish require oxygenated water and can die off if conditions aren’t right.
“Some people like that because it helps keep the water cleaner,” Rogers said. “They have a limited lifespan and there’s different conditions that can cause the fish to die.”
Whether using simple scrubbing, light disinfectants, or even goldfish, the goal remains the same: keep water sources fresh and appealing.
“If the cattle want to drink from it,” Rogers said, “you’re already ahead.”
