Have you ever seen a greenish film floating on the surface of the water? Chances are, that was algae. This plant-like microorganism can grow quickly in warm, sunny conditions, and while it may seem harmless, it’s anything but, especially when it comes to livestock troughs. It can significantly reduce the water quality and put your animals’ health at risk. 

At Bar Bar A, we know how destructive algae growth can be, which is why we designed our automatic livestock waters to prevent it. If you’re battling algae in your water troughs, keep reading to learn more about its negative effects, some practical prevention strategies, and when it’s time to consider upgrading to an automatic waterer.

What Is Algae, and Why Does It Grow in Troughs?

Algae are microorganisms that thrive in water and grow in colonies. Like plants, they perform photosynthesis, which means they get their energy from water, air, and sunlight. They often appear as a green film, but can also be brown or black. 

Algae growth typically occurs in stagnant or slow-moving water with plenty of sunlight exposure and warm temperatures. While it can be found in natural water sources like lakes and ponds, open troughs and poorly maintained livestock watering systems are also at risk.

Health Risks for Livestock

Algae growth in water troughs can have a significant impact on the health of your livestock. Animals naturally avoid slimy, discolored, or foul-smelling water — all of which are symptoms of an algae problem. Reduced water intake can lead to dehydration, which can impact feed intake, weight gain, milk production, and overall health. 

Blue-green algae (sometimes referred to as cyanobacteria) is especially dangerous. It can produce toxins that affect the liver, digestive tract, and nervous system, especially in warm, nutrient-rich water. If consumed, these toxins can lead to lethargy, diarrhea, tremors, difficulty breathing, sudden illness, or even death. 

Even without the toxins, algae is still harmful. It can harbor harmful bacteria and parasites that can cause digestive issues, weaken immune responses, and increase the risk of scours. 

Warning Signs That Algae Growth May Be a Problem

Be on the lookout for these warning signs that algae may be growing in your water troughs:

• Green, brown, or black film on surfaces
• Slimy residue or floating clumps in the water
• Musty or earthy odors
• Reduced animal water intake
• Unexplained health issues or performance changes in your livestock

Take immediate action if you see visible algae blooms or a thick buildup, your animals refuse water or show signs of illness after water exposure, or there are sudden changes in the water’s color or odor during hot weather. If any of these things occur, it’s important to isolate your animals from any suspicious water and provide clean, fresh water sources. 

It’s important to note that clear water can still contain algae or toxins. Algae growth often begins on shaded interior surfaces before becoming visible. Biofilm — a slimy layer of microorganisms like algae — can occur on any wet surface of the trough, often hiding in seams or in crevices. Often, water may smell or taste off before any visual signs appear, making it hard to catch algae growth before it’s too late. 

How Automatic Livestock Waterers Help Reduce Algae Risk

Upgrading to automatic waterers from Bar Bar A is one of the most effective ways you can protect your livestock from the dangers of algae. Because the water doesn’t stay in the basin, it doesn’t have the chance to warm up in the sunlight or become stagnant, which means algae doesn’t have the chance to grow. It’s an easy, convenient way to ensure your livestock have access to all the fresh, clean water they need. 

Plus, it’s better for you and your team. Automatic waterers require very little maintenance — no constant refilling and cleaning. This can save you significant time and money in the long run in addition to promoting healthier, happier, animals.
