Water: The #1 Nutrient

Ask any veterinarian of feed specialist what the #1 nutrient is, and you may get a variety of answers.  However, on a pound per pound basis, livestock and poultry will consume over twice as much water as they will any other substance.  Water is critical for any animal to maintain good health, but unfortunately for the producer, it is often overlooked when production problems arise.

Water systems can become contaminated either from groundwater sources or from the environment in the barn.  It is possible for coliform bacteria to enter a well due to poor construction, shallowness of the well, or abandoned wells in the area.  However, the barn environment is by far the biggest threat to bacterial contamination.  Coliform bacteria are easily conveyed through the drinking water system by the animals’ daily activities.  In swine, salmonella and dysentery are common results of water-born bacteria. In poultry, bordetellosis, coryza, and blue comb are a few examples of diseases that are spread through the water system.

Signs & Symptoms

On the Farm

  • Recurring diseases such as salmonella and dysentery sours and looseness in livestock and poultry.
  • Low conception rates.
  • E-coli bacteria infection.
  • Poor feed conversion.
  • High medication cost.
  • Water troughs coated with slimed from hydrogen sulfur or iron bacteria.
  • Plugged screens on waters.
  • Livestock tanks full of algae slime.

Contaminated Water is Best Treated in the Well

The MARK 3 Dry Pellet Chlorinator is most often mounted directly on the well and drops a chlorine pellet down the shaft into the well water.   It is wired into the pump’s electrical circuit and runs only when the pump is running, metering chlorine in proportion to water usage.  A timer mechanism allows for variation in pump size and water quality.  As the pellets sink to the bottom of the well and dissolve, they perform 2 important functions: sanitation & oxidation.  This is what enables chlorine to treat some common well water contaminants:

  1. Coliform Bacteria. Chlorine kills this bacteria if given sufficient contact time.  In most cases, the water in the well will meet the criteria.
  2. Iron Bacteria. This nuisance bacteria is most noticeable by the slimy red coating it leaves in the water system.  Severe cases can plug pumps, pipes and filters.
  3. Hydrogen Sulfide. This is most described by its distinct smell.  Rotten egg, sulfur, and sewer gas are common descriptions.  A black, slimy accumulation may occur causing the same problems as iron bacteria.
  4. Algae. Shallow wells and water drawn from ponds may be contaminated with surface run-off and biological debris from both plants and animals.  These water sources should be chlorinated (or some other sanitation) on a constant basis.
  5. Iron and Manganese. These are two common minerals found in many water supplies.  They may show up as rust or black deposits on plumbing.  In larger amounts, water may appear rust-colored and have a metallic taste.  Chlorinating this water will oxidize the iron or manganese, reducing the amount that sticks to plumbing, and change it to a form that allows filters to catch it.
