Water constitutes 75% of the Earth. Our bodies are made up of more than 60% of it. We can only survive 4 days without water. It is considered one of our most important natural resources and is the most essential nutrient to our diets. This is also true for livestock.
Most livestock can survive for two months without food but cannot go more than a week without water. Water is very important to all animals. It is required for bodily functions like digestion and lactation.
Livestock must have access to high-quality water.
Test your water for salt and toxins
Knowing what’s in your water is important because certain factors can affect livestock performance, cause health problems, and even lead to death.
The most common factor making water unsatisfactory for livestock is high salinity. High salinity is an excessive concentration of dissolved salts. Other factors that can affect water quality are nitrates, sulfates, alkalinity and toxic elements.
The best way to find out the quality of your water is to have it tested. A quality analysis can test for total coliform bacteria, pH, total dissolved solids, salinity, hardness, nitrates, sulfates and toxins.
Make sure water is clean and fresh
Livestock should have access to clean, fresh water at all times. Besides testing, there are a few ways you can make sure your animals have high-quality water.
- If your livestock get water from tanks, clean those tanks regularly.
- Animals that have individual water buckets (such as calves in hutches) need to have their pails cleaned and disinfected regularly.
- If your animals have access to ponds or streams, try to limit those access points to keep the water cleaner.
Water is an essential but often overlooked nutrient for all livestock. Giving our animals plenty of fresh, high-quality water will ensure peak health and optimal performance.
The best way to know what’s in your water is to have it regularly tested once a year.
