When assessing animal performance problems, the feed is typically analysed, whereas water analysis is often overlooked. In some instances, re-formulation of diets may be required to reduce the negative effects of poor quality water. Water Sample Analysis Analysis of water samples can be done in different ways. Bacterial analysis can determine if the water contains micro-organisms such as harmful bacteria. Chemical analysis is used to determine the mineral concentrations in water.
Many factors can affect water quality.
The information in Table 1 illustrates some of the current accepted criteria used to determine water suitability for livestock production by the 1987 Canadian Task Force on Water Quality. A typical water analysis should consist of several basic tests to evaluate a sample. TDS measure the sum of all inorganic material dissolved in a sample of water. All minerals elevate TDS, however only a few cause health problems. For example, high levels of calcium and magnesium have little effect on health while contributing to the TDS and hardness of the water.
