8.1 mineral content
Although broilers are tolerant of some minerals in excess,(calcium and sodium, for example), they are very sensitive to the presence of others. Iron and manganese tend to give water a bitter taste that may decrease consumption. In addition, these minerals support the growth of bacteria. If iron is a concern, filtration systems and chlorination are affective controls. It is advisable to filter the water supply using a filter with a mesh of 40-50 microns. The filter needs to be checked and clean at least weekly.
