It is not ideal for animals to have to drink directly from puddles, ponds, streams and other surface water. Bacteria and other pathogens can contaminate surface runoff, which also can be a source of parasite infestation.
animals if each paddock has an appropriately placed water tank. These can be either permanent tanks or portable tanks. Some research supports the idea that clean water has a positive effect on animal performance. Researchers in Alberta found that steers provided with fresh water gain 2.6 pounds per day, compared to 2.0 pounds per day when provided with pond water. Texas A&M University and University of Nebraska studies also indicate that water quality has an impact on animal performance. Surface waters such as ponds and streams can serve as satisfactory sources, but only if the animals’ access is limited. The Noble Foundation in Oklahoma found that uncontrolled access to ponds or streams leads to loitering and socializing at the waterhole. This contributes to the transfer of internal parasites. Even controlled-access facilities

that are larger than necessary encourage animals to loaf. The result is erosion, water pollution and destruction of cover. Here are some other things to consider: • Water contaminated with manure may develop toxic, blue-green algae which can poison livestock and cause muscle tremors, liver damage and death. • High nitrates interfere with the animal’s ability to absorb oxygen. • High salinity causes a form of dehydration. • Bacteria cause diseases, such as leptospirosis and brucellosis. • Sheep and goats tend to be more particular about water quality than cattle. Calves will also avoid fouled water to a greater degree than cows. • Producer experience has shown significant increases in weaning weights and average daily gain for stockers when provided good, clean water.
