They may cause temporary and mild diarrhea in livestock not accustomed to them, but should not affect their health or performance. 1,000-2,999 ppm: These waters should be satisfactory for all classes of livestock.Less than 1,000 ppm: These waters have a relatively low level of salinity and should present no serious burden to livestock.Sulfates: Water levels of 2,000-2,500 ppm and sulfate levels in foodstuffs allowing the animal to attain a level of 4,000 ppm or greater can be associated with a neurological disease in cattle causing blindness. Nitrates: 100 ppm or less should not harm livestock.100-300 ppm should not harm livestock by itself, but beware of additive effects when animals are exposed to or grazing foodstuffs containing increased levels of nitrates (sudan, haygrazer and johnsongrass). Suggested uses of livestock water containing different levels of contaminants are listed below: (remember 1ppm = 1mg/liter of water) Oilfield drilling sites and saltwater disposal wells.Īgriculture application of nitrate and sulfate fertilizer.Īnimal manure and human waste control systems. Soil minerals and salt leaching from the ground. Oklahoma has many potential sources for run-off pond water contamination. of body weight and this estimate can double for cows nursing calves.
Water intake for dry beef cows is around 1-1½ gals./100 lbs. Water consumption is dependent on many factors. Unsafe levels of salt and toxins depend on the age of the animal, its stage of production and the amount of water consumed each day. Excessive salinity (salt) in livestock drinking water can upset the animals’ water balance and cause death. Decreased intake can adversely affect health, reproduction and growth. Water is the one most important nutrient required by livestock. When drought causes a great reduction in surface water available in farm ponds, the issue of water quality becomes nearly as important as quantity of water available. Summer has arrived but there are many areas that don’t get enough runoff water to adequately fill the stock ponds, forcing producers to move cattle looking for forage and water.
