Assessing the nitrate content in livestock drinking water of Namakkal
district in Tamil Nadu

A study has been carried out to estimate the level of nitrate content level in different sources of water subjected to livestock feeding. Approximately, 1160 water samples were collected from Namakkal districts comprising 15 blocks and in each block two village were selected. The nitrate was analyzed by using kit method. The Nitrate level showed that 84.3% of samples had 10-50 ppm, 25.5% had 51-100 ppm, 4.1% had 101-300 ppm, and 0.2% had above 300 ppm and 20.1% had traces of nitrate content respectively. From the result analysis, it has been suggested that water samples below100 ppm of nitrate after storing 1 or 2 days should be suitable for the consumption for dairy cattle.
