Incidence of Nitrate Toxicity in Buffalos in Andhra Pradesh

Abstract

Nitrate poisoning occurs in animals due to consumption of fodder or drinking water containing high nitrate levels. Incidence of nitrate poisoning occurred in 20 buffalos of Santhanuthalapadu village of Prakasam dist.  Affected animals exhibited symptoms like respiratory distress, cyanotic to brownish discolouration of mucous membranes and death in some cases. Ailing animals recovered following treatment  with 1% solution methylene blue. The qualitative test for nitrate in water samples and fodder samples was done with  Sulphanilic acid and diphenylamine reagent. Quantification was done by AOAC methods. The farmers were advised to give nitrate free water to the animals and to get the water samples often tested for nitrates.
