We present measurements of stable carbon, nitrogen and oxygen isotope ratio values in cow milk, forage and drinking water collected in Belarus. Milk, water and forage were sampled in Brest, Gomel, Grodno, Minsk and Mogilev regions during summer and winter seasons. δ13C and δ15N values in dried milk samples ranged from –30.2 to – 20.0‰ and from +3.63 to +5.66‰, respectively. The lowest δ13C values were obtained in the Mogilev region in summer. δ18O values in drinking water were quite constant
