Milk production and milk composition are of prime economic importance for farmers. Thus, as protein volume in feed is increased, not only more milk is produced, bet also threats for environmental pollution are growing. The objective of this work was to establish milk urea content in different farms. Individual cow milk samples (n = 14873) were collected monthly from September 2009 to September 2011. It was established in this study that forecasted ammonium pollution emitted daily from agricultural holdings using tie stall housing may comprise 91.4 – 104.0 g from cow, while amount emitted by freestall housing holdings may constitute 93.9 – 95.9 g from cow daily.
