Effect of Natural Zeolite, a Slurry Additive, on Physicochemical Slurry Properties and Aerial Ammonia Concentration in the Pig Farm Nursery

The present study was conducted in a control and experimental unit of the nursery on a pig-breeding farm. The commercial preparation, a natural zeolite containing 55% clinoptilolite, was spread directly on the partially slatted floor in a dose of 1 kg/50 m2, as recommended by the supplier. The aim was to asses its effect on the aerial ammonia concentrations and physicochemical slurry properties. The results showed an aerial ammonia reduction of 15 %. Direct sprinkling of the additive on the slatted floor influenced physicochemical parameters which are indicators for the organic loading, as well as the concentration of nitrogen compounds specially ammonium ion reduction for 16 %.
